BACKGROUND
Please describe your company and position.
I am the Head of Product of a funding platform.
Describe what your company does in a single sentence.
We are a match-funding platform for art, photography, science, and technology.
OPPORTUNITY / CHALLENGE
What specific goals or objectives did you hire Techstack company to accomplish?
We’d tried face-matching before and, honestly, it had always fallen short. The technology just wasn’t accurate enough to handle the real-world variety we deal with: different lighting, angles, clothing changes, and unpredictable event conditions. For our platform, that accuracy wasn’t just a nice-to-have, it was the whole point. We wanted a way for event participants to quickly find their photos and for photographers to sell them easily, without the endless manual sorting and guesswork. That’s when we turned to Techstack.

Describe the scope of work in detail. Please include a summary of key deliverables.
Techstack company handled everything end to end. They provided AI and deep learning expertise, full web development, cloud architecture, and quality assurance. Their scope included building a deep convolutional neural network model for face detection and matching, creating a web portal where users could search photos by selfie, bib number, or event timeline, and integrating watermarking and payment features. They also restructured our backend into a serverless cloud setup to cut hosting costs in half while keeping the performance rock solid.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
The results were exactly what we hoped for. The AI-powered matching worked across a huge variety of image conditions, allowing event participants to find their photos within seconds. Photographers could upload, tag, watermark, and sell images directly through the platform, which simplified their workflow and opened new revenue opportunities. Event organizers no longer had to manually store, sort, or distribute photos, which saved a massive amount of time and effort. On the business side, the backend refactor immediately reduced ongoing costs, which will have a long-term impact as the platform grows.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
The whole process felt seamless. Every milestone was met on time, and they kept communication open so we always knew exactly where things stood. It felt less like handing off a project to an outside vendor and more like working with an experienced in-house team that took real ownership, caring not just about getting everything technically right, but about making sure it truly met the product’s needs and delivered value to the users.

We needed a partner who could help us take our QA process from chaotic and manual to streamlined and automated.

Describe the scope of work in detail. Please include a summary of key deliverables.
From the very beginning, Techstack impressed us with how quickly they understood our system and where the problems were. They started with a detailed QA audit that highlighted the gaps in our coverage and the processes that were slowing us down. After that, they built a custom automation framework tailored to our product architecture. It covered key user flows through automated smoke tests and integrated seamlessly into our CI/CD pipeline. On top of that, they set up an analytics and reporting layer that gave us clear visibility into test results and quality trends. Their documentation and onboarding materials made the final handover smooth and easy for our team to adopt.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
Manual testing was reduced to a minimum, and we saw a significant drop in regression issues. Because automation was fully embedded into the pipeline, our development and QA teams started working in sync, which led to much more stable and confident releases. Testing cycles that once took several days are now finished within hours.

What specific goals or objectives did you hire Techstack company to accomplish?
We brought Techstack on board when our language learning app started struggling with real-time audio. The conversations didn’t sound natural enough, there was lag between AI responses, small glitches in playback, and moments of silence that made users lose the flow of dialogue. We needed a team that could not only solve deep technical issues but also understand the product experience we were aiming for and an interaction that felt smooth and human.

Describe the scope of work in detail. Please include a summary of key deliverables.
Techstack took full responsibility for the mobile implementation. They built a reliable bridge between our backend’s dynamic audio generation and the React Native client, and developed a native iOS module in Swift that could process and stream tiny audio chunks in real time. Their solution completely eliminated the “clicks” and gaps between audio segments. They also added adaptive playback controls and optimized the buffering system so that the experience stayed stable even on low-end devices or slower networks.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
Audio playback that used to lag by several seconds became nearly instant, and the glitches were almost completely gone. Our engagement metrics started climbing, users were spending more time in conversation mode and feedback highlighted how natural the dialogue now felt. The AI voices finally flowed without interruptions, and the entire experience became much more immersive.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
Working with Techstack was easy from start to finish. They were fast, highly organized and transparent about every step of the process. Despite the technical complexity, communication was effortless and every milestone landed right on schedule.

The Techstack team built the Android app from scratch, focusing on stability, responsiveness, and usability. They created a reliable Bluetooth pairing and management system for helmet communicators, implemented adaptive noise-cancellation for changing riding environments, and built a crash detection system that automatically sent alerts to emergency contacts. The app also included real-time GPS-based location sharing for group rides and over-the-air firmware updates for helmet communicators. The interface was designed to minimize distraction: everything about it felt lightweight and rider-friendly.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
Within six months of launch, it surpassed 500,000 downloads with a 78% retention rate and a strong adoption rate for premium features.

Beyond the numbers, it helped shape a community of riders who now rely on the app for safety and connection.
Describe their project management. Did they deliver items on time? How did they respond to your needs?

Techstack team began by reviewing our existing system to understand dependencies and bottlenecks, then proposed a step-by-step modernization approach that minimized risk. The new architecture supports multiple tenants and contexts while maintaining excellent performance and stability. Alongside the technical rebuild, they introduced smarter data flow management and improved our financial planning tools. They worked closely with our internal developers to ensure compatibility with older .NET framework components while implementing the transition to .NET 6.

We started seeing measurable improvements within the first few months. Performance increased noticeably, especially when running complex financial reports or simulations. Maintenance time decreased, since modular components can now be updated without affecting other parts of the system.

Describe the scope of work in detail. Please include a summary of key deliverables.
The Techstack’s team quickly discovered that our existing monolithic structure wasn’t going to hold up long-term. Instead of patching it, they mapped out what a scalable, modern architecture could look like, including DevOps processes, database structure, and security layers. They also estimated realistic development timelines and costs, which helped us avoid underbudgeting. Their roadmap clearly separated what we needed for an MVP and what could come later, which was a huge help in preparing our funding materials.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
By the end of the audit, we had a much clearer picture of our product. We finally understood which features were underdefined, where the technical debt was hiding, and what a rebuild would actually cost and deliver. That level of clarity changed how we approached the next stage of the company. The documentation they provided became the base for our investment proposal, and it still guides our team today.

The whole process was run with precision but never felt rigid. Techstack’s team communicated constantly, explained everything in plain terms, and treated the audit as if they were part of our internal tech department. It was obvious they cared about the outcome, not just the deliverables.

Techstack company built an automated reminder service that sends notifications to patients based on their treatment timelines and developed a script to automatically restart microservices in our staging environment whenever updates are made.

We saw the first impact in a month. The system became faster and far more stable, and the automated reminders helped improve patient engagement in a very real way. Developer time was reduced, errors dropped, and we could finally rely on a workflow that just worked.

Techstack company has developed the mobile side of a language learning app. The team has built a stable and efficient bridge between the backend's dynamic audio generation and the React Native frontend.
Techstack company's work has reduced the average playback delay from a few seconds to almost real time and the glitch rate to nearly zero. The team has impressed the client with their project management style, communication, and ability to handle complex, cross-platform engineering challenges.

BACKGROUND
Please describe your company and position.
I am the CEO of a language learning app.
Describe what your company does in a single sentence.
We are an educational center where we promotes artistic production, discourse, mediation and research and provide education in the contemporary context through its various programs.
OPPORTUNITY / CHALLENGE
What specific goals or objectives did you hire Techstack company to accomplish?
We hired Techstack when our language learning app hit a wall with real-time audio performance. The experience just wasn’t fluid enough, the AI responses felt slightly delayed, and users were getting frustrated with audio hiccups that broke the conversational flow. We needed a technical partner who could go deep into the tech side while understanding that the real goal was to make practice feel as natural as speaking with a real person.

Describe the scope of work in detail. Please include a summary of key deliverables.
Techstack’s team handled the full mobile-side development: from building a stable and efficient bridge between our backend’s dynamic audio generation and the React Native front end; to created a custom iOS module in Swift that processed and streamed small audio chunks without delay or “clicking” between transitions. They also introduced adaptive playback controls, fine-tuned the buffering logic, and made sure the streaming quality remained smooth even on weaker devices or slower connections.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
The average playback delay dropped from a few seconds to almost real time, and the glitch rate went down to nearly zero. We started seeing noticeably higher session durations and better retention within the conversation module. The biggest win, though, was how natural the AI voices began to sound - users could finally have smooth, flowing dialogue without that awkward pause or audio pop that used to break immersion.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
Their project management style was one of the things we appreciated most. They worked quickly but never cut corners. Every milestone was delivered on time, communication was open and easy, and the team took complete ownership of the work.

What did you find most impressive or unique about this company?
We were impressed by how confidently Techstack’s team handled complex, cross-platform engineering challenges. They built a real solution from the ground up, balancing technical depth with a clear understanding of how people actually use our app. They combine deep engineering expertise with a product mindset. It’s the kind of collaboration that raises the bar for what you expect from a development partner.
Are there any areas for improvement or something Techstack company could have done differently?
There wasn’t a single area I’d point out for improvement.
