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.

OPPORTUNITY / CHALLENGE

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?

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. The product also attracted the attention of several major helmet manufacturers, resulting in new partnerships and hardware integrations. 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.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

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. The new structure also helped reduce operational costs that used to require full rebuilds and now only needs targeted updates.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

The Techstack team approached the work with real ownership, checking in frequently, raising potential issues early, and ensuring everything aligned with our long-term goals. Even when we adjusted requirements midstream, they managed those changes without disrupting delivery. It was a very smooth experience.

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.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

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.

They gave us clarity, structure, and a plan we could follow to launch our product.

Are there any areas for improvement or something Techstack company could have done differently?

No. The process was efficient and insightful.

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.

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?
