Describe the scope of work in detail. Please include a summary of key deliverables.

We hired WizzDev to modernize and migrate our backend infrastructure from AWS OpsWorks to AWS Systems Manager. The engagement started with an in-depth audit of our AWS environment to identify outdated components and architectural improvements. As part of the preparatory phase, WizzDev upgraded the underlying OS (Ubuntu) and key software packages, including PHP and Apache, ensuring compatibility with newer AWS services.

The actual migration was carried out under tight time constraints, as our infrastructure supports mission-critical backend services for both mobile and web apps used daily by PressPad’s global customer base. Despite this, the transition was completed seamlessly with no downtime or service degradation.

WizzDev managed the entire project from planning to execution, including environment reconfiguration, Systems Manager setup, and deployment automation. They provided detailed documentation covering the new infrastructure setup, deployment instructions, and maintenance procedures.

Key deliverables:

AWS infrastructure audit report
OS and software package upgrades
Migration from AWS OpsWorks to AWS Systems Manager
Configuration of deployment and operational workflows
Comprehensive technical documentation

RESULTS & FEEDBACK

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

The migration was completed on time and with zero downtime, which was critical since our backend supports live traffic from mobile and web apps used by PressPad clients. Additionally, the upgrade reduced our reliance on deprecated AWS services and positioned us for easier scaling and future maintenance.

Most importantly, the new setup enabled us to publish new mobile apps, onboard new customers, and deliver customized implementations of our solutions to meet specific client needs.

Other outcomes:

0% unplanned downtime during migration
Improved infrastructure maintainability and observability
Fully compliant and up-to-date stack

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

Project management was very good — all deliverables were completed on time, and WizzDev was very responsive throughout. Communication between their engineers and our developers was smooth and effective, making collaboration feel seamless. When we needed to accelerate certain stages, they reacted quickly and adjusted without asking too many questions and without compromising quality.

What was your primary form of communication with WizzDev?

Virtual Meeting
Email or Messaging App

What did you find most impressive or unique about this company?

What impressed us the most was that we were looking for an external company capable of executing this project across Poland, Japan, and the UK. Only WizzDev was willing to take on the challenge and successfully deliver the project within the time frame and budget we had to offer.

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

Honestly, there’s really nothing to complain about. The entire process was handled professionally, and we’re very satisfied with the outcome. The rules and expectations were very transparent from the very beginning, which made the whole collaboration smooth and hassle-free.

Initial planning could've been better, but it stems from the a lot of unknowns that we had along the way, due to the unique circumstances of the project requirements. We were after a very small product footprint, ans it had its own challenges that manifested along the way - but all of them where fixed.

I was impressed with their bdy of work, and they could point me to projects that were very relevant.

Their questions showed not only great insight but a real underetanding of the domain. They were also not put off by starting small to align with my budegetary constraints. As a founder of a small company I have limited understanting of many areas of hardware, firmware and software development and they have been extremely patient and supportive in getting a test platform up and running and enabling to sucessfully test the application.

The developer I was working directly with was extremely creative and went above and beyond to reach a satisfactory conclusion. I could also see the benefit of the active support of a range of knowledable colleagues and even the senior management team.

WizzDev integrated a laundry company's firmware with another microcontroller. They added web services to control the power plug directly and ensured that an OTA update mechanism would be possible in the future.

Equipped with incredible development resources, WizzDev stabilized the firm's system and dramatically reduced the rate of support issues. Transparent and responsive, they quickly delivered the required outputs. What stood out the most was how they skillfully addressed the client's technical issues.

BACKGROUND

Please describe your company and your position there.

I am the founder of laundrify. We build a Smart Home product to monitor Washing Machines and Dryers via App.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire WizzDev?

We asked WizzDev to re-implement an existing Firmware for the Power Plugs that was created during a PoC phase.

SOLUTION

How did you select this vendor and what were the deciding factors?

WizzDev applied for our job posting on upwork. After interviewing with a few other applicants as well, it was the thoughtful preparation of an initial project plan with the flexibility to revise it after each iteration, which led me to choose WizzDev as a partner to implement the Firmware.

Describe the project in detail and walk through the stages of the project.

The firmware is running on an ESP8266 that needs to communicate with another microcontroller on the same PCB using a proprietary protocol, which was the first milestone in the project. The communication with our REST API was added afterwards and finally some web services to control the Power Plug directly were provided. In order to support future enhancements an over-the-air (OTA) update mechanism was added as well.

How many resources from the vendor's team worked with you, and what were their positions?

The main work was done by 2 firmware developers, coordinated by a project manager who also had a strong technical background.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

The new Firmware significantly reduced the rate of support issues and the overall stability of the system. The initial release required a bug fix version delivered very fast and does a great job now.

How effective was the workflow between your team and theirs?

We received a weekly status update along with a plan of the tasks for the upcoming week. Each task has been estimated before starting it and discussed transparently if exceeded.

What did you find most impressive or unique about this company?

The firmware developers were directly involved in calls which made it very comfortable to discuss technical issues.

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

At first, we haven't had access to their project management platform and code repository, making it more difficult to keep track of all tasks. However, this has been addressed and changed in a follow-up project, which was great to see.
