OPPORTUNITY / CHALLENGE

What specific goals or objectives did you hire EvaCodes to accomplish?

• We were at a point where the product roadmap had more on it than our internal team could move through at a reasonable pace. A few initiatives had been sitting in planning longer than anyone was comfortable with — new interactive content modules, improvements to the team collaboration interface, and some infrastructure work that kept getting deprioritised. We needed a dev partner who could pick up a defined scope and run with it without needing constant oversight. That was the ask.

2-5 Employees

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

EvaCodes worked across two main areas. First, they developed new interactive content modules for the platform — gamification elements, survey embeds, and countdown timer functionality compatible with major email clients. Second, they redesigned the team management interface: the roles and permissions UI that our enterprise users use daily to coordinate across larger production teams. On top of that, they handled integration testing to make sure everything worked cleanly within our existing system. Key deliverables: three new interactive modules, a redesigned team management UI, and integration QA documentation.

RESULTS & FEEDBACK

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

The interactive modules got adopted faster than we expected. The gamification element in particular became a talking point — it fed into content we published and got picked up by our audience in a way that felt organic, not forced. The team management UI update reduced friction during enterprise onboarding, which our customer success colleagues noticed and mentioned unprompted. From a communications standpoint, having tangible new features to announce on a predictable schedule made a real difference to how we plan campaigns and partner updates.

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

Structured and reliable. They ran sprints with clear scope, gave updates without needing to be chased, and flagged potential blockers early enough that nothing became a crisis. When I needed something for an announcement — a demo environment, a feature summary, specific details for a partner brief — they turned it around quickly. I'm not always close to the technical day-to-day, but I could tell things were running smoothly because the information I needed kept arriving when I needed it.

What was your primary form of communication with EvaCodes?

• Virtual Meeting
• Email or Messaging App

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

They cared about how the work would land, not just whether it was technically complete. A few times they asked questions I wouldn't have expected from a dev team — about how a feature would be explained to users, what the use case looked like from a non-technical perspective, whether the naming made sense. That kind of curiosity makes the output better. It also made collaboration easier, because we were clearly working toward the same thing.

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

nothing major, we worked in synergy

BACKGROUND

Please describe your company and position.

I am the Founder & CEO of O-CMO

Describe what your company does in a single sentence.

O-CMO is a platform matching tech service companies with marketing executives and senior experts.

OPPORTUNITY / CHALLENGE

What specific goals or objectives did you hire EvaCodes to accomplish?

When I started O-CMO, the platform lived mostly in my head and in a few Notion docs. I had the matching model figured out, the CMO network was growing, and clients were coming in — but everything ran manually. 
I needed to turn that into an actual product: CMO profiles, a client-facing portal, an onboarding flow, and the internal tooling to manage engagements without me being the glue holding it all together. Finding a dev team that could build something like that without six discovery workshops and a €50K proposal was the challenge.

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

EvaCodes built the core of the O-CMO platform. On the client side: a matching intake flow, a CMO catalog with filters by vertical and seniority, and a client dashboard to track engagement status. On the specialist side: CMO application and profile management, verification status, and a basic pipeline view. 
They also built the CMS layer so I could update content, add new CMO profiles, and publish case studies without touching a developer. Key deliverables: platform frontend and backend, CMO and client portals, CMS integration, and infrastructure setup.

RESULTS & FEEDBACK

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

Before the platform, onboarding a new client took me personally involved at every step. After launch, a significant chunk of that became self-serve. Time-to-first-match dropped noticeably, and we were able to handle more concurrent engagements without adding headcount. The CMO application flow alone brought in more inbound specialist applications than I expected — the product itself started doing acquisition work I was doing manually before.

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

I'll be honest — I'm a difficult client. I know what I want, I change my mind when I see something, and I have opinions about copy and UX that most devs find annoying. EvaCodes handled it well. They pushed back when my changes would've broken the sprint, explained the tradeoffs clearly, and found ways to accommodate most of what I needed without derailing the timeline. Everything shipped on schedule. That's not something I take for granted.

What was your primary form of communication with EvaCodes?

• Virtual Meeting
• Email or Messaging App

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

They understood that I wasn't just building a website — I was building a business tool I'd use every day. That shifted how they approached decisions. They'd ask "how does this work in practice?" before implementing something, which meant we caught a bunch of UX problems before they became support issues. For a founder who's also the main user of the product, that kind of thinking from the dev side is genuinely valuable.

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

I would've liked more proactive input on the product architecture earlier in the project. There were a couple of structural decisions we made in sprint one that we partially revisited later — not because of mistakes, but because nobody stopped to ask "where is this going in six months?" That's partly on me, but a more experienced team might've pushed for that conversation upfront.

BACKGROUND

Please describe your company and your position there.

I am the founder of a company that provides public key distribution with an increased degree of security.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire EvaCodes, and what were your goals?

Our system faced the challenges of token turnover between blockchain ecosystems. In order to further develop and intensively grow the product along with modernizing the user experience, we needed an atomic swap solution. The main goal was to implement a fully automated product to track transactions and provide a good environment for token migration. The service had to adapt quickly after network outages and any connectivity failures.

SOLUTION

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

I instructed my manager to post an ad for developers on Upwork. We chose EvaCodes, and have not regretted it at all. The deciding factor in making such a decision was their portfolio.

Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.

During the development of technology solutions, the developers encountered some problems. They noted large differences in consensus, complicating blockchain synchronization. The team decided to implement several non-standard solutions ensuring the stability and smooth functioning of the service. This is a request to Bridge instead of hashing.

Thus, a user checks the availability of funds in an account. A special bot sends a swap transaction for the user's approval. It receives the Ethereum request and approves the swap. The funds are then transferred to Bridge and the private key is returned. This solution makes it possible to transfer native tokens without any problems.

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

It took a large team of blockchain developers with the necessary competencies and knowledge of Ethereum ecosystems to do such a complex job. Ten specialists were involved in the project. Among them were two blockchain engineers, two backend developers, three blockchain developers, two QA, and one PM.

RESULTS & FEEDBACK

Can you share any measurable outcomes of the project or general feedback about the deliverables?

As a result, we have got a quality product for decentralised token exchange:

• tokens are available for transfer to the native chain;
• there is no interoperability between the blockchain systems, which allows the transfer of assets directly;
• the developed Bridge between the systems is characterized by a high degree of performance and security.

In addition, the Bridge monitors and verifies the approval of transactions in the network, increasing the reliability of the system.

Describe their project management style, including communication tools and timeliness.

We contacted the developers and the project manager via zoom.

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