Project challenges and outcomes

These case studies cover systems I designed or built, as well as projects whose delivery I led. Each explains the client's needs, the technical challenges, my own contribution and the outcome.

Building and modernizing web products

Two examples of web product work: building a customer portal for a fintech platform and modernizing a large corporate website.

Fintech startup founded by traders and analystsLaunched with real users; operated for more than six months

From trading engine to customer platform

I built the customer portal, exchange account connections, free trials, and payments around the team's trading engine, and added redundancy. Users could choose from four exchanges.

WordPress updated, 100+ changes completed without a rebuild

A nearly decade-old site ran on a virtual machine with an outdated software stack. I completed the requested changes, updated WordPress, PHP and the database engine, added tests, and documented the build and deployment workflow. I deployed the site to test and production environments.

What I can share about private projects

Many projects are internal, covered by nondisclosure agreements or no longer available. Links, screenshots and exact figures are therefore not always available, and some clients cannot be named. We can discuss technical approaches and a similar solution for your needs in writing in English or on a call in Russian, without disclosing protected interfaces or data.

What would you like to solve?

Share a detailed brief, requirements or any materials you already have. If you have none yet, a few sentences about the current situation and your goal are enough. I review every message myself and respond within one business day.

  • You will work directly with me, not a sales representative.
  • A free initial written discussion will help establish whether I can help and where to start.
  • If the project is outside my expertise, I will tell you directly.
