Vadym K.

I’m a Full Stack Developer with 𝟴+ 𝘆𝗲𝗮𝗿𝘀 of experience and 𝟯𝟱+ 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝘀 in production, from fintech to defense. Backed by a senior team, I can cover any role or technology your project needs. 📣 Let’s discuss your project right now, and I’ll help you clarify requirements!

With 8+ years of experience and 35+ products in production across fintech, healthtech, energy, industrial, maritime, defense, real estate, asset management, e-commerce, and SaaS. I build web applications, backend systems, RESTful APIs, desktop applications, and internal platforms on ASP.NET Core and Microsoft Azure that handle real production load. I own delivery end-to-end, from database design to deployment, release, and new features after launch.
