MUMPS/ObjectScript/.NET Developer | Backend | 4+ YoE

Hi everyone!

My name is Nikita Mikhailov, and I am a backend engineer with 4 years of experience specializing in InterSystems IRIS, ObjectScript, MUMPS, and .NET. I thrive on untangling legacy codebases, solving complex concurrency or performance bottlenecks, and building clean, modern APIs.

Key Highlights from my work:

• Performance Optimization: Slashed average API response times by 90% (from >1s down to ~100ms) by implementing custom caching layers and background processing.

• Legacy Modernization & APIs: Redesigned B2B integration layers from scratch, introducing structured programming paradigms to legacy MUMPS code and building custom REST APIs (including FHIR protocols).

• System Integrations & .NET: Engineered robust integrations with banking gateways and government services that boosted transaction success rates by 25%, alongside hands-on experience building .NET/WPF desktop tools.

What I’m Looking For: I am seeking my next full-time or contract role as a Backend Engineer or InterSystems Developer. I am highly flexible and looking for high-impact projects where I can leverage my hybrid IRIS and .NET skillset to scale platforms or build new integrations.

I am based in Serbia, and am open to Remote work or roles offering relocation.
