You will get a fast-delivered feature for your product


Project details
You will get a well-designed API/app/microservice cause I love my job and care about the result. I have more than 6 years of enterprise development of web API and apps, but microservices are my new passion. I prefer transparency in work and could discuss current progress or issues or some adjustments if needed at any time. I respect deadlines and pay attention to risks and blockers that highlight immediately and prepare a plan how to deal with them. If you're interested in all that I've described please contact me.

Senior .NET Architect | Distributed Systems & AI Integration
Belgrade, Serbia - 8:39 am local time
That's where I come in.
I'm a senior .NET engineer and software architecture consultant with enterprise experience, specializing in backend systems design, distributed architecture, and code review for teams that need to move fast without building themselves into a corner.
What I typically help clients with:
Architecture reviews - finding the structural problems before they become production incidents
Distributed systems design - microservices, event-driven architecture, CQRS, API design
Code review and technical due diligence - for teams, CTOs, and investors who need an honest picture
.NET modernization - moving legacy systems toward something maintainable and scalable
Increasingly, I also help engineering teams integrate AI into their existing .NET workflows - not as a gimmick, but as a practical layer that makes products smarter and teams more productive. This includes building AI-powered features via LLM APIs (including Claude and OpenAI), designing RAG pipelines, and connecting AI capabilities into production backends in a way that's actually maintainable.
I don't just write code and disappear. I bring the perspective of someone who has seen what happens when architecture decisions are made under pressure, and I help you make better ones before that pressure arrives.
If you're building something serious on .NET and want a senior technical voice in the room - let's talk.
