About this gig

Looking for a skilled developer to bring your SaaS idea to life?


I am a .NET developer with 8 years of experience building secure, scalable and clean-architected web applications. Whether you are starting from scratch or need to scale and improve an existing system, I deliver production-ready code tailored to your business.


What I offer: ASP.NET Core Web API development, admin and user dashboards, payment integration (Stripe, virtual POS), role-based access with JWT and Keycloak, MS SQL Server and PostgreSQL database design, Redis caching, background jobs, and clean code following SOLID principles.


I have built enterprise platforms that handled 15,000+ transactions a day, so I design for real traffic and failure cases, not just the happy path.


Tell me what you are building and I will reply within an hour with the right scope and a realistic timeline. You can also order Basic directly and I will send a custom offer if the project turns out larger.

I work with PostgreSQL, Redis, RabbitMQ, Docker, Docker Swarm, Elasticsearch, and CI/CD. I follow Clean Architecture, SOLID, and DDD principles to deliver reliable, maintainable solutions.
