Software Engineer · Full Stack (.NET / C# · TypeScript / React)
Production ASP.NET Core and React on multi-tenant enterprise SaaS · 1400+ competitive-programming problems solved
Software engineer with 2+ years of professional experience, currently Associate Software Engineer at Cefalo, building multi-tenant enterprise SaaS on .NET 8 / ASP.NET Core / EF Core / Azure with TypeScript + React front ends. I ship features end to end — REST API, frontend, and database schema — and I currently work on an enterprise scheduling-data exchange platform for a Norwegian client.
- Own the full delivery cycle: database schema → API → UI → deployment
- Favour SOLID, layered separation, typed codebases, structured logging and RBAC
- Designed and built a production event-driven notification subsystem with background job processing
- Introduced AI-assisted development into a production team workflow — code review, testing, documentation
- .NET backend — ASP.NET Core and EF Core services with ASP.NET Identity, RBAC, global error handling and xUnit coverage.
- Full-stack delivery — from the database schema up to a React + TypeScript UI, owning the whole path to production.
- Event-driven design — background job processing and real-time notification with Hangfire and SignalR.
- AI-assisted engineering — agent-based workflows (custom skills, hooks, MCP servers) applied to real team practice, not demos.
- Problem solving — 1400+ problems solved on Codeforces and LeetCode; ICPC, NCPC, and national hackathons. I bring contest-grade edge-case instincts to production work.

This is my GitHub profile repository — alongside this README it doubles as a notebook of things I've written, learned, and competed in.
- Blog — write-ups and notes: customizing Windows PowerShell, issues faced with React + Vite + TS and ASP.NET, refactoring, and code smells.
- Competitions — a log of programming contests and exhibitions I've taken part in (ICPC, ITverse, AUST CSE Carnival, and more).
- Diary — a running learning diary of algorithms and competitive-programming topics, with code and intuition.
- Learnings — structured checklists tracking topics I'm working through (e.g. Android development).
