Hi there, I'm Kosta Dinkov πŸ‘‹

Full-Stack Software Engineer (.NET / React) | AI-Augmented, Verification-First Development

πŸš€ About Me

I've been writing code since I was 12 β€” BASIC, then Pascal, then a long list of things since. For the past three years I've owned a production ERP system end to end β€” architecture, backend, frontend, and now AI agents β€” used daily by a 15-person team. That's shaped how I think about AI-assisted development: speed from AI tooling is easy to get, trust in what it produces has to be earned deliberately. Mutation testing, property-based testing, and an independent AI code-review step β€” fresh context, no implementation history β€” are standard parts of how I ship, not afterthoughts.

πŸ’Ό Full-stack: C#/.NET, React/TypeScript, SQL Server

πŸ€– Currently refining a spec-driven, AI-augmented workflow β€” switching deliberately between Claude Code, GitHub Copilot, and Codex, since the field hasn't settled on one right way to do this yet

🌱 Background also spans Python/RAG systems, native Android, and game-engine scripting β€” see below

🌟 Flagship Project

A production ERP system I own end to end, used daily by a 15-person team β€” real-time data visualization, order management, and AI-powered document processing.

  • Tech Stack: TypeScript, React, Vite, ASP.NET Core, Docker
  • Engineering: React Router v7, TanStack Query, SignalR real-time sync; mutation testing (Stryker.NET) and property-based testing (FsCheck/CsCheck) alongside Cypress, Playwright, and Vitest
  • AI Feature: confidence-scored invoice/document extraction agent with human-in-the-loop approval before anything reaches the ledger
  • Status: Production, with full CI/CD and observability (Grafana, Prometheus, Loki, Faro)
  • Related: Backend API | AI Components | Thesis Research
