I build scalable, high-performance web applications with a focus on clean code, smooth UX, and solid testing.
From GIS mapping platforms and cybersecurity tools to high-frequency trading (HFT) applications and backend services in Go, I thrive on solving complex problems and delivering impactful products.
- Frontend wizardry with React, TypeScript, and modern tooling
- Creating robust test suites (Unit, Integration, E2E) with Jest, Testing Library, Playwright
- Designing scalable architectures and clean component patterns
- Golang backend development — gRPC/HTTP APIs, PostgreSQL integration
- Quick to adapt and learn — I pick up new tech stacks
- Frontend: React.js, TypeScript, JavaScript, HTML, CSS/SCSS
- Backend: Go (gRPC, Chi, PostgreSQL, SQLite), Node.js
- Testing: Jest, Testing Library React, Playwright
- Databases: PostgreSQL, SQLite
- DevOps: Docker
- Methodologies: Agile / Scrum
- 🗺️ GIS Platform — Map-heavy, data-rich interfaces for geo-data visualization
- 🛡 Cybersecurity Tools — Contributed to unit & e2e testing with Jest, Testing Library, and Playwright
- ⚡ High-Frequency Trading App — Performance-focused frontend with extreme optimization requirements
- 🔑 GophKeeper (learning project) — Secure client-server password & secret manager in Go with TLS authentication
- 🔗 URL Shortener (learning project) — Go-based service with JWT auth, gRPC & HTTP servers, PostgreSQL storage, and background workers — built to deepen my backend architecture skills
I debug better after coffee and cookies — sugar seems to boost both my patience and my console.log test skills 🍪☕.
