Hi, I'mKamil
Full-Stack Engineer
I specialize in Node.js, NestJS, and TypeScript. Designing and developing production systems with a focus on stability, domain consistency, and long-term maintainability.
About Me
Full-Stack Engineer specializing in Node.js, NestJS, and TypeScript. For over 3 years, I've been developing a comprehensive logistics platform operating in EU and non-EU countries. My philosophy: build systems that are transparent, predictable, and free from unnecessary complexity. I prefer modular monoliths, and microservices only when they bring real business value.
Key Impact:
- Established a predictable release process, resulting in 50+ consecutive production deployments with zero rollbacks over the last 12 months
- Designed and optimized a postal code search engine (5M records) with ~30 ms response time per endpoint
- Introduced a modular monolith architecture, enabling safe scaling, refactoring, and future microservice extraction
- Refactored business-critical domains (pricing, VAT, time zones), significantly reducing production risk and development bottlenecks
- Designed and stabilized key external integrations (Stripe, EU VAT validation via VIES, ECB currency rates, geo APIs), supporting operations across EU and non-EU markets
