About this gig

Need a complex system built right the first time? Skip the script-builders. Get production-grade architecture from a Senior Software Engineer with 5 years building scalable systems used by 1M+ users across Europe and the US.


I specialize in secure, high-performance full-stack applications and third-party integrations that scale under load.


Engineering Services:

  • Full-Stack Development: React, Next.js, React Native, TypeScript frontends + Node.js, Express, NestJS backends.
  • Advanced API Integrations: Webhooks, REST APIs, GraphQL, and OAuth2 protocols.
  • Async Workflows: Event-driven architectures, background processing, PostgreSQL/MongoDB optimization.
  • Interactive Dashboards: Complex data streams into responsive, clear interfaces.


Why Clients Trust My Code:

  • Zero Technical Debt: Clean, modular TypeScript built for team handover.
  • Enterprise Security: JWT authentication and strict request validation.
  • AI-Accelerated Delivery: I use Claude, Cursor, and Codex to ship faster without cutting corners.
  • Tested Reliability: Playwright, Jest, or Cypress included by default, not as an afterthought.
