About

Development is my hobby, profession, and daily practice.

I’m a software developer whose free time and work both revolve around building software and working with computer technologies. My recent work includes a complete NFC Digital Business Card SaaS application with secure auth, analytics, payments, and CRM integrations.

I use AI-assisted tools judiciously for boilerplate, documentation, and test scaffolding — maintaining full ownership of architecture, security, and code quality.

Highlights

  • 100+ RESTful PHP API endpoints with secure JWT and MFA.
  • 50+ Angular standalone components with clean state management.
  • 15+ MySQL tables with indexing, FK constraints, and analytics queries.
  • Stripe subscription lifecycle, webhooks, idempotency, and receipts.
  • Integrations with HubSpot CRM, Gmail API (OAuth 2.0), Apple Wallet (.pkpass).
