👨‍💻 About Me

Fullstack developer with 5+ years of experience building high-complexity, production-grade systems across fintech, telecommunications, financial compliance (AML/KYC) and B2B SaaS.

I specialize in designing scalable backend architectures (microservices, event-driven, CQRS) and crafting modern frontend interfaces with React and Angular. As a Squad Lead, I drive engineering standards, structured code reviews, pair programming and team mentoring.

I apply TDD, DDD and Clean Architecture daily, with a proven track record of full end-to-end delivery — from architectural design to production deployment.

  • 🏦 Built platforms handling 25M+ billed SMS/month for 100+ clients
  • 🎓 Architected a B2B LMS platform supporting hundreds of concurrent learners
  • 🔐 Designed AML/KYC compliance systems with multi-domain modular architecture
  • 🧪 Strong advocate for testing, observability and engineering excellence
