Expert at navigating the "zero-to-one" phase, specialising in transforming ambiguous product requirements into robust, high-performance distributed systems that serve as the backbone for scaling startups.

Driven by a hybrid mindset, I balance deep technical execution with high-level architectural influence. I am focused on building secure, resilient, and developer-friendly infrastructure, ensuring that every line of code contributes to a scalable foundation for long-term growth.

  • Develop sophisticated data schemas and optimize database performance to ensure data integrity and system responsiveness under heavy load.

  • Lead the integration of third-party security protocols and internal identity management systems, maintaining a "security-first" approach to development.

  • Ship high-quality, production-ready code in rapid iteration cycles, consistently meeting aggressive milestones without compromising on system stability.

  • Influence the technical roadmap by identifying architectural bottlenecks and proposing modern, cost-effective solutions to improve system throughput.

  • Collaborate across the engineering team to establish best practices for testing, CI/CD, and asynchronous documentation.
