What I'm looking for

I’m looking for a FinTech role where I can lead backend/API modernization, improve performance for high-throughput systems, mentor engineers, and build maintainable services using Python/FastAPI and AWS.

I’m a Tech Lead and Senior Software Developer focused on building and modernizing high-impact FinTech backend platforms. I’ve led core-module development for Markets Mojo products, driving innovation across electronic trading systems.

I spearheaded the migration of critical PHP modules to Python using FastAPI. I designed scalable backend APIs, including Webhooks and WhatsApp integrations, enabling real-time client communication and stronger engagement.

I’m passionate about clean architecture, code optimization, and delivering maintainable, high-performance systems. I also emphasize coding standards and quality through team mentorship and continuous improvement.

Across multiple roles, I’ve delivered enterprise-grade solutions and complex integrations, working with secure financial applications, reporting, and compliance modules. I’ve improved performance in high-traffic features using Redis caching strategies and built reliable API-driven experiences.
