What I'm looking for

I’m looking to build and lead production systems in fintech and applied AI—owning architecture end-to-end, shipping secure services, and collaborating across product, compliance, and ML to deliver measurable impact.

I’m a fintech and applied AI-focused technology leader who sets and executes product-aligned roadmaps—balancing compliance needs with real-world innovation. As Vice President of Technology at Buckyy, I architected the core AI-driven risk scoring platform (Rini) and credit workflow, reducing manual underwriting dependencies by 50% while improving API throughput by 30% through architecture and caching optimizations.

I design and ship production systems end-to-end, from backend architectures (FastAPI, PostgreSQL, REST APIs, JWT/RBAC, microservices) to frontend and mobile delivery that’s deployed to the Play Store and App Store. Previously, I led Rini’s XGBoost credit scoring model work, improving prediction stability by 12–15% through feature engineering and retraining, and I’ve built cross-platform products like Lifestory using Flutter + Vue—while mentoring engineers and standardizing CI/CD to reduce deployment errors.
