Full-stack engineer building reliable financial and realtime systems end-to-end — from UI to APIs, data modeling, and operational workflows. I specialize in turning messy, high-constraint domains into deterministic, observable systems. Recently, I shipped a financial reconciliation platform integrating ERP databases, banking APIs (mTLS), XLSX statements, and OCR (AWS Textract) into a structured audit workflow with rerun and traceability controls. I also built a deterministic multiplayer poker engine with realtime sync and LLM-agent orchestration. My focus is design systems with correctness and operability as first principles — ensuring state transitions are predictable, data remains auditable, and production behavior is observable and reproducible under pressure. I’ve worked in structured fintech environments with critical transaction flows as well as product-driven contexts where architectural decisions shape the system from day one. I’m particularly interested in the intersection of deterministic system design and emerging decentralized technologies, having participated in a 6-week Ethereum-focused fellowship in Thailand that deepened my perspective on distributed coordination and cryptographic systems. I enjoy contributing where engineering depth and product thinking meet — whether scaling established platforms or building new ones from scratch.
