Tran P.

Senior software engineer with 11+ years building backend systems, distributed architecture, and AI-powered products across commodity trading, fintech, and SaaS.

I specialise in the hard parts: the failing data pipeline under load, the authentication layer that needs to work across a dozen services, the LLM integration that has to stay fast and reliable in production, the architecture decision that will shape everything built on top of it.

I work across the full delivery chain: Python, Kotlin, Go, Java on the backend; Kafka, PostgreSQL, Elasticsearch, and vector databases for data; AWS, GCP, Kubernetes for infrastructure; React, Vue, and Flutter when the frontend needs me. On the AI side, I build with LLM APIs (OpenAI, Anthropic), design RAG pipelines, and integrate AI agents into existing systems where they have to actually work - not just demo well.

I've cut processing time by 40%, designed shared libraries adopted across 8 microservices, and shipped real-time fraud detection systems where latency and accuracy both matter. I bring the same engineering rigour to AI features: production-grade, observable, cost-aware, and built to handle the messy edge cases that break most prototypes.

I operate independently, make critical technical decisions, and treat every system I touch - AI or otherwise - as if I'll be the one maintaining it.
