I’m a Founding Engineer at SoraNova, building AI knowledge platforms from the ground up. My work sits at the intersection of production LLM systems, cloud infrastructure, and full-stack development.
Previously I was an AI Engineer at Espressif Systems, and a Graduate Research Assistant at NUS where I published a Best Paper Award-winning paper at IROS 2021.
Experience
Founding Engineer — SoraNova (Jun 2024 – Present, Singapore)
- Architected and built an entire AI knowledge platform from scratch — 159k net lines across 1,272 commits spanning a FastAPI backend, multi-agent AI workflows, and React frontend
- Engineered a production RAG system with hybrid retrieval (PostgreSQL pgvector + keyword), improving answer relevance 25% through semantic search and query caching
- Designed a multi-agent research system orchestrating 5 specialised LLM agents (factual, technical, market, team, risk) for comprehensive VC investment research reports
- Implemented ML evaluation framework with DeepEval — 15+ metrics across completeness, accuracy, relevance, and quality
- Owned complete DevOps pipeline: GitHub Actions CI/CD, Docker multi-stage builds, Packer GPU AMI workflows (T4/L4/A100), Ansible, and Harbor container registry
AI Engineer — Espressif Systems (Sep 2022 – May 2024, Singapore)
- Implemented ML algorithms (Graph Neural Networks, RL, Bayesian Optimisation, Simulated Annealing) for chip design, saving 20% time vs. manual baseline
- Developed AI evaluation framework across 175+ Verilog benchmarks using Pass@K, BLEU, and Levenshtein metrics
- Managed distributed RL training infrastructure with 8× NVIDIA GPUs
Graduate Research Assistant — NUS (Aug 2020 – Aug 2022, Singapore)
- Applied deep RL to real-world robotic applications, outperforming classical control baselines
- Published paper at IROS 2021 — Best Paper Award
