Experience
- Built a 3-agent orchestration system on OpenClaw — manager, researcher, and builder agents coordinating autonomously via session tools with human approval gates at every handoff.
- Designed and deployed a custom RAG server in Rust with LanceDB, Gemini Embedding 2 (multimodal), hybrid search (vector + BM25), Weibull decay, noise filtering, and per-page PDF ingestion.
- Integrated Gmail automation (OAuth2, Pub/Sub push notifications, programmatic send/read/watch) and multi-platform messaging (Telegram, Discord) with channel-based agent routing.
- Built Sharingan, a zero-shot vision system using SigLIP2 on CUDA with REST API, enabling real-time image classification for security monitoring.
- Developed an autonomous LinkedIn outreach agent automating personalized connection requests and follow-up messaging with human-in-the-loop quality control, integrated with Slack and email.
- Designed a Sales Agent SaaS using LangGraph — orchestrating multi-agent workflows with Agentic RAG for product knowledge, persistent memory, human-in-the-loop handoff, and Facebook Messenger integration.
- Designed an agentic chatbot using LangGraph with database querying, local document processing, code execution, and internet access capabilities.
- Created Selenium-based automated allocation tool, eliminating 98% of manual planning and saving 3 days/week for planners across Philippines and Thailand.
- Implemented a RAG chatbot for technical information retrieval, improving efficiency in equipment repairs and technical reviews.
- Developed test solutions for Simultaneous Sampling SAR ADC converters (characterization to manufacturing). Built LGBM model to predict parameter shifts under temperature, optimizing test time.
Graduated cum laude. Licensed Electronics Engineer.
