Experience

Current
Agent Developer
Arkpad · Makati, Philippines · Jun 2024 – Present
  • 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.
AI Engineer
TresCivil · New South Wales, Australia · Dec 2023 – Mar 2024
  • Designed an agentic chatbot using LangGraph with database querying, local document processing, code execution, and internet access capabilities.
Manufacturing Engineer for Data Science
Analog Devices, Inc · General Trias, Cavite · Jan 2022 – Mar 2024
  • 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.
Test Development Engineer
Analog Devices, Inc · General Trias, Cavite · Nov 2019 – Jan 2022
