Senior Software EngineerAI/ML, Full-Stack & Distributed Systems
I build AI agents, full-stack products, and automated workflows that hold up in production.
Senior software engineer with 11+ years across AI, full-stack development, and automation. I design LangGraph agents and grounded RAG, and I ship the APIs, interfaces, and workflows that make them dependable.

Since Aug 2026Working on my own business idea
I have a business idea of my own, and I'm working on the plan, the market, and the first steps to turn it into a real business.
Impact
01Selected work
LangGraph agents that route, delegate, and act on business systems safely through MCP.
Access-aware retrieval with hybrid search, reranking, and citations, measured on a fixed evaluation set.
React and FastAPI interfaces that stream answers and tool steps live, with agent runs on async workers.
Evaluation suites and model routing that cut inference cost 28% without lowering quality.
42 deterministic checks across DXF, vector PDF, and scanned drawings, grounded in ASME Y14.5.
LangGraph agents that research, draft, and update CRM records through permission-scoped MCP connectors.
Independently deployable services and Kafka event pipelines sustaining 99.95% availability.
XGBoost with versioned datasets, MLflow tracking, monitored batch inference, and rollback.
Autoscaling and query tuning that cut cloud costs 18%, plus release checks for consistent deploys.
React and TypeScript dashboards, checkout, and subscriptions, with load time cut from 3.2s to 1.4s.
GitHub Actions pipelines with API and UI regression tests, promoting one Docker image to every stage.
Node.js and AngularJS apps for scheduling, customer records, and 40% faster recurring reports.
02Expertise
Agents and retrieval that businesses can trust with real tools and data.
Interfaces and APIs that make complex systems usable and fast.
Repetitive work turned into reliable, observable pipelines.
Services and pipelines designed to stay up, recover cleanly, and scale cost-effectively.
03Experience
Enterprise apps, commerce platforms, event-driven services, and production AI, across on-site, hybrid, and remote teams.

04Skills
Agents that route, delegate, and act on real systems safely, with approvals and audit trails.
Retrieval that cites its sources, measured on fixed evaluation sets before anything ships.
Interfaces and APIs that make complex systems fast and usable, including streaming AI UIs.
Repetitive work turned into reliable, observable pipelines with retries and idempotent actions.
Models taken to production with versioned data, tracked experiments, and safe rollback.
Event-driven services and infrastructure designed to stay up and scale cost-effectively.
05About
Useful AI needs solid software around it.
I've spent more than a decade building software for real businesses, from scheduling and reporting tools to commerce platforms, event-driven services, and, most recently, production AI systems.
My focus is AI that teams can rely on: agents that call real tools safely, retrieval that cites its evidence, and evaluation that catches regressions before customers do. My full-stack and automation background is why I care as much about the API, the interface, and the workflow around the model as about the model itself.
I work with clients worldwide. I'm comfortable working asynchronously, keep people updated without being asked, and can overlap with any time zone when a conversation needs to happen live.
Based in
Bamban, Tarlac, Philippines
Working with teams worldwide, across any time zone.
Fixed evaluation sets and regression suites turn "it seems better" into numbers.
Retries, idempotency keys, checkpoints, and dead-letter queues make recovery routine.
Every tool call and approval leaves a trail that people can review.
Context budgets, model routing, and autoscaling keep quality high and costs in check.
