8 years taking complex platforms from blank page to production, 4+ years leading engineering teams while staying hands-on, and one of the earliest adopters of AI-native development: I introduced MCP, Claude Code and Cursor company-wide and retrained whole teams around them. Most recently I designed, built and launched a paid iOS finance app solo, from Figma to App Store review.
Equally comfortable architecting AWS infrastructure, untangling production incidents at 2am, and mentoring engineers into leaders.
I'm a Senior Full Stack Lead Engineer with 8 years of experience taking complex platforms from blank page to production, and 4+ years leading engineering teams while staying deeply hands-on.
Twice I was trusted to architect financing platforms from scratch: systems handling real money, where reliability isn't optional. I delivered them with high-availability AWS infrastructure, observability and automated pipelines.
I was one of the earliest adopters of AI-native development in my organizations. I introduced Model Context Protocol, Claude Code and Cursor AI company-wide, wrote the standards and retrained entire teams, fundamentally changing how software gets shipped.
Shipped Cashn't, a paid budget-tracking app live on the Apple App Store, built entirely solo: product design, AI coach, backend API, security, privacy compliance and App Store review. The complete lifecycle most engineers never touch.
Introduced MCP, Claude Code and Cursor AI to entire engineering organizations, wrote the adoption standards and trained the engineers. Companies hiring for AI-readiness get someone who has already led that transition twice.
Twice trusted to architect financing platforms from scratch. Systems handling real money, delivered with high-availability AWS infrastructure, observability and automated pipelines.
Led and mentored 5-engineer teams at three consecutive companies, running disciplined Agile delivery while raising the technical bar through code review, documentation culture and hands-on coaching.
From freelance work as a second-year student to leading five-engineer teams and architecting platforms that process real financial transactions.
Every personal project here was designed, built and deployed by me alone. Five of them run live inside this page: open one, tap around, break it if you can.
A budget tracker that gives you one honest number: what is safe to spend today. With an AI money coach built from your real numbers.
Your stuff. Your people. Nearby. Neighbors give things away, ask for things, borrow things and offer help.
Your school life, all in one place. Schedules, reviewers, flashcards and a class community for Filipino students, with AI that turns photos into timetables and notes into reviewers.
A mobile-first AI image studio driven by photography slash-commands. Pick a photo, type /85mm or /filmgrain, compare before and after, retouch faces on-device.
The dating app where ghosting is impossible. One hour a night, answers before faces, then you both choose: hold or cut.
A warm, motion-rich website for a neighbourhood coffee shop, with a searchable digital menu customers open from a QR code at the counter.
One feed that aggregates LinkedIn, Indeed, JobStreet and Google Jobs, scores every listing against your CV and explains why it matched.
A warm, conversational AI legal companion for Filipinos: explains Philippine law in plain language, relates it to your situation and ends with concrete next steps.
The operations platform behind a multi-account Amazon business: demand forecasting, inventory and shipments, and a keyword "battlefield" command centre with an automated bid engine.
Want to read the code? Every personal project above lives in one place on GitHub, with its README, architecture notes and deployment runbooks. Open a project to see the full list of skills it demonstrates.
All repositories on GitHub ↗Backend, frontend, mobile, cloud, data and AI tooling. Whatever the stack, I pick it up fast and ship it at production quality.
Introducing tools is the easy part. The work is in the standards, the review rules and the training that let a team move fast without lowering the bar.
