.
For more than 7 years, I've partnered with startups and enterprise teams to design, build, and scale full-stack systems — though my real specialty is the backend, primarily in Golang and PHP. I've worked on products ranging from email-as-a-service platforms and banking integrations across Southeast Asia to healthcare and e-learning systems serving real users every day.
I'm happiest deep in the backend — creating reliable, high-performance services with clean, maintainable architectures. Whether I'm troubleshooting critical production issues, managing cloud deployments with Kubernetes and AWS, or designing extensible APIs, I aim to build software that scales and lasts. When a project needs it, I'll take it all the way to the frontend too.
Things I've been building
Personal projects
Guesthouse booking system
A full-stack booking platform for a private guesthouse. Guests browse live availability and upload payment receipts, while admins handle pricing, vouchers, and the full reservation lifecycle from one panel.
Reading tracker
A companion app for readers — log reading sessions, build daily streaks, discover your reader persona, and share the books that shaped you.
Where I've worked
Build and maintain backend services in Go and PHP, resolve P0 production incidents, and manage AWS deployments across EC2, ECS, and S3.
Maintained gRPC services for bank transactions, built statement PDF parsers, and onboarded new bank integrations on GCP with Kubernetes and Grafana.
Developed backend services for a platform serving Japanese users and translated Figma designs into polished React UI.
Built EMR and clinic appointment backends, pharmaceutical inventory management, and worked with PhilHealth toward accreditation. Led the development team.
Tools I reach for
Where I can help
From first architecture sketch to production deployment — these are the problems I specialize in solving.
Custom business systems
End-to-end platforms built around how your business actually works — booking systems, POS, EMR, inventory, and internal tools that replace spreadsheets and manual processes.
AI & workflow automation
Put repetitive operations on autopilot — AI-assisted pipelines, document parsing, and smart integrations that quietly save your team hours every week.
API & payment integrations
Reliable integrations with banks, payment providers, and third-party services — clean gRPC and REST contracts that other developers can build on without surprises.
Cloud deployment & reliability
Production-grade deployments on AWS and GCP with Kubernetes, monitoring with Grafana, and incident response — systems that stay fast, observable, and stable.
How I work
Discovery
We map the problem, constraints, and goals so the solution fits how you actually work.
Build
Iterative delivery with clean architecture, tests, and regular check-ins — no black boxes.
Ship & support
Production deployment, monitoring, and handover docs your team can extend confidently.
