Software Developer
I build backend systems, self-hosted AI infrastructure, and developer tooling. Currently exploring local LLMs and computer vision pipelines on AMD hardware.

00 — Beyond the code
A peek at what I build and break when nobody's watching.
I'm a backend developer by trade, but most of what I build starts with me getting mildly annoyed at something. If a tool feels clunky, expensive, or doesn't exist at all, my instinct is to just build it.
I like practical engineering. Systems that work quietly in the background. Code that solves a real problem without needing a slide deck to explain it.
Outside of work, I play pickleball, push consumer hardware further than it probably wants to go, and rebuild my homelab more often than I should.
Local AI
Running real LLMs on consumer GPUs at home
Homelab & Self-Hosting
Proxmox, Docker, and way too many VMs
Computer Vision
YOLO, OCR, and on-device detection pipelines
Automation
Cron jobs, scripts, and things that fix themselves
Pickleball
Regular games, questionable backhand
Hardware Experimentation
Pushing consumer parts beyond the spec sheet
// pet_projects.built_from_frustration
Side projects born from small daily annoyances. Pick one — the right side cycles on its own.
01 — Projects
Things I've built end-to-end.
Needed a personal site that feels like a developer dashboard, not a corporate landing page.
Challenges
Drivers manually log gas prices and fuel consumption across the Philippines — no easy way to see trends or remember which station was cheapest last week.
Challenges
Tailoring a resume to every job posting is tedious and error-prone. Generic resumes get filtered out.
Challenges
Windows has no per-process VRAM tool for AMD GPUs. Task Manager shows only the total; AMD Adrenalin shows only the total.
Challenges
02 — Infrastructure
Self-hosted across a Proxmox box at home and a cloud VPS.
03 — AI Lab
Local inference and computer vision experiments.
04 — Experience
Where I've been and what I've shipped.
Backend dev, internal tooling.
Gonna — social media platform for businesses.
Angebot — drag-and-drop document builder for sharing and signing documents between businesses.
ChargeHeroes — Airbnb-like rental platform for vacant EV chargers. Acquired by a competitor a year later.
Ment v2 — platform for parents with children who have ADHD and mental disabilities.
Platform-based project for a client in Australia.
Self-hosted inference + image gen.
Started Re-Fuel price-board detection.
05 — Now
Active threads. Updated as things ship.
multi-backend proxy + embedding server
end-to-end, beyond the Re-Fuel MVP
HIP-native builds, draft-model speculation
06 — Contact
Open to interesting backend, infra, and AI work.
