I'm Joseph — I design and ship end-to-end applications, from the data model up to the last pixel. I care about clarity, performance, and code that ages well.
Selected work
Each project below is something I owned end-to-end — problem framing, architecture, and delivery.
A live, community-sourced electricity-status map for Infanta, Quezon. Volunteer scouts report barangay-level outages while residents watch a real-time map and subscribe to per-barangay push alerts — a Rails 8 Hotwire PWA with an all-database real-time stack and no Redis.
Visit live siteA water-quality monitoring platform that digitizes a local water district's manual pumping-station logs — offline-first field capture, per-station alert thresholds, trend charts, and generated PDF reports. Deployed to AWS with Kamal and CloudWatch alerting.
Visit live siteA voice-of-customer analytics pipeline that scraped and NLP-coded 55,000+ public comments from LANDBANK's 4Ps beneficiaries to pinpoint their #1 pain point — payout timing — then packaged the evidence into a board-ready recommendation. Built in Node.js with a custom lexicon coder for Taglish and Bisaya text.

About
I build software the way I'd want to use it — clear, fast, and honest about its edges.
My work sits at the intersection of engineering and design. I like problems that need both a solid data model and a considered interface, and I care as much about the quiet details — empty states, loading, error copy — as the headline features.
When I'm not building, I'm usually reading about systems design, refining my own tools, or exploring on foot.
