Software engineer and solution builder. I ship end-to-end products — web apps, iOS apps, AI apps, and developer tools — for the problems I want solved myself.
Philippine financial independence planner for iPhone
Offline-first planner that estimates when your savings and investments may support the life you want. Built around Philippine vehicles like MP2, PERA, RTBs, SSS, and GSIS. No accounts, no cloud sync, no tracking.
AI workflow analyzer with research-backed criteria and exportable build specs
Describe any business process — sajj decomposes it into steps, scores each against four boolean criteria (structured, deterministic, low-risk, no authority), and generates a full build spec you can paste into Claude Code or Cursor. Free, no signup, feeds graduate research on AI-human workflow boundaries at AIM.
I'm curious about how things work — industries, systems, people's workflows. When I spot a real problem, I build the full thing that solves it. That's led me to ship web apps, iOS apps, AI apps, and developer tools — things I need myself first, then release when they're solid.
My background spans fund accounting, financial software support, and software engineering. I've seen systems from every angle — as the user processing transactions, as support debugging issues, and as the developer building the infrastructure. That perspective shapes how I think about problems, and it's why I trust specifics over abstractions.
Right now I'm working on developer experience (pyworks.nvim), personal finance software for Filipinos (Namna), and how AI can improve workflows in regulated industries. I'm also pursuing a Master's in Innovation and Business at AIM.
Curious about new industries and the problems people are solving. If you're building something that could use an experienced engineer — full-stack, mobile, or AI-adjacent — let's talk →

I built a Neovim plugin for Obsidian as a thin wrapper over Obsidian's official CLI — not a Lua reimplementation of the vault format....
I've been getting the 'can AI handle my workflow?' question enough times to want a serious answer. So I built a free tool that...
I take on a small number of consulting and solution-building engagements each quarter. Whether you're shipping a product, rebuilding a system, or exploring an idea that needs an experienced hand — tell me what you're working on.
