Gabriel Catimbang

I build web apps and run them.

I’m Gabriel Catimbang, a developer in Naga City, Philippines. I write the app, set up the Linux servers it runs on and wire the pipeline that ships it.

Three years on support chat.

From 2022 to 2025 I answered Bell Canada customers on live chat, one problem at a time, and finished four review periods in the top 10%. It taught me to pin down the problem before I write the fix.

Front end to production.

I take a project from the first screen to the server it runs on, and stay for what breaks after launch.

  1. 01 BuildWeb apps, end to end.

    TypeScript front to back: React, Next.js or TanStack Start on screen, NestJS or Convex behind it. Code the next developer can read without a walkthrough.

    TypeScript · React · Next.js · TanStack Start · Vue & Nuxt · NestJS · Expo & React Native · Shopify storefronts · macOS apps (Electrobun)
  2. 02 ShipPipelines that deploy on their own.

    Docker on Linux servers, GitHub Actions to test, build and deploy every change, and Sentry to say when something breaks.

    Docker · Linux & Nginx · AWS · Cloudflare · Vercel · GitHub Actions · Sentry · Security testing
  3. 03 StoreThe database under the app.

    PostgreSQL with PostGIS for anything on a map, Convex for live data, Redis for the hot path. I pick the store for how the app reads it.

    PostgreSQL & PostGIS · Convex · Prisma · MongoDB · Redis · S3
  4. 04 PlayHackathons, CTFs and games.

    Weekend builds: game engines, AI and capture-the-flag forensics. Stormwatch, flood warnings for Naga City, won AI.DEAS for Impact in 2025.

Where I’ve worked.

Now I’m the DevOps engineer at Detken Development. I moved production off Vercel onto Linux servers we run, cut hosting costs by up to 70% and set up pipelines that test and deploy every change.
