I build things across the entire stack: web apps, desktop apps, backend services, whatever the problem calls for. My daily toolkit revolves around TypeScript, React, Next.js, Vite, and Node.js, but I also ship Electron apps, wrestle with Java microservices at my day job (Spring Boot pays the bills and it's honestly pretty fun), and constantly explore new tech just because I can.

Lately, I've been actively harnessing AI workflows to level up how I execute, less about doing more, more about doing it better. When I clock out, I go full goblin mode on my homelab infrastructure: managing cluster orchestration on PVE, running my self-hosted Hermes Agent, routing traffic through Tailscale and Cloudflare tunnels, and self-hosting my own databases, personal apps, and services because public cloud pricing gives me existential anxiety.

TLDR; I just really like making computers do things :D

Jamutify

Spotify Wrapped gives you stats. Jamutify gives you drinkable recipes based on your music taste. I built an apothecary-themed web app that turns your top Spotify artists and tracks into personalized Indonesian Jamu herbal tonic recipes, generated by AI and exportable as 9:16 recipe cards for Instagram Stories.

Linen

A minimalist Tauri 2.0 desktop Markdown editor with real-time split preview, WYSIWYG toggle, Mermaid diagrams, and KaTeX math. Built because Notepad++ wasn't cutting it for the 50+ .md files scattered across my homelab docs.

Sutura

I needed to translate an entire Chinese codebase to English's UI strings without breaking AST structures. Sutura parses 44 file types through Tree-sitter, feeds extracted strings to AI models (Gemini, Claude, GPT, DeepSeek, or local LLMs), and surgically injects translations back at the byte level, no broken syntax, no regex tears.

Receiptify Got Me Thinking: What If Your Spotify Data Generated Drinkable Recipes?

Receiptify turns your Spotify data into a receipt. I took that idea, asked "what if the output was drinkable," and built Jamutify, an AI apothecary that generates real Indonesian Jamu herbal recipes from your music taste, complete with sonic reasons, QR codes, and Instagram-ready recipe cards.

Encrypting Secrets at the Database Layer: pgcrypto, Prisma Extensions, and Why I Trust PostgreSQL with My Keys

I built a private secrets vault where encryption happens inside PostgreSQL itself, not in my Next.js app. Here is how pgcrypto, Prisma client extensions, and a single env var came together, plus the trade-offs I accepted along the way.

Desktop Apps Are Just Websites with Extra Steps (and That's Fine)

Honest comparison of Tauri and Electron from someone who built real desktop apps with both. Spoiler: they're both web wrappers, and that's okay.

Currently open to full-time, part-time, or freelance work, but you don't need a project in mind to say hi. I work across the full stack: web apps, desktop apps, backend, infra, whatever the problem calls for. Extra points if it's something weird or unconventional; give me a strange problem and I'll probably enjoy it more than a normal one.
So if you need something built (or fixed, or self-hosted), let's talk. And if you just want to chat, swap ideas, or make a new internet friend, that works too~
I'm always happy to connect (｡•̀ᴗ-)✧
