Software Engineer — backend-focused, comfortable across frontend and infrastructure.
I like building software where state, persistence, failure handling, reliability, and system behavior matter—not just wiring frameworks together. My strongest interest is backend engineering, with growing depth in distributed systems, databases, infrastructure, platform engineering, and applied AI.

| Project | What it is | Engineering highlights | Stack |
|---|---|---|---|
| Wago | Lightweight self-hosted WhatsApp gateway for integrating one account with an existing backend. | Durable outbound state, idempotency, signed webhooks with retry/recovery, separated human/machine auth, health/readiness checks. | TypeScript, React, SQLite, Docker |
| Notespace | Self-hosted knowledge workspace for notes, spatial thinking, and deliberate study. | Serialized/versioned autosave, conflict handling, cross-tab Canvas reconciliation, full-text search, transactional backup/restore. | Go, React, TypeScript, SQLite |
| SOPFlow FTI | Workflow system for managing SOP documents from authoring through approval and signing. | NestJS workflow backend, MariaDB migrations, production bootstrap flow, SSE notifications, personal P12/PDF signing, Docker deployment. | NestJS, React, TypeScript, MariaDB, Prisma, Docker |
| Chatspace | Chromium extension that turns rendered ChatGPT conversations into a zoomable branch-aware canvas. | DOM → logical turn graph projection, stable message identity, branch persistence, streaming updates, privacy-conscious local metadata. | TypeScript, React, Chromium Extension |
| Minang Language | Small programming language and interpreter using Minang-language keywords. | Lexer → parser → AST → interpreter pipeline, REPL, control flow, functions, recursion, language-level error handling. | C++17 |
Deepening backend and systems engineering: distributed systems, networking, databases, cloud/infrastructure, platform engineering, reliability, performance, and production engineering.
