$ whoami — senior software engineer · 11+ yrs
I build systems
that survive
production.
Backend in Go, mobile in Flutter and Kotlin. SQLite by default, Postgres tuned when you need it — all running in production somewhere.

Your MVP, shipped
in weeks, not quarters.
Fixed scope. $5k–12k. Async by default. You talk to me, not an account manager.
Performance audit
I measure your stack on your servers, rank the bottlenecks, and fix the quick wins.
- ▸benchmark report you can rerun
- ▸top 5 fixes by $ impact
- ▸infra cost-cut plan
Ship with me
MVP or full product, from schema to deploy. Demo every week, docs your team can run.
- ▸working demo every week

AI Workflow Automation
I find the manual work eating your team's week and automate it with AI agents wired into your tools.
- ▸workflow audit with hours-$ math
- ▸AI agents + integrations, shipped
- ▸team handoff, no new headcount
Things I shipped
that stayed up.
I designed, built, and operated these. They handle real traffic today.
Live streaming without YouTube
One live event: 72K visitors, 126M requests in a day, 11TB served off the edge at 98% cache hit. Go HLS pipeline with adaptive renditions — zero buffering on 360/720.
dripsender.id
WhatsApp marketing automation across 14 servers. Queue, workers, retries — 12,000+ users sending daily.
slug-post
Markdown to shareable web page. No registration, no friction. Live at slugpost.com — powered by laju.
Opinions are cheap.
Benchmarks aren't.
Measured on my own servers. Repro steps are in the repos.
75+ repos. MIT licensed.
Most of them came out of client work — I needed the tool, so I built it.
dulak
Full-stack Bun boilerplate. Auth, uploads, SSR, 6 templates — why my MVPs ship in weeks. Scales vertically on SQLite: single writer, read replicas.
kilat
Edge-native full-stack starter: Hono + D1 + Inertia v3. Free-tier start, migrates to dulak when you outgrow it.
laju
High-performance TypeScript web framework. Powers slugpost.com and klikaja.app in production.
Notes from
real builds.
14 notes on architecture, databases, auth, and deployment — from the dulak docs.
Engineer,
not agency.
11+ years building software — from PHP to Node.js to Go. I work directly with founders and technical teams. No project managers, no status meetings.
20+ projects shipped: queues serving thousands daily, a web framework at 258K RPS, live streaming for 72K visitors in a day, mobile apps in Flutter and Kotlin. If it matters, I bench it before I pick it.
Brief to deploy
in four weeks.
Schema first
Data model + scope lock. No UI until the foundation is right.
Build + demo
Working demo every week. You click it, not read status reports.
Deploy + handoff
Live in production. Docs your team can run without me.
Warranty
14–60 days post-launch support depending on scope.
Timezone Jakarta — how do we communicate?
Async by default, no meetings. Daily written update, demo every week, reply within 24 hours.
Who owns the code?
You. 100% IP handover with docs. 50% upfront, 50% on delivery.
What stack will my MVP run on?
Boring and proven: Go or Bun backend, SQLite default or tuned Postgres, hosted on a $6 VPS or Cloudflare. Benchmarked before picked.
What if I already have a team?
Handoff docs + architecture review included. Or bring me back to automate ops with AI workflows.
