Build your product fast, with an AI-powered team
SaaS, mobile apps, Rust software, commerce, and go-to-market apps. I lead every project and you talk to me directly. AI agents do much of the build and trusted partners join when a project needs more hands, which is how we ship fast.
What we build
SaaS
A SaaS built to cost little to run, with the expected monthly bill written into the plan.
See SaaS developmentMobile apps
Mobile apps for your product, built and shipped by the same team that builds everything else.
Rust software
Fast command-line and desktop software, and backends where speed and memory use matter. Public examples: nca and Chaca Scanner.
Read the codeGo-to-market apps
Apps for go-to-market teams: tools that help sales and marketing find, qualify, and reach customers.
Commerce
Online stores and commerce platforms, with payments and checkout tested before launch.
See WooCommerce workAI inside the product
Assistants, agents, and LLM features that run in your product with test cases, logging, and spend caps.
See AI implementationHow we ship fast
AI agents do much of the build
Agents write and test large parts of the code, so a first working version reaches you early.
I lead and own the architecture
One person decides the software, stack, network, and hosting, so the pieces fit together.
Trusted partners when needed
When a project needs more hands, partners I trust join, and I tell you before we start.
Your repo, your code
The work lands in your repository. Under my terms you own the deliverables once you have paid in full.
Built on the stack x.com reports
Our core stack matches what x.com's new web app is reported to use: React, Vite, Fastify, and TypeScript (X engineering report, as covered by iTechPost, 5 November 2026). We also ship Rust and Next.js.
- React
- Vite
- Fastify
- TypeScript
- Rust
- Next.js
Specialist work, booked on its own
You do not need a whole product build. Each of these is a standalone project.
React app improvement
Faster load, smoother screens, and code that is easier to change.
Vite development
Move to Vite for faster builds, or start a new app on it.
Fastify development
Fast, validated Node.js APIs, new or moved from Express.
Database optimization
Slow queries found and fixed, so the database keeps up as data grows.
Clean code for teams and AI
Structure, rules, and checks that developers and AI agents both follow.
Open source you can read
All my client work is under NDA, so the public proof is code. These are the projects I maintain.
nca (native-cli-ai)
A native Rust CLI that orchestrates AI agents across projects, with persistent sessions, git worktrees, and local-first control.
Spec Kit for Cursor
A spec-driven toolkit for Cursor. The /specify, /plan, and /tasks commands turn an idea into specs, plans, and tasks.
Agent Orchestration
An MCP server for multi-agent work, with shared memory, a task queue, and resource locks.
Chaca Scanner
A desktop web security scanner for developers: OWASP Top 10 checks, API exposure, and CMS detection.
RankMySEO
The open-source version of the rank tracker behind rankmyseo.com.
Questions about product engineering
How much does a product build cost?+
It depends on scope. Projects start from $5,000. After a short scoping call you get a written plan with milestones and a quote before any code is written.
Who builds it?+
I lead every project and answer your messages myself. AI agents do much of the build, and trusted partners join when a project needs more hands. I tell you before we start.
Which stack do you use?+
React, Vite, Fastify, and TypeScript, which is also what x.com’s new web app is reported to use, plus Rust where speed matters and Next.js for sites that need server rendering. If your project needs something else, tell me and I say whether I am the right fit.
Do you work with teams outside Indonesia?+
Yes. I am based in Sidoarjo, Indonesia (UTC+7) and work with teams in Europe, Asia, the US, and the Middle East. I work Monday to Saturday, 9:00 to 17:00 WIB, in English or Indonesian, and we set a weekly check-in time during scoping.
Send me your product idea
Tell me what you want to build, who will use it, and when you need it. I reply within 24 hours with questions or a plain answer on whether I am the right fit.
