Prasetyo Nugrohadi
Project Lead & Business
Manages delivery, finds the right clients, and makes sure every project stays on track. The person you talk to when you need a straight answer about timelines, scope, or priorities.
LinkedInAbout
The people who build your product.
PT Teknologi Aplikasi Handal Utama is a Jakarta-based technology company. Every client works directly with the people who design, build and run their product.
Why we started
We wanted to build things that matter — on our own terms.
We've seen how software projects go wrong. Clients talk to sales people who disappear after the contract is signed. Requirements get lost between layers of middle management. The people building the product never meet the people using it.
We started Tahu Tech Labs to do things differently. When you hire us, you're hiring the three people on this page — not a company that subcontracts to whoever is available.
Every project we ship carries our names. That is why we are selective about the work we take on, and why we see it through after launch.
The team
You'll know everyone by name.
No org chart needed. Here's who you'll be working with.
Reza Ar Razi
AI Engineer
Deep expertise in machine learning, NLP, and AI systems. Turns ambiguous "we want AI" requests into concrete, production-ready solutions that actually solve the problem.
LinkedIn
Ari Wijaya
Fullstack Engineer
Builds the applications end-to-end — from database schemas and microservice architecture to polished frontends. The generalist who ties everything together.
LinkedInHow we operate
Principles we actually follow.
Honest timelines
If it takes 3 months, we'll say 3 months. We'd rather lose a deal than overpromise and underdeliver.
Show, don't tell
Weekly working demos, not slide decks. You'll see the actual product evolve, not a polished presentation of what it might look like someday.
Say no when we should
If your project needs something outside our expertise, we'll tell you — and help you find the right team instead of faking it.
Code you own
Everything we build is yours. Full source code, documentation, and knowledge transfer. No vendor lock-in, no hostage situations.
