About yellowflash.dev
An Indonesian software development agency focused on custom development — not templates, not install-only tools.
Quick Profile
yellowflash.dev is a software development agency based in Bintaro, South Tangerang. We serve local SMEs across Greater Jakarta as well as national startups & corporates, with projects ranging from IDR 5M to IDR 300M.
A small, focused, opinionated team — we believe engineering rigor matters more than service bundling. Every project is handled directly by the founder for technical decisions, with modern tooling support (Claude Code Max) for velocity.
Founder
Andhika Bayu Permana
Founder & Lead Engineer
Full-stack engineer with 5+ years of web and mobile development experience. Specialist in Laravel, CodeIgniter 4, Next.js, React Native, and native Android/iOS. Has handled projects from SME landing pages to multi-branch enterprise information systems.
Philosophy: clean, maintainable custom code beats a fancy stack with vendor lock-in. Transparent pricing beats hidden bundling.

Values & How We Work
- Custom from scratch — we don't resell themes or install plugins. Every project is engineered for the client's specific needs.
- Transparent pricing — the IDR 5–300M range is openly published on the pricing page.
- 6-month bug warranty — the industry norm is 1–3 months. We offer 6 because we trust the quality we ship.
- Client owns the source code — full handover, no vendor lock-in.
- SEO-ready by default — schema markup, sitemap, robots, Core Web Vitals — not an upsell.
