We build & ship full products.
End to end — mobile, backend, cloud, AI and payments. Senior engineering that ships fast, with one point of contact from idea to a running app.
Start a project →Everything a product needs — under one roof.
Like a black hole, we pull every part of your product into one orbit — the app your users touch, the API behind it, the cloud it runs on, and the hard parts in between. Most freelancers hand you a piece; we own the whole slice.
Mobile apps
Flutter for iOS & Android from one codebase — native feel, offline-aware, shipped to the stores (or sideloaded for testing).
Backend & APIs
Go services on Supabase/PostgreSQL — scalable, secure, and properly tested, with your data handled safely by default.
Cloud & infra
Cloudflare Workers and edge deploys, CI pipelines, backups and observability — so it stays up and stays fast.
AI & payments
LLM and OCR features and real payment flows (cards, PromptPay, LINE) — wired in properly, not bolted on.
Broad, with a sharp edge.
Strongest in the first row — and we adapt to your stack for the rest. The real specialty isn't a language: it's shipping complete, secure products, fast.
Shipped, not slideware.
Real products taken end to end. Public ones link out; private client apps show the shape of the work only.
