Software Development Studio
Tools that fit the hand.
We build software that follows how people actually work — handling everything from framing the problem to design, implementation, and running it in production. Ship something small, then learn from real use.
Services
What we do
Not just building — deciding what to build, and keeping it alive after launch.
Product Development
Design and implementation of web applications and internal systems, from technology choices through to production operations.
AI Enablement
Putting generative AI to work: RAG and agent design, from first prototype to something that holds up in production.
Technical Advisory
Architecture reviews, development process, code review. We stay alongside your team until they can carry it themselves.
Products
What we build
Alongside client work, we build and run our own services.
Japanese postal code search
Address Engine JP
Search Japanese addresses from either direction: type a postal code to get the address, or type a town or municipality name to find the postal code. Suggestions appear as you type.
- Postal code to address lookup
- Reverse lookup from town and municipality names
- Public REST API (GET /api/v1/postal-codes/{code})
Data source: Japan Post "Postal Code Data (KEN_ALL)"
Approach
How we work
Decide what to build, together
Come to us before the requirements are settled. We start by working out what the real problem is and where to cut in first.
Build small, verify early
We hand over something working as early as possible and adjust direction from real use — which structurally reduces expensive rework.
Write code that can be handed over
Documentation, tests, and CI/CD ship with the code. The goal is a codebase your team can keep moving without us.
Tell us what you are working on.
A rough idea is enough — it does not have to be a spec yet. A second opinion on a technology decision is also welcome.
