Backend, APIs & Integrations
The part users don't see: secure APIs, databases, login, payments and connections to the systems you already use.
What you get
- REST APIs with documentation
- Database design and access rules
- Login, roles and permissions
- Payment flows, including Lao QR (EMVCo) parsing and checks
- Webhooks and third-party integrations
- Realtime updates where the product needs them
How we work
We design the data model and API contract first and agree on it with you. Security is part of the design: least-privilege access, input validation and secrets kept on the server. We often use Supabase and PostgreSQL, Node.js or Python with FastAPI.

Lao QR Parse: Pay & Budget
Parses Lao QR payment codes and turns every scan into automatic budget tracking — see where your money goes without manual entry.
Lao QR Tools
Inspect, edit and regenerate Lao QR (EMVCo) payment codes in your browser: tag tree, CRC check and fix, image decode, and a self-checked QR export.
JWT decoder
Paste a JSON Web Token to read its header, payload and expiry. Decode only — the signature is not verified.
Questions
Can you connect to our existing system?
Usually yes, if it offers an API, a database export or files. We check the options in discovery before promising anything.
Do you work with Lao QR payments?
Yes. We parse and validate EMVCo-based Lao QR codes; try our free Lao QR tool to see it work.
How do you keep APIs secure?
Validated input, authentication on every private endpoint, access rules in the database, and no secret keys in apps or browsers.
