Services
What our engineers take on.
Backend work for product teams and IT services firms, by engineers who join your team for weeks or months.
APIs and backend services
New services and REST APIs, or new features on the ones you already run.
- API design and documentation that your front end and your partners can build on.
- Background jobs, queues, and integrations with third-party APIs.
- Tests with every change, so the next person can change it safely.
Taking over a codebase
An application someone else built, with little documentation and few tests.
- We read it, map it, and tell you what is risky before we change anything.
- We add tests around the parts we touch.
- We keep shipping features while the codebase gets steadier.
Speed and scale
Pages, endpoints or jobs that got slow as the data grew.
- We measure first: profiling, query plans and logs.
- Then we fix the cause: queries, indexes, caching or how the data is read.
- One example: a reporting query cut from over 25 seconds to under 1 second.
Payment features
Card and payment features, where a mistake costs real money.
- Disputes and chargebacks, with their stages and deadlines.
- Reconciliation of settlement files against your own records.
- Billing, fees and reports that your finance team can check.
AI integrations
Making your product usable by AI agents, and using AI tools without lowering the bar.
- Connectors and SDKs that let AI agents use your existing API.
- AI-assisted development, with tests and code review on every change.
- Plain answers about where AI helps in your codebase and where it does not.
Stack
What we know best
Python, Django, FastAPI, Django REST Framework, SQLAlchemy, PostgreSQL, MySQL, Redis, Docker, AWS
Each profile lists the engineer's own stack. If yours is not here, ask anyway: we tell you in the first reply whether we can staff it.

We reply by email with an NDA and the profiles that fit.
