Federated schema, persisted queries and depth limits that stop the obvious attacks.
Developers who work with TypeScript, Go, Redis and take scoped work with a fixed price and delivery date.
Web Application Development
Works with TypeScript, PostgreSQL
A GraphQL gateway with the operational parts finished: schema federation across services, persisted queries so the public surface is a fixed allowlist, depth and complexity limits, per-field authorisation, response caching with correct invalidation, and tracing that shows which subgraph was slow.
Persisted queries
The public surface is an allowlist, which removes an entire class of abuse.
Per-field authorisation
Authorisation at the field, not at the resolver entry point.
Correct cache invalidation
Entity-keyed, so an update invalidates exactly what it should.
Subgraph tracing
Answers "which service made this slow" without guesswork.

API Integration
Works with TypeScript
Source Code
STK push, C2B, B2C and reconciliation, with the callback edge cases already handled.
Script
Build, test, scan, sign and deploy, with caching that actually hits.
API
Issue, send, chase and reconcile invoices over a clean REST API.
Developer Tool
VPC, EKS, RDS, observability and the IAM boundaries, in modules you can read.
Dropped it into a client project, rebranded it, delivered early. The structure made that easy rather than painful.

Nothing abandoned, nothing pinned to a version that was withdrawn. I audited the tree before buying and it held up.

A few things I would have structured differently, but nothing wrong, and it works.

It is a starting point, not a finished product, and it is honest about that. Saved me the boring fortnight.

Billed the saved days to a client at my normal rate. The maths on this one is not complicated.
