Backend & APIs
Business logic engineered for reliability and change.
We design and build secure, contract-first backend APIs and distributed systems. Our backend architecture prioritizes data integrity, auditability, performance, and clean integration boundaries.
Why this exists
The problem it solves
Stalled APIs, brittle third-party integrations, and unindexed database queries create performance bottlenecks that compromise backend security.
Modern software relies heavily on clean API contracts, background worker queues, and robust auth models to support web and mobile frontends.
Written scope
What is in scope, and what is not
Slow database queries, fragile API integrations, security gaps in auth, and background jobs crashing without logs.
- SaaS platforms needing typed REST or GraphQL APIs
- Applications scaling database schemas and user permission models
- Products requiring asynchronous background job queues and webhooks
- Unsubstantiated claims of handling 'billions of requests' without real traffic requirements
- Typed API routes & Zod validation
- Database migrations & indexes
- Auth & RBAC middleware
- Webhook handlers
- Third-party API subscription costs (Stripe fees, SMS gateway costs, etc.)
- Data entity requirements
- Third-party API credentials
- Business logic rules
- Security requirements
- Number of entity models and endpoints
- Complexity of RBAC permissions and background jobs
