API & Backend
We build the APIs and services that do the heavy lifting, like the execution layer behind TradePartner that has placed 380,000+ broker orders across Tradier and Schwab. REST and GraphQL endpoints, background jobs, real-time streams, and the integration plumbing most projects get stuck on.
Integrations are where most projects get stuck, so we treat them as a first-class concern. Payment gateways, CRMs, ERPs, shipping providers, identity providers, accounting systems, our team has wired them all into production. We handle the unglamorous parts: retries, idempotency, webhooks, rate limits, and audit logs, so your data stays consistent and your customers stay happy.
Whether you need a brand-new backend for a SaaS product or want to modernize a legacy system one service at a time, we deliver APIs that are well-documented, observable, and built to last.
What we typically build
- REST & GraphQL API design and development
- Third-party integrations (payments, CRMs, ERPs)
- Authentication, authorization, and role-based access
- Database design, indexing, and query tuning
- Background jobs, queues, and scheduled tasks
- Webhooks, rate limiting, and observability
