API & Backend Engineering
APIs that scale,
backends that never fail
We design and build robust, high‑performance server architectures that power your mobile apps, SaaS platforms, and AI integrations. Clean contracts, zero downtime, and developer‑friendly documentation.
How We Engineer
Backends built on engineering fundamentals
No shortcuts, no spaghetti code. Just battle‑tested patterns that keep your business logic clean and your APIs a joy to consume.
API‑First Design
We design the contract before writing a single line of code. OpenAPI specs, auto‑generated SDKs, and clear versioning – your frontend team can start in parallel.
Performance at Scale
Sub‑100ms response times, connection pooling, query optimisation, and aggressive caching. Your backend handles 10x traffic without a yawn.
Modular & Maintainable
Clean architecture, separation of concerns, and exhaustive test coverage. Future you (or any new developer) will thank us.
Security First
OAuth 2.0, JWT, rate limiting, SQL injection prevention, CORS, and data encryption – all baked in from day one. SOC 2 / ISO 27001 ready.
Observability Built‑In
Structured logging, metrics, and tracing with OpenTelemetry. You'll know exactly what's happening – before your users do.
Event‑Driven Architecture
When monolithic isn't enough, we design message queues, event buses, and Webhook infrastructures that decouple services and increase resilience.
Deliverables
What we hand over
A complete backend package – not just code, but the tests, docs, and runbooks your team needs to own it in production.

The engines we choose
We don’t believe in one‑size‑fits‑all. The stack is decided after understanding your scale, team, and long‑term roadmap.

Our Process
From whiteboard to production
A structured lifecycle that guarantees on‑time delivery, zero scope creep, and a codebase you’ll actually enjoy inheriting.
01
Discovery & Tech Audit
We understand your data models, third‑party integrations, and performance expectations. Existing codebase? We'll audit it first.
02
Architecture Blueprint
API design, database schema, and infrastructure diagram – reviewed and signed off. No ambiguity, no surprises.
03
Incremental Builds
We deliver working endpoints weekly. Postman collections, Swagger docs, and test suites grow alongside the code.
04
Performance & Security Hardening
Load testing, penetration testing, query optimisation, and caching strategies. We break it on purpose, then fix it.
05
Handover & Documentation
Complete API reference, architecture decision records, runbooks, and a recorded walkthrough for your team.
06
Support & Evolution
We monitor, patch, and optimise post‑launch. New microservice? We'll design it to fit the ecosystem without breaking anything.
Our core stack is Node.js (Express / Nest.js) and PostgreSQL, but we also deliver production systems in Python (FastAPI / Django), Go, and PHP (Laravel). We choose based on your use case – not our comfort zone.
Yes, when the scale demands it. We also modernise monoliths into services incrementally – no risky big‑bang rewrites. We'll help you decide what actually needs to be distributed.
We design for sub‑200ms p95 latency using connection pooling, query optimisations, Redis caching, and CDN‑edge where appropriate. Every endpoint is load‑tested with k6 before handover.
Absolutely. From normalisation and indexing strategies to migration scripts and read‑replica setup – we treat the database as a first‑class citizen, not an afterthought.
Every project includes an auto‑generated Swagger/OpenAPI document, a Postman collection with example requests, and a human‑readable wiki covering authentication flows, error codes, and rate limits.
We've connected hundreds of third‑party APIs – payment gateways, CRMs, ERPs, legacy SOAP services. If there's documentation, we'll integrate it. If there's not, we'll reverse‑engineer it.
