Backend Development

Backends built for real production traffic

Typed Node.js and NestJS APIs with PostgreSQL or MongoDB, Redis caching, structured logs, and the boring discipline that keeps p95 latency under 100ms.

Why work with me

Most backends are fine on launch day. The question is what happens in month 6 — when traffic is 10× higher, the team has tripled, and the original developer has left. That's the backend I build.

What you get

Everything included in every engagement

No upsells. No surprise change orders. One scope, one price.

Typed REST and GraphQL APIs

End-to-end TypeScript with Zod or class-validator at the boundary, OpenAPI docs, and consistent error handling. Every route is a contract you can lean on.

PostgreSQL & MongoDB done right

Schema design, indexing strategy, migrations, RLS for multi-tenancy, soft deletes, audit logs. Queries that stay sub-100ms past 1M rows.

Caching & rate limiting

Redis for hot data and rate limits, ETags for conditional requests, response compression, connection pooling. Throughput up, infra cost down.

Auth, authz, and security

JWT access + refresh, OAuth, RBAC, API keys, session rotation, OWASP-aware input handling. Done once, done right, audited.

Webhooks & background jobs

Reliable delivery with retry + DLQ, idempotent handlers, BullMQ or Cloud Tasks for async work, cron jobs that you can actually monitor.

Observability built in

Structured logs, request IDs end to end, OpenTelemetry traces, error tracking, and SLO dashboards. You see problems before users do.

Process

How we'll work together

Predictable, written-down, no surprises.

  1. 01

    Architecture review

    Map the data model, identify hot paths, surface scale risks. Output: a written architecture doc you can share with stakeholders.

  2. 02

    Build & test

    TDD-friendly module structure, contract tests against the OpenAPI schema, integration tests against a real DB — not mocks.

  3. 03

    Load & harden

    k6 load tests at projected scale, fix the slowest endpoints first, add caching where it actually moves the needle.

  4. 04

    Ship & monitor

    Blue/green or canary deploys, dashboards for p95 latency and error rate, on-call runbook for the team.

FAQ

Questions I get asked first

Do you work with NestJS specifically, or general Node?+

Both. NestJS is my default for anything past a basic CRUD because of dependency injection and guards/interceptors. Express or Fastify when minimalism matters more.

Can you take over a struggling backend?+

Yes — I do this often. The first deliverable is a written audit covering perf hotspots, security risks, and a prioritised remediation plan before any code is touched.

Do you handle background jobs and queues?+

Yes. BullMQ with Redis, Cloud Tasks, or AWS SQS — picked based on your infra. Always idempotent handlers and a dead-letter strategy.

What about migrations and zero-downtime deploys?+

Migrations are versioned with Prisma or knex/squitch, applied in a separate step from app deploy. Schema changes use expand-then-contract so writes never break.
