What Are Backend Development Services?

Backend development is the server-side work that actually powers your application — API design, database modeling, authentication, authorization, observability, and deployment infrastructure. For SaaS startups and enterprise teams, that means building systems that handle real traffic, scale without drama, and don't turn into a nightmare as your team grows. We ship production-grade backends on Vercel and AWS with fully automated CI/CD pipelines.

Dónde fallan los proyectos

Your API slows to a crawl under moderate traffic Users leave before your product gets traction. Investors start noticing the retention graphs.
Database queries fall apart once you push past 1M rows Unindexed joins and missing query plans create slowdowns that get exponentially worse — and you can't patch your way out of them.
Auth was bolted on with JWT hacks and role checks scattered across controllers One misconfigured middleware and customer data is exposed. A breach at seed stage can end the company.
Without observability, you find out about outages from support tickets Resolution takes hours. Every incident erodes the trust you've been building with enterprise customers.
Deployments are manual, untested, and stressful Nobody wants to push on a Friday. Features pile up in staging while competitors ship every week.
Your backend was prototyped by a full-stack generalist and it shows Technical debt compounds with every new feature. A rewrite at Series A costs 3–5x what it would've cost to build it properly the first time.

Cumplimiento

API Design & Validation

RESTful and tRPC APIs with Zod schema validation at every boundary. Type-safe from database to client — no runtime surprises.

Database Architecture

PostgreSQL schema design with proper indexing, migrations, and query optimization. We use Drizzle ORM for type-safe queries and Supabase for managed infrastructure.

Auth & Authorization

Row-level security, RBAC, and OAuth/OIDC flows that actually work. Built on Supabase Auth or custom JWT with refresh token rotation.

Observability Stack

Structured logging, distributed tracing, and alerting configured from day one. Datadog, Sentry, or OpenTelemetry — set up properly, not just installed and forgotten.

CI/CD Pipelines

GitHub Actions workflows with preview deployments, automated testing, and zero-downtime production deploys on Vercel and AWS.

Security Hardening

Rate limiting, input sanitization, CORS policies, and dependency scanning baked into the pipeline. SOC 2-ready patterns from the start.

Qué construimos

Edge-Ready API Routes

Next.js API routes and serverless functions deployed to Vercel's edge network for sub-100ms response times globally.

Database Migrations

Version-controlled schema migrations with Drizzle Kit — reversible, auditable, and CI-gated before they touch production.

Multi-Tenant Architecture

Row-level security and tenant isolation patterns that let you onboard enterprise customers without forking your codebase.

Background Job Processing

Queued tasks for email, webhooks, and data pipelines using Inngest, BullMQ, or AWS SQS — with retry logic and dead-letter handling built in.

Rate Limiting & Caching

Redis-backed rate limiting and response caching that protects your API and cuts infrastructure costs when traffic spikes.

Infrastructure as Code

AWS CDK or SST configurations checked into your repo — reproducible environments that any engineer on your team can actually deploy.

Nuestro proceso

01

Architecture Audit

We review your existing backend (or your requirements doc), map out data flows, find the bottlenecks, and produce a technical spec with schema diagrams and API contracts.
Week 1
02

Database & API Foundation

Schema design, migration setup, core API routes, and auth flows. You get a working backend with tests passing in CI by the end of this phase.
Weeks 2-3
03

Feature Build & Integration

Business logic, third-party integrations, background jobs, and webhook handlers. Daily deploys to preview environments so your team can test against real builds.
Weeks 4-6
04

Observability & Hardening

Logging, tracing, alerting, rate limiting, and load testing. We simulate traffic spikes and verify your system holds up at 10x your projected load.
Week 7
05

Launch & Handoff

Production deployment, runbook documentation, and a 30-day support window. Your team gets a recorded walkthrough of everything we built.

Preguntas frecuentes

What languages and frameworks do you use for backend development?

We work primarily in Node.js and TypeScript — Next.js API routes, tRPC, and Express. For databases, PostgreSQL via Supabase or AWS RDS with Drizzle ORM. We pick the right tool for the job, but we don't context-switch across six languages. Deep expertise in one stack beats shallow knowledge spread thin across many.

Can you work with our existing backend codebase?

Yes. Most engagements start with an architecture audit of your existing system. We identify technical debt, performance bottlenecks, and security gaps, then propose targeted fixes. We don't push rewrites when refactoring will do the job. If a rewrite is genuinely warranted, we'll show you the data behind that call.

How do you handle authentication and authorization for multi-tenant SaaS?

We implement row-level security in PostgreSQL combined with RBAC policies enforced at both the API and database layers. Auth flows use Supabase Auth or custom JWT with refresh token rotation and OAuth/OIDC for enterprise SSO. Every permission check is centralized — never scattered across individual route handlers.

What does your CI/CD pipeline include?

GitHub Actions workflows run type checking, unit tests, integration tests, and linting on every pull request. Preview deployments spin up automatically on Vercel. Production deploys are zero-downtime with automatic rollback on failure. We also include dependency scanning, Docker image builds for AWS services, and database migration gates.

Do you provide ongoing support after launch?

Every engagement includes 30 days of post-launch support covering bug fixes, performance monitoring, and deployment help. After that, we offer monthly retainer packages for ongoing development, infrastructure management, and on-call support. We document everything thoroughly so your internal team can maintain the system without us in the room.

How do you ensure the backend can handle high traffic?

We design for horizontal scalability from the start — stateless API routes, connection pooling, Redis caching, and edge deployment. Before launch, we run load tests simulating 10x your projected traffic. Every endpoint is instrumented with latency tracking, and alerts fire on P95 degradation so you catch problems before your users do.
