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.

Onde os projetos falham

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.

Conformidade

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.

O que construímos

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.

Nosso processo

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.

Perguntas frequentes

Quais linguagens e frameworks vocês usam para desenvolvimento backend?

Trabalhamos principalmente com Node.js e TypeScript — Next.js API routes, tRPC e Express. Para bancos de dados, PostgreSQL via Supabase ou AWS RDS com Drizzle ORM. Escolhemos a ferramenta certa para o trabalho, mas não mudamos de contexto entre seis linguagens diferentes. Expertise profunda em um stack bate conhecimento raso espalhado por muitos.

Vocês conseguem trabalhar com nosso codebase backend existente?

Sim. A maioria dos engajamentos começa com um audit de arquitetura do seu sistema existente. Identificamos débito técnico, gargalos de performance e gaps de segurança, depois propomos correções direcionadas. Não empurramos rewrites quando refatoração resolve o problema. Se um rewrite é genuinamente justificado, vamos mostrar os dados por trás dessa decisão.

Como vocês lidam com autenticação e autorização em SaaS multi-tenant?

Implementamos row-level security em PostgreSQL combinado com políticas RBAC executadas tanto na camada de API quanto de banco de dados. Fluxos de auth usam Supabase Auth ou JWT customizado com refresh token rotation e OAuth/OIDC para enterprise SSO. Todo permission check é centralizado — nunca espalhado por route handlers individuais.

O que inclui seu pipeline CI/CD?

Workflows do GitHub Actions rodam type checking, unit tests, integration tests e linting em cada pull request. Preview deployments funcionam automaticamente em Vercel. Deploys em produção são zero-downtime com rollback automático em caso de falha. Também incluímos dependency scanning, builds de Docker image para serviços AWS e gates de migração de banco de dados.

Vocês oferecem suporte contínuo após o lançamento?

Todo engajamento inclui 30 dias de suporte pós-lançamento cobrindo bug fixes, performance monitoring e ajuda com deployment. Depois disso, oferecemos pacotes de retainer mensal para desenvolvimento contínuo, gerenciamento de infraestrutura e suporte on-call. Documentamos tudo minuciosamente para que seu time interno consiga manter o sistema sem a gente na sala.

Como vocês garantem que o backend aguente alto tráfego?

Desenhamos para escalabilidade horizontal desde o início — API routes stateless, connection pooling, caching Redis e edge deployment. Antes do lançamento, rodamos load tests simulando 10x seu tráfego projetado. Cada endpoint é instrumentado com latency tracking, e alertas disparam em degradação P95 para você pegar problemas antes seus usuários perceberem.
