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.

项目失败的原因

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.

合规

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.

我们构建的内容

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.

我们的流程

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.

常见问题

您在后端开发中使用哪些编程语言和框架?

我们主要使用 Node.js 和 TypeScript — Next.js API routes、tRPC 和 Express。对于数据库,我们使用通过 Supabase 或 AWS RDS 的 PostgreSQL,搭配 Drizzle ORM。我们会为工作选择合适的工具,但不会在六种语言之间频繁切换。深入掌握一个技术栈胜过在众多技术上知识浅薄。

您能否与我们现有的后端代码库协作?

可以。大多数合作都从审计您现有系统的架构开始。我们识别技术债务、性能瓶颈和安全漏洞,然后提出有针对性的修复方案。当重构就能解决问题时,我们不会推动完全重写。如果确实需要重写,我们会向您展示支持这一决定的数据。

您如何为多租户 SaaS 处理身份验证和授权?

我们在 PostgreSQL 中实现行级安全性,并结合在 API 和数据库层都强制执行的基于角色的访问控制策略。身份验证流程使用 Supabase Auth 或自定义 JWT,配合刷新令牌轮换和用于企业 SSO 的 OAuth/OIDC。每个权限检查都集中管理 — 绝不分散在各个路由处理程序中。

您的 CI/CD 管道包含什么?

GitHub Actions 工作流在每个拉取请求上运行类型检查、单元测试、集成测试和代码检查。预览部署在 Vercel 上自动启动。生产部署实现零停机时间,失败时自动回滚。我们还包括依赖扫描、AWS 服务的 Docker 镜像构建和数据库迁移门控。

发布后您提供持续支持吗?

每个合作项目都包括 30 天的上线后支持,涵盖错误修复、性能监控和部署协助。之后,我们提供月度保留套餐,用于持续开发、基础设施管理和随时待命支持。我们会详细记录所有内容,以便您的内部团队可以在没有我们的情况下维护系统。

您如何确保后端能够处理高流量?

我们从一开始就设计水平可扩展性 — 无状态 API 路由、连接池、Redis 缓存和边缘部署。在发布前,我们运行负载测试,模拟您预期流量的 10 倍。每个端点都配有延迟追踪工具,当 P95 性能下降时会触发警报,这样您就能在用户发现问题之前抓住它。
