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.

專案失敗的原因

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.

合規

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.

我們構建的內容

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.

我們的流程

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.

常見問題

您在後端開發中使用哪些語言和框架?

我們主要使用Node.js和TypeScript — Next.js API routes、tRPC和Express。對於資料庫，我們使用PostgreSQL(透過Supabase或AWS RDS)搭配Drizzle ORM。我們為工作選擇適當的工具，但不會在六種語言之間頻繁切換。深入掌握一個技術棧勝過淺嚐許多語言。

您可以與我們現有的後端程式碼庫合作嗎?

可以。大多數專案都以現有系統的架構審計開始。我們識別技術債、效能瓶頸和安全漏洞，然後提出有針對性的修復方案。當重構足以解決問題時，我們不會進行重寫。如果重寫確實必要，我們會向您展示支持這一決定的數據。

您如何為多租戶SaaS處理身份驗證和授權?

我們在PostgreSQL中實現行級安全性，結合在API和資料庫層強制執行的RBAC策略。驗證流程使用Supabase Auth或自訂JWT搭配刷新令牌輪換和企業SSO的OAuth/OIDC。每個權限檢查都是集中管理的 — 永遠不會分散在個別路由處理程序中。

您的CI/CD管線包括什麼?

GitHub Actions工作流程在每個pull request上執行型別檢查、單元測試、整合測試和linting。預覽部署在Vercel上自動啟動。生產部署實現零停機時間，失敗時自動回滾。我們還包括依賴掃描、AWS服務的Docker映像建置和資料庫遷移閘門。

您在上線後提供持續支援嗎?

每個專案都包括30天的上線後支援，涵蓋錯誤修復、效能監控和部署協助。之後，我們提供月度保留套餐，用於持續開發、基礎設施管理和隨時待命支援。我們記錄所有內容，讓您的內部團隊可以在沒有我們的情況下維護系統。

您如何確保後端能夠處理高流量?

我們從一開始就設計水平可擴展性 — 無狀態API路由、連接池、Redis快取和邊緣部署。上線前，我們運行模擬10倍預計流量的負載測試。每個端點都配備延遲追蹤工具，警報會在P95效能下降時觸發，讓您在用戶察覺問題前就發現它。
