Project details

I've built backend systems handling 60K+ active users and €1.5M in monthly transactions (whydonate.com). I'll build yours to the same standard.

You get production-ready APIs, optimized database schemas, and cloud deployment, not tutorial-grade boilerplate. Includes error handling, auth, rate limiting, and monitoring from day one.

Stack: FastAPI or Node.js + PostgreSQL/MySQL/NoSQL + AWS Lambda or Cloudflare Workers.

Starter: $1000 | 7 days "API & DB Foundation"
→ Up to 5 REST endpoints + schema design + migrations + JWT/OAuth auth + source code + docs

Standard: $1,800 | 15 days "Production-Ready"
→ Up to 15 endpoints (REST/GraphQL) + DB optimization + CI/CD + AWS/Cloudflare deploy + rate limiting + logging + API docs + architecture diagram + 1 revision

Advanced: $3,500 | 30 days "Scalable Infrastructure"
→ Unlimited endpoints + microservice/serverless arch + DB sharding + full AWS infra (Lambda, RDS, S3, CloudFront, Secrets Manager) + load testing + monitoring + full docs + 2 revisions

Bengaluru, India - 1:36 am local time
Top Rated Senior Backend Developer building production APIs, SaaS backends, databases, and cloud infrastructure with Node.js, Python/FastAPI, PostgreSQL, AWS, Cloudflare, Redis, Docker, REST, GraphQL, WebSockets, and AI integrations.

I help startups, SaaS companies, agencies, and product teams build, fix, and scale backend systems that are stable in production.

Core backend work I handle:

- SaaS backend architecture for MVPs, dashboards, marketplaces, internal tools, and B2B platforms
- REST API and GraphQL API development
- Node.js, Express.js, NestJS, Python, FastAPI, and serverless backend development
- PostgreSQL, MySQL, Redis, Supabase, schema design, indexing, migrations, and query optimization
- AWS Lambda, API Gateway, S3, CloudFront, RDS, CloudWatch, and deployment automation
- Cloudflare Workers, DNS, SSL, custom domains, R2, KV, D1, and edge infrastructure
- Authentication, authorization, JWT, OAuth, RBAC, and secure API permissions
- Stripe, subscriptions, ledgers, webhooks, and idempotency-safe payment workflows
- AI integrations, OpenAI/Anthropic APIs, RAG pipelines, chatbots, and backend automation
- Microservices, queues, caching, monitoring, CI/CD, Docker, and production troubleshooting

Recent production results:

- Scaled backend systems handling 2M+ daily API requests
- Processed EUR 1.5M+ monthly transactions across payment providers
- Reduced API latency by 70% through backend, database, and infrastructure optimization
- Built custom-domain and SSL automation for 1K+ domains

Clients hire me when they need a backend engineer who can own the problem end to end: understand the business requirement, design the architecture, write clean code, deploy safely, and communicate clearly.

Tech stack:
Node.js, TypeScript, Python, FastAPI, Express.js, NestJS, PostgreSQL, MySQL, Redis, Supabase, AWS, Cloudflare Workers, Docker, GitHub Actions, REST APIs, GraphQL, WebSockets, Stripe, OpenAI, LangChain, RAG, microservices, serverless architecture.

Send me your current stack and the backend problem you want solved.
