Project details

I build serverless backends on Cloudflare Workers + Supabase that run at the edge with <50ms latency globally. Proven on whydonate.com (60K+ users, €1.5M/mo transactions) and multiple Cloudflare projects rated 5.0 by clients.

You get Workers, KV, D1, R2, Supabase Auth & DB deployed, tested, and production-ready. Not a boilerplate starter kit.

Starter: $500 | 4 days "Worker + KV Setup"
→ Single Worker + KV storage + 3–5 API routes + CORS + error handling + caching + docs

Standard: $1,500 | 10 days "Full-Stack Serverless"
→ Multi-Worker setup + D1/KV + Supabase Auth + real-time CRUD + edge caching + webhook processing + CI/CD + 1 revision

Advanced: $4,000 | 30 days "Enterprise Architecture"
→ Multi-tenant Workers + D1, KV, R2, Supabase (Auth, DB, Storage, Edge Functions) + advanced caching + monitoring + alerting + full CI/CD pipeline + architecture docs + 2 revisions

Every tier includes source code, documentation, and deployment to your Cloudflare account.

Bengaluru, India - 4:57 am local time
I build and scale production backend systems, AI-powered applications, and cloud infrastructure for SaaS products handling real users, real payments, and high-volume workloads.

My core stack is Node.js, TypeScript, Python, PostgreSQL, AWS, Cloudflare, Redis, and LLM APIs. I work across backend architecture, AI integrations, APIs, databases, infrastructure, payments, and production reliability.

At WhyDonate, I work on systems serving 4M+ API requests per day and supporting €1.5M+ in monthly payment volume. My work has included reducing API latency by ~70%, building event-driven data pipelines, payment and payout systems, queue-based processing, Elasticsearch synchronization, and improving CI/CD from roughly 6 minutes to around 1 minute.

I also work with AI and LLM-based systems, including:

* LLM API integration and production AI features
* RAG pipelines and retrieval architecture
* AI-generated code and response evaluation
* Prompt and response quality analysis
* Structured output and JSON validation
* Evaluation of technical correctness, edge cases, and hallucinations
* AI gateways, inference routing, and observability

What I can help you with

* Backend architecture for SaaS and AI products
* Node.js / TypeScript / NestJS APIs
* Python / FastAPI backend development
* AI and LLM integrations
* RAG systems and vector/retrieval workflows
* AI coding evaluation and technical response review
* PostgreSQL, MySQL, Redis, Elasticsearch
* AWS architecture and deployment
* Cloudflare Workers and edge systems
* Stripe and payment infrastructure
* Performance optimization and scalability
* Queues, background jobs, and event-driven systems
* CI/CD, Docker, Nginx, PM2, and production deployments
* Debugging and stabilizing existing production systems

I’ve worked on fintech, fundraising, marketplaces, logistics, real estate platforms, and AI-enabled SaaS products.

I’m most useful when a project needs someone who can go beyond implementing tickets: understand the architecture, identify what is actually causing the problem, and ship a solution that will hold up in production.

If you need a backend or AI engineer who can take ownership of a system from architecture through deployment, feel free to reach out.
