Rising Talent
Project details
You have a SaaS idea — I'll turn it into a live, working product.
I'm a Full-Stack SaaS Engineer with 6+ years of experience shipping production-grade web applications. I specialize in the MERN stack (MongoDB, Express, React, Node.js) and Ruby on Rails, and I've built SaaS platforms ranging from simple landing-page + dashboard combos to complex multi-tenant systems with API integrations and AI-powered features.
What I build:
B2B and B2C SaaS platforms
Multi-tenant applications with role-based access control
Subscription & billing systems (Stripe, PayPal)
Internal tools and admin dashboards
REST & GraphQL APIs
Real-time features (WebSockets, live notifications)
My tech stack:
Frontend: React, Next.js, TypeScript, TailwindCSS
Backend: Node.js, Express, Ruby on Rails, Python (FastAPI)
Database: PostgreSQL, MySQL, MongoDB, Redis
Cloud: AWS (EC2, S3, RDS, Lambda), Heroku, Render, Vercel
DevOps: Docker, GitHub Actions, CI/CD
I don't just write code — I ask the right questions upfront, understand your business goals, and build something you can grow on.

I specialize in three areas that directly impact your bottom line:
→ Building and scaling SaaS platforms
→ Integrating production AI features, RAG, fine-tuning, AI agents, LangChain not toy demos
→ Modernizing legacy systems into fast, cost-efficient architectures that stop hemorrhaging AWS bills
Whether you're a startup shipping v1 or an enterprise untangling a decade-old monolith, I've done both and I've led teams of 15+ engineers doing it.
Numbers, not promises:
→ Cut AWS costs by 40% through a zero-downtime, route-by-route platform migration for a major EdTech product
→ Slashed page loads from 15 seconds to under 2 seconds by rebuilding the data access layer
→ Architected a ticket inventory system handling 1M+ monthly users with zero overselling during flash sales
→ Built RAG-powered AI engines used by thousands of active users in production
→ Launched 5+ SaaS products independently from first schema to production deployment
What I can help with
AI SaaS product development.
Workflow automation using n8n and Make com
Custom API integrations.
CRM, sales, and marketing automation.
AI agents and business logic workflows.
Dashboards, analytics, and reporting systems.
Multi-step automation for operations and support.
