Minor updates to Ruby on Rails site! (add a product category)
Hamza is fantastic! Knowledgeable, professional and most importantly: honest. You'll be hard-pressed to find a better freelancer for your needs. I look forward to working with him again in the near future.

About Hamza
AI SaaS & Full-Stack Product Engineer | React, Next.js, Node.js, Rails
Lahore, Pakistan - 10:56 am local time
I help founders and product teams build, fix, and scale AI-powered SaaS platforms using React, Next.js, Node.js, Ruby on Rails, PostgreSQL, Supabase, Stripe, OpenAI, Claude, and cloud infrastructure.
The projects I’m best suited for are usually already serious: an MVP is built but unstable, the dashboard is half-working, APIs are unreliable, payments need cleanup, AI workflows are breaking, or the architecture needs review before launch.
I also build MVPs from scratch, but with the right structure from day one so they don’t need to be rebuilt later.
🚀 Recent work includes:
Worked on Tenna, a production platform with real users, improving system stability, APIs, and workflows
Built CoBroker AI, an AI-driven platform with structured workflows and reliable LLM outputs
Improved backend-heavy systems like IntelMS with authentication, role-based access, and system reliability
💡 What I help with:
SaaS MVP development and production launch
Existing codebase takeover, debugging, and stabilization
React / Next.js dashboards, admin panels, and user workflows
Node.js / Rails backend APIs, authentication, roles, and database logic
OpenAI / Claude / LLM integrations, AI workflows, automation, and RAG features
Stripe, Stripe Connect, subscriptions, billing, webhooks, and payment flows
PostgreSQL / Supabase schema design, performance, and data structure
AWS / Vercel / Docker / CI/CD deployment and production hardening
🧠 Skill set:
Primary stack: React, Next.js, Node.js, Ruby on Rails, TypeScript, JavaScript, PostgreSQL, Supabase, MongoDB, MySQL, Tailwind CSS, React Native
AI stack: OpenAI API, Anthropic Claude, Claude Code, Cursor, Copilot, RAG, embeddings, AI agents, LLM workflows, automation
SaaS/product stack: SaaS architecture, MVP development, admin dashboards, multi-tenant systems, role-based access, authentication, billing, subscriptions, Stripe, Stripe Connect, API integrations, webhooks
Production stack: AWS, DigitalOcean, Vercel, Docker, CI/CD, Redis, WebSocket, SSE, performance optimization, security hardening, testing, debugging, deployment
✅ How I work:
Understand the existing system before making changes
Identify weak points before adding more complexity
Deliver in small, stable iterations
Keep communication clear and predictable
Focus on long-term maintainability, not quick fixes
Take ownership from architecture to deployment
I’m not only useful when everything is perfectly documented. I’m comfortable reading existing code, understanding business logic, asking the right questions, and turning unclear requirements into working product improvements.
If your platform is close to launch, already live, or starting to break under real usage, I can help you turn it into a stable, scalable product.
💬 Send me your goal, current app/codebase situation, timeline, and budget range, I’ll reply with a clear plan and practical next steps.
