Need a SaaS MVP built properly from day one?
I build production-ready SaaS applications, SaaS MVPs, internal tools, and AI-powered features for startups and businesses that need reliable software they can actually ship and scale.
My core stack is Next.js, React, TypeScript, Node.js, Supabase, PostgreSQL, and FastAPI.
You get clean architecture, tested code, solid database design, and a product that is built for real users — not a prototype that needs to be rewritten six months later.
🟠 WHAT I BUILD
→ SaaS MVPs & SaaS applications
From database architecture and authentication to dashboards, billing, APIs, and deployment.
→ B2B SaaS & internal tools
Admin dashboards, RBAC, CRUD systems, workflows, reporting, and operational platforms.
→ AI-powered SaaS features
AI agents, chatbots, RAG, tool calling, lead qualification, and API integrations using OpenAI and Claude.
→ Full-stack web applications
Next.js, React, TypeScript, FastAPI, Node.js, Supabase, PostgreSQL, REST APIs, and real-time features.
→ Payments & third-party integrations
Stripe, WhatsApp, webhooks, REST APIs, and custom integrations.
🟠 RECENT PROJECTS
→ SaaS admin platform for a travel agency
12 modules, RBAC, a 9-step trip builder, rich text editing, and advanced tables.
React + TypeScript + Supabase.
Built and deployed in 30 days.
→ Omnichannel AI sales chatbot
WhatsApp, Facebook, Instagram, and web.
5-stage lead qualification, automated lead capture, LangChain, LangGraph, FastAPI, Redis, and Supabase.
→ Internal quoting & proposal platform
Multi-role RBAC, immutable quote versioning, PostgreSQL Row-Level Security, and 71 passing tests.
Built for production and deployed on Vercel.
→ AI MVP scoping tool
Founders describe their idea and Claude turns it into a structured, buildable product specification.
Next.js + Supabase + Claude API.
🟠 RESULTS
⭐ “Exceeded expectations in many regards.”
⭐ Reworked a client's application and reduced load time from 13 seconds to 1.3 seconds.
The projects in my portfolio aren't toy demos.
They're deployed applications built for real clients and real users.
🟠 HOW I WORK
→ I scope before I build.
→ I keep architecture simple, maintainable, and documented.
→ I test critical functionality before delivery.
→ I communicate clearly and keep timelines realistic.
→ I don't disappear after launch.
My goal is simple:
Build the right product, ship it, and leave you with code another developer can actually work with.

Ehtisham F.
has worked

You don't hire a Next.js developer to write code. You hire one to make sure your product actually ships, works under pressure, and does not fall apart six months later.
Because when it does not ship on time, you lose revenue. When it breaks in production, you lose users. When the codebase is a mess, no developer wants to touch it, and you end up paying for it for months.
That is the problem I solve.
Over the past few years, I have delivered full-stack Next.js and React projects across multiple industries. A live US-based AI SaaS platform where I shipped 86+ production features, including AI assistant wizards, AWS Bedrock knowledge bases, multi-tenant vendor portals, real-time voice systems, and full billing engines. A financial analytics platform built with Next.js and Supabase with an AI-powered chat feature, giving users instant data insights. A full social platform on Next.js 13 with Better authentication and PostgreSQL with Prisma. A property dashboard with complex data visualisations and third-party API integrations. And more in between.
These are not side projects or client demos. These are production systems handling real users, real data, and real business logic every single day.
On Upwork: 100% Job Success Score. Top Rated. 25 completed jobs. 2,443+ hours logged. $20K+ earned. On GitHub: 2,125 contributions in the last year. I am not someone who codes when clients are watching. I code every day. Every client review says the same thing. Clear communication, delivered on time, with quality that went beyond what was promised.
What I Build:
• Next.js and React Development: Building fast, scalable, production-ready applications using the latest Next.js features, including app router, server components, SSR, and SSG. Whether you need a high-performance SaaS product or a complex data-heavy dashboard, I make sure every page loads fast, every component is clean, and your users get a smooth experience from day one.
• SaaS and Multi-Tenant Platforms: Designing and shipping complete SaaS products with multi-tenant architecture, admin panels, role-based access control, real-time data, and billing systems built to scale. I have taken products from architecture decisions on day one, all the way to live deployment, so you are not patching problems together six months later.
• AI and LLM Integration: Adding real AI value where it makes sense using OpenAI, Anthropic, Google Gemini, AWS Bedrock, and voice agent systems. I have built AI assistant wizards that cut onboarding from hours to minutes, knowledge bases that give AI agents real business context, and voice systems that handle live customer interactions. I do not add AI for its own sake. I add it where it genuinely makes your product smarter.
• Backend and API Architecture: Building secure, well-structured backends using Node.js, tRPC, PostgreSQL, Prisma, Supabase, and REST APIs. Clean database design, background jobs, webhooks, and third-party integrations handled properly so your system holds up when real traffic hits.
• Full Project Delivery: Taking your project from initial planning through to deployment and handoff with clean, documented code. No disappearing after launch. You get a developer who is accountable from the first conversation to the final commit.

Senior Frontend Engineer with 10+ years architecting large-scale, high-load applications — now focused on building production-grade UIs for AI products, engineering agentic coding pipelines, and pioneering Generative UI frameworks.
Currently founding UI developer at Tesari.ai, building interfaces for an AI-driven intelligence platform where auditability and real-time depth are non-negotiable.
I help teams ship LLM-powered interfaces, architect autonomous developer-agent ecosystems, and adopt AI-assisted development workflows (Claude Code, agentic tooling) without sacrificing architecture, performance, or quality.
AI ENGINEERING, AGENTIC DEVELOPMENT & GENERATIVE UI
• Building production UIs for AI/LLM products: chat & agent interfaces, streaming responses, tool-calling visualizations, human-in-the-loop review flows.
• Generative UI Architecture: Designing and implementing systems for real-time, dynamic interface generation, transforming structured LLM outputs into context-aware UI components on the fly.
• Agentic Coding Pipelines & Infrastructure: Engineering autonomous developer-agent environments using Claude Code; setting up project contexts, custom agent skills, and multi-agent execution workflows.
• Automated Quality & Security Guardrails: Developing specialized monitoring agents dedicated to autonomous code review, continuous technical debt tracking, and security vulnerability detection.
• Advanced Workflow Automation: Designing custom agentic orchestrations to automate complex refactoring, end-to-end test generation, and multi-step repository-wide development tasks.
• Integrating LLM APIs (Anthropic, OpenAI): Embedding advanced capabilities into apps via high-performance streaming, structured outputs, function/tool calling, and RAG-driven UIs.
• Designing UX for AI Trust: Architecting interfaces focused on source provenance, citations, deep auditability, and explainable AI outputs.
• Enterprise-Grade Workflows: Establishing AI-assisted workflows that scale without sacrificing core codebase quality, performance, and maintainability.
