Maaz A.

I'm here to build and ship features for your SaaS product, including the AI features your users keep asking for. Adding an LLM assistant that works with your real data, or fixing a codebase that slows down every release, either way, I'll get it into production and keep it running as you grow. Six years as a Full Stack Web Developer in React, Next.js, and Node.js. Because I've shipped production code for years, the AI work doesn't stop at a demo that only works on the happy path: RAG that answers from your own documents, agents that call your APIs, error handling for the times the model returns something it shouldn't. I've also built SaaS platforms from zero, rescued stalled codebases, and shipped OpenAI, Anthropic Claude, Stripe, Shopify, Amazon SP-API and MUX integrations into production. 42 contracts from 15 clients. Two out of three jobs on my profile come from someone who hired me before. WHAT I BUILD * AI Features for SaaS - LLM integration with OpenAI and Anthropic Claude APIs, RAG over your documents and data, AI agents with tool calling, chat and assistant features inside your product. * Full-Stack SaaS Development - React, Next.js, Node.js (Express, NestJS). Python (FastAPI, Django), PostgreSQL, MySQL. MVPs from zero, new features on existing products, or rescuing codebases someone else left half-finished. * API & Systems Integration - Stripe, Shopify, Amazon SP-API, MUX, HubSpot. REST, GraphQL, webhooks, payment gateways, third-party APIs that are badly documented and still have to work. * Cloud & DevOps - AWS, Docker, DigitalOcean. * Workflow Automation - n8n, Make, Zapier for the back-office processes around your product. Why clients choose me: - Bug warranty - 30 days after delivery, any defect in code I wrote gets fixed at no cost. - Weekly written progress updates, so you always know where the project stands. - Code documented well enough that the next developer you hire can pick it up without me. - Post-deployment support and performance tuning - I don't disappear at launch. Message me with the feature on your roadmap or the part of your codebase that keeps breaking, and I'll map the shortest path to shipping it. Already have a spec? Send it over and I'll build to it. Either way you'll get a plan with timeline and cost before you commit to anything.
