Abdul R.

I help SaaS founders and startups build, launch, and scale production-ready SaaS and AI web applications using Next.js, React, TypeScript, Supabase, PostgreSQL, Node.js, and modern AI/LLM integrations. With 4+ years of Full-Stack Development experience, I work across complete SaaS products, from database design, authentication, APIs, dashboards, and billing to AI features, third-party integrations, deployment, monitoring, and ongoing production improvements. My core expertise includes SaaS Development, AI Development, Web Application Development, API Integration, Supabase, React, Next.js, Claude, OpenAI API, PostgreSQL, and TypeScript. WHAT I CAN BUILD & IMPROVE • SaaS MVPs and production SaaS applications • AI-powered web applications and SaaS platforms • Next.js, React, TypeScript, and Tailwind CSS frontends • Supabase authentication, PostgreSQL databases, and Row Level Security • REST API development and third-party API integrations • OpenAI API, Claude, LLM integrations, and AI Agent Development • AI workflows, structured outputs, document processing, and automation • SaaS dashboards, admin panels, portals, and user workflows • Stripe subscriptions, payments, billing, credits, and webhooks • Existing SaaS codebase audits, debugging, refactoring, and feature development • Production deployment, performance optimization, monitoring, and scaling RELEVANT SAAS & AI PROJECTS Relevant projects include myTpen, where I lead development across 9 connected SaaS applications with shared authentication, data, AI/OCR workflows, APIs, and automation; TaxNoticePilot, a live AI SaaS with paying customers built with Next.js, PostgreSQL, Stripe, authentication, monitoring, and SOC 2 Type II controls; Docr, an AI/OCR SaaS with document processing, structured outputs, a public API, and credit-based usage; IENA, a NestJS/PostgreSQL recommendation engine handling 100,000+ applicants across 1,500+ camps; and DeepNApp, where I rescued an AI-generated React codebase, rebuilt unstable features and database architecture, and restructured it into a maintainable monorepo.

I focus on reliable SaaS Development, maintainable React/Next.js architecture, secure Supabase/PostgreSQL implementations, dependable API integrations, and practical AI features built around real product workflows. Whether you need a SaaS MVP, AI-powered web application, Supabase development, React/Next.js feature development, Claude/OpenAI integration, API Integration, or help stabilizing an existing product, send me the project details and I’ll identify the most practical path to production.
