Most developers build what you ask for. I build what your business actually needs. With a 98% Job Success Score, Top Rated Plus status, and 23 completed projects across 3,200+ hours of real delivery, I've spent 6 years helping startups and product teams ship SaaS platforms, AI-powered applications, and scalable web systems that hold up under real-world load. My core stack is React, Next.js, Node.js, and MongoDB; but the last couple of years, most of what I build sits at the intersection of full-stack engineering and AI. GPT-powered workflows, intelligent document processing, LangChain integrations, chat systems, automation pipelines. Features that used to require a dedicated ML team now ship in weeks when the architecture is right. One thing I do differently: I use AI-assisted development tools like Cursor, Claude, and GitHub Copilot as part of my actual workflow; not as a talking point. This means faster iteration cycles, cleaner code on first pass, and fewer back-and-forth revision rounds for you. A few things from recent projects: - Built a FinTech lending platform handling multi-step loan origination, KYC verification, and payment processing; serving thousands of active borrowers with zero downtime across 18 months. - Developed a telemedicine platform with real-time video consultation, EHR integration, and HIPAA-aligned data handling; onboarding 2,500+ patients in the first quarter post-launch. - Shipped a SaaS LMS for an EdTech company with course builder, assessment engine, progress tracking, and Stripe subscription billing; from MVP to 4,000+ enrolled users in 8 months. - Built an AI-powered document processing system using OpenAI and LangChain that reduced manual review time by 70%, processing 10,000+ documents per month automatically. - Delivered a marketplace platform with multi-vendor support, role-based dashboards, advanced search, and integrated payments; scaled to 8,000+ active users within 6 months of launch. What I typically work on: - Full-stack SaaS platforms; auth, subscriptions, multi-tenancy, role-based access, API integrations, the full product. - AI features and integrations; OpenAI APIs, LangChain, chat systems, document processing, workflow automation that replaces real manual work. - Scalable backend systems; clean modular architecture, PostgreSQL and MongoDB, AWS and Docker, CI/CD pipelines, and code that doesn't fall apart when traffic doubles. - Cross-functional product work; I've worked across FinTech, HealthTech, EdTech, and marketplace products. I understand the compliance requirements, the UX constraints, and the business logic specific to each. Why clients come back: - 98% Job Success Score across 23 projects isn't luck. It comes from taking full ownership of the outcome; not just the code. I flag problems before they become expensive, write architecture that the next developer can read, and stay accountable long after the final delivery. If you're building a SaaS product or AI-powered application and want someone who takes the whole thing seriously; send me a message. I'll come back within a few hours with a straight assessment of what it would take to build it right.
