I build AI SaaS products that are live and earning. Kalam serves 10,000+ weekly active users. KAGU processes 1,000+ orders a day. Blackstone LOMS has passed 100 sales. These are a few of 90+ shipped projects, and I build and scale them as a partner, not a hired hand. Most freelancers show you a stack list. I show you products with users. I help founders and product teams build SaaS products that actually ship, not prototypes that stall in development. Most web projects don't fail because of bad developers. They fail because of early technical decisions, wrong architecture, a bloated stack, unclear scope, that create a mess that's expensive to fix later. I get involved early so that doesn't happen. Whether you're launching a brand-new product or scaling an existing one, I take ownership of the technical side so you can focus on the business. My focus is full-stack web products: React and Next.js on the front; Node.js, Laravel, or Python on the back; PostgreSQL where it matters. I've built two-sided marketplaces, subscription products, AI-integrated platforms, and backend-heavy web apps, from greenfield MVP to production scale. What I typically work on: SaaS product development (MVP to production) Backend APIs, system architecture, and database design Performance optimization and scaling AI/LLM feature integration into existing products Long-term, ongoing product development I don't take on projects I can't deliver properly. If the scope is unclear, I'll tell you before we start, not halfway through. Top Rated Plus · 89 jobs · 100% job success · 8+ years
