HELPING FOUNDERS BUILD MVPs OR SCALE THEIR EXISTING APPs | 3x FASTER 50% LOWER COST Hi, I am Mohsin building MVPs that are production-ready, and ship them faster than traditional dev cycles. As a Lovable.dev, Replit Base44 Top-Rated Freelancer on Upwork with 100% Job Success, I help founders go from AI-driven prototypes to revenue-ready apps with Lovable + Supabase, Replit, Bolt Base44 or Cursor. I specialize in: - 0 to 1 launches, having built scalable backend systems for SaaS and consumer web applications. - Expert in AI integration and modern development with Lovable, Replit, Bolt and Cursor - Proven track record launching MVPs that scale from startup to enterprise - End-to-end project ownership with transparent communication WHAT I BUILD: - MVP development and SaaS development: idea to working MVP to live product taking payments - AI app development and AI agent development: Claude API, OpenAI API, RAG, LLM integration, chatbots, OpenClaw agents - Lovable rescue and vibe coding cleanup: Lovable, Base44, Bolt.new, Replit and v0 apps that are 80% there but broken or not production-ready - Migrations: Lovable to Claude Code, Bolt.new to Claude Code, Replit to production, Base44 to production, no-code to production - Supabase architecture: auth, Row Level Security (RLS), edge functions, Postgres schema design - Stripe integration, webhooks and subscription billing - Automation workflows with n8n, Zapier and Make - Landing pages with technical SEO, GA4 and GTM tracking - Claude Code and CLAUDE.md setup so your team builds AI-native THE GUARANTEE: - Free scoping call before you spend a penny. We map the features, flows and milestones. - If we're not a fit, you walk away with a clearer vision anyway. - Working prototype in 3 weeks. Real functionality, live database, not a mockup. - Unlimited revisions within scope, with detailed specs agreed upfront. HOW WE CAN WORK: 1. Fixed-price build: MVP, SaaS platform, migration or rescue, scoped upfront with a proposal within 24 hours 2. Fractional developer (10 to 30 hrs/week): ongoing feature development inside your product 3. Post-launch retainer (from $650/month): priority fixes, updates, monitoring and improvements so your product never goes stale. Most clients start with a fixed build and keep the retainer. You own the code either way. Zero lock-in. TECH STACKS: Frontend: React.js, Next.js, Angular, Vue.js, Tailwind CSS
