I will build a custom CRM web app for your business


About this gig
bMost CRM problems are not a data problem. They are a workflow problem. You already know who your leads are. What you are missing is a system that tracks them, follows up, and shows you the numbers that actually decide whether you get paid.
I build custom CRMs end to end, alone. I shipped a full production CRM solo in weeks and I run a live multi-tenant SaaS with a paying client right now. That means I do not hand you code and disappear. I architect the data model, build the frontend and backend, wire the integrations, and make sure it works in the real world.
Stack: React, TypeScript, Node, and Supabase or Firebase for auth and database. Stripe if you need billing. Clean, documented code you own outright.
I have a finance and analytics background (dual master's), so I build the dashboard around the metrics that move money, not vanity charts. Pipeline stages, follow-up tracking, conversion, revenue per client.
Tell me what your sales process looks like today and where deals fall through. I will map it into a working system. What does your current pipeline run on?
