I will develop a custom web app or internal tool for your company
Tiago Lemos
About this gig
Need a custom web app built right the first time? I build production-grade web apps and SaaS MVPs with Next.js, Supabase, and TypeScript for founders, operations teams, and agencies who need real software, not another no-code shortcut.
What I build:
. Internal business tools and dashboards
. Client-facing SaaS products (with auth, billing, multi-tenant)
. Custom proposal builders, scheduling systems, CRMs, field ops tools
. API integrations with ERPs, Gmail, Slack, Stripe, OpenAI etc
How we work (you never pay until you're confident):
1. Discovery: we map your workflow and find the highest-impact build
2. Demo: I build a working preview so you see it before committing
3. Proposal: full spec and pricing, then you decide
Why me:
. Real portfolio of live interactive demos, not just screenshots
. Every project deployed, documented, and handed off with source code
. Direct communication, no account managers, no offshore handoffs
Let's turn your idea into software. Send me a message with what you want to build and I'll reply within a few hours.

FAQ
Will I own the source code?
Yes, 100%. Source code is handed over to you (GitHub repo transfer or zip) on project delivery. No licensing, no vendor lock-in, no strings.
How does the "you don't pay until you're confident" process work?
The discovery call is free. I then build a working demo of your project so you can see the solution before committing. You only pay once you've seen the demo and approved the final proposal.
Do you provide support after delivery?
Yes. Every project includes 14 days of free bug-fix support after launch. For ongoing feature work, I offer a monthly retainer or hourly blocks.
Can you work with non-technical founders?
Yes, most of my clients are non-technical. I handle all the tech decisions (stack, hosting, architecture) and translate everything into plain language so you always know what's happening.
Who hosts the app after delivery?
You do. I deploy to Vercel (frontend) and Supabase (database) under your own accounts so you're never locked to me. Both have generous free tiers that cover most early-stage projects at zero cost.
Can you build on top of my existing codebase?
Depends on the stack. If it's Next.js, React, or Node, yes. For other stacks I can integrate with the API but won't modify the core code. Share your repo in the discovery call and I'll tell you straight up.
What integrations can you build?
Anything with a public API. Most commonly: Gmail, Slack, Stripe, OpenAI, Google Workspace, custom ERPs, and CRMs via REST or webhooks. If the tool has docs, I can integrate it.
