I will build a fast, scalable full stack saas application


About this gig
Does your dashboard freeze at 5,000 rows? I've built interfaces that render 100,000+ data points in real time, and I can do the same for your product.
I'm a full-stack engineer who led development of a production SaaS platform used across Canada, and I've built 3D and map-based spatial tools. I take on projects where speed, clarity, and scale matter.
What I build
- Admin dashboards and data visualizations that stay fast with real data
- MVPs for SaaS products, built cleanly enough to show investors and extend later
- Map and spatial tools (Mapbox, WebGL, 3D)
- REST and GraphQL APIs behind them
What you get
- Clean, modular, documented code you own
- A deployed, working build, not just a repo
- Direct communication with the engineer doing the work
- Fast load times and a UI that holds up under real usage
Stack:
· React, Next.js, Svelte, WebGL, Mapbox
· Node.js, Rust, Python · PostgreSQL, MongoDB, Supabase
· GCP, AWS, Docker, CI/CD
Not sure what you need? Message me before ordering. Send a short description of the project, your data size, and your deadline, and I'll tell you honestly whether I'm the right fit and what it should cost.

FAQ
Will I own the source code and Intellectual Property?
Yes, 100%. Upon delivery and payment, you hold full rights to the code, design, and intellectual property. I do not retain any rights to your product.
Can you work on my existing app/codebase?
Yes, but please message me first. I typically require a code audit (via the Basic Package) to assess the architecture and code quality before committing to new feature development.
Do you offer support after the project is finished?
Yes. I provide a 7-day warranty period for bug fixes on my code. For ongoing maintenance or feature updates, we can discuss a monthly retainer or a new milestone.
