I will build a fast, scalable full stack saas application


About this gig
Got a SaaS idea, dashboard, or data-heavy app that needs actually to perform? I build full-stack web apps that scale. Clean architecture, fast load times, and UIs that don't fall apart under real usage.
I've shipped apps that render 100k+ data points in real time, built 3D spatial tools, and led engineering on a production SaaS product used across Canada. You're not getting a template. You're getting an engineer who's solved hard problems before.
What I build:
- SaaS platforms and MVPs ready for investors
- Admin dashboards and data visualizations
- REST and GraphQL APIs
- Spatial and map tools
Stack:
Frontend: React, Svelte, Next.js, WebGL, Mapbox
Backend: Node.js, Rust, Python, Express
Database: PostgreSQL, MongoDB, Supabase, Firebase
DevOps: GCP, AWS, Docker, CI/CD
Every project comes with clean, modular code and architecture that scales. You work directly with me, no middlemen and no offshore handoffs.
Still figuring out exactly what you need? Message me before you order. I'll tell you straight whether I'm the right fit and what your build should actually 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.
