Custom app development
Custom app development for founders and businesses.
Web applications, SaaS platforms and internal tools, designed around your process and built for daily use.
I’m Nareg, a senior full-stack developer with almost 10 years of experience building for the web. I scope, design and build custom web applications, and stay your point of contact from the first call to launch.
What you get
A custom web application, ready for real users.
Scope before code
We agree on what the first release must do, what can wait and how we will know it works. You know what is being built before the build starts.
Design and engineering in one place
Screens are designed in Figma and built in TypeScript, with Next.js or SvelteKit on the front end and PostgreSQL through Supabase behind it.
- TypeScript
- Next.js
- Svelte.js
- Supabase
- Postgres DB
Accounts, roles and private data
Logins and permissions are enforced in the database with Postgres row-level security, so each user sees only the data they are allowed to see.
Dashboards, reports and exports
Analytics dashboards, PDF and email reports and data-export APIs, for the people who run the business as well as the people who use the app.
Tested, monitored and deployed
Automated tests with Vitest and Playwright, deploys through GitHub Actions, and error monitoring with Sentry once the app is live.
How it works
From first call to a product in daily use.
Brief
Send a short message about the problem or the idea. I reply directly, and we schedule a call if there is a fit.
Scope
We define the first release: who uses it, the main workflows, the data it holds, and what can wait.
Build
Design and engineering with regular updates, and working versions to review along the way.
Launch
The app goes to production with monitoring in place. From there we decide together what comes next.
Proof
Custom applications in production.
Classroom coaching platform for Texas school districts
Core engineer on a ground-up rewrite to Next.js 16, React 19 and Supabase: a redesigned schema with row-level security, a versioned scoring engine, 10+ analytics dashboards, PDF and email reports and a district data-export API. It now serves 6 districts, 100+ schools and 3,000+ teachers.
JustiConnect
A legal tech platform I co-founded and designed, built and launched end to end in SvelteKit: lawyer matching, scheduling and client management in one product. 100+ lawyers onboarded in the first year.
HotNewHipHop.com
Led the rewrite of a high-traffic online magazine from PHP to Next.js, for 30M+ monthly visitors, with scalable APIs and back ends built for that traffic.
Client reviews

FAQ
Common questions about custom apps.
I’m not technical. Can I still work with you?
Yes. Most of my work is directly with founders and business owners. I explain technical decisions in plain language, keep you updated as the work moves along, and remain the main point of contact.
Do you build mobile apps?
I build web applications. They run in the browser on phones, tablets and desktops, so one product serves every device without separate app store releases.
Can you take over or rebuild an existing app?
Yes. I was a core engineer on the rewrite of a platform now used by 3,000+ teachers, moved from a legacy Next.js and Prisma codebase to Next.js 16 and Supabase, and I led the PHP to Next.js rewrite of HotNewHipHop.com. A rewrite starts with the current system and a decision on what to keep.
What happens after launch?
I can stay on for new features, fixes and performance work. I still work on two of the products above today.
Do you work with clients outside Canada?
Yes. I’m based in Montreal and work remotely with clients in the US every day.
