What's your tech stack, and why?

Next.js, TypeScript, Tailwind, PostgreSQL (Neon or Supabase) with Drizzle ORM, Better Auth, Stripe or Polar.sh for billing, and Vercel for hosting. It's a modern, production-proven stack that's fast, type-safe, SEO-friendly, and easy for any developer to maintain after handoff.

How do payments and milestones work?

Projects start with a 50% deposit, with the balance tied to milestone deliveries and a final payment at handoff. You see working progress at each milestone, so you're never paying for a black box.

What happens after launch, and do you offer ongoing support?

Every project includes a 30-day post-launch support window. After that, optional month-to-month retainers cover maintenance, new features, and priority support, starting at $400/mo.

Can you take over, fix, or rebuild an existing project?

Often, yes. I can audit an existing codebase, fix or extend it, or rebuild it on a modern stack if it's holding you back. Send me what you have and I'll tell you honestly whether a fix or a rebuild makes more sense.

I build web products that work.

Q: Do you use AI to write the code?

I use AI coding assistants as part of my workflow, but every line that ships is reviewed, tested, and owned by me. You're paying for architecture decisions, judgment, and accountability, not raw keystrokes.

Solo = Fast

Production-ready

Auth, payments, privacy compliance (PIPEDA / PCI / GDPR), and cloud infra, all handled.

04 · About

Built since 2013. Owned, line by line.

hi, I'm JoelBuilding since 2013

I'm Joel Stain Lobo, a full-stack developer based in India building web products for clients and markets in the US, UK, Canada, and Australia.

I've been writing software since 2013 and spend most of my time either building client projects or shipping my own SaaS products. I care about clean architecture, real compliance (not checkbox compliance), and outcomes over outputs.

On AI tooling: a transparency note

I use AI coding assistants as part of my workflow, primarily Claude Code for development, and other models for copy, research, and generation. Every line that ships is reviewed, tested, and owned by me. You're paying for judgment, architecture decisions, and accountability, not just keystrokes.

I work with a small number of clients at a time, so your project gets full attention.

Nothing is outsourced or handed to a team. I personally architect, build, and ship every project end to end.

05 · FAQ

the questions I actually get ↓

Questions, answered straight.

The things people ask before we start. If yours isn't here, just ask. I reply within 24 hours.

Custom websites start at $1,500, custom web apps at $4,000, and SaaS MVPs at $8,000 USD. Every project is scoped individually and quoted as a fixed range before any work starts. No hourly surprises and no 'contact for pricing'.

A custom website is typically 1–2 weeks, a custom web app 3–6 weeks, and a SaaS MVP 6–10 weeks. Timelines depend on scope and how quickly feedback comes back, and you get a written timeline with milestones before we begin.

Yes. You own 100% of the code, the design, and the IP on final payment. Everything is delivered in your own GitHub repository and deployed to your own hosting accounts. There's no lock-in and nothing held hostage.

I've worked with Western-market clients for years and keep overlapping hours for calls, reply to messages within 24 hours, and run everything through written scope docs and async updates. Time-zone difference becomes an advantage: work often progresses while you sleep.
