FAQ
Common questions, straight answers
Most of the things clients ask before kicking off a project.
How long does a typical project take?
Most MVPs ship in 6–10 weeks. Full SaaS builds take 3–4 months. Marketing sites and redesigns are usually 2–4 weeks. We agree a timeline before any work starts — and you get a working demo every Friday so there are no surprises.
Do you work with existing engineering teams?
Yes. I plug into your existing GitHub, Slack, Linear, or Jira. I can lead the build end-to-end, ship features alongside your team, or just be the senior reviewer on architecture-critical PRs.
What's included in post-launch support?
30 days of free bug fixes after launch. After that, a monthly retainer is the most common option — it covers maintenance, small features, performance work, and on-call support. You can also pay ad-hoc when issues come up.
Do you sign NDAs and IP transfer agreements?
Yes. I sign mutual NDAs before any sensitive details are shared. Code is yours from day one via your GitHub org — I sign IP-transfer language in the contract too, so there's zero ambiguity.
What time zones do you work in?
Based in India (IST / UTC+5:30). I overlap with US East Coast mornings, EU afternoons, and APAC business hours. Async-first by default with Slack or Linear, sync calls when decisions need to be made.
Do you handle hosting, infrastructure, and DevOps?
Yes. AWS (EC2, RDS, S3, Lambda), Vercel, Railway, Cloudflare, Docker, GitHub Actions — I set up production infra, monitoring, and CI/CD. You get a fully working production setup, not just code sitting on GitHub.
What if I only need part of a project?
That's fine. Frontend-only builds, backend API work, SEO audits, performance optimization, code reviews — I'll scope just what you need. No minimum project size, but most engagements start at 2 weeks of work.
Do you offer free consultations?
Yes. The first 30-minute scoping call is free, no commitment. If we're a fit, you'll get a written proposal within 48 hours covering scope, timeline, milestones, and a fixed quote.
Question not answered?
Send a quick message and you'll get a reply within 4 business hours.
