About us
A small team, and you always know who’s doing the work.
DebugSwift is an AI automation and software development agency in Kolkata, working with businesses here and internationally. It’s led by Rijaul Sk, who takes every first call and works on every build, alongside a small team of specialists across design, engineering, automation, and growth. You are never handed to someone you haven’t met.
Why we're called DebugSwift
Debugging businesses swiftly.
Swifts are birds that catch insects in mid-air, faster than any bird in level flight. That’s how we work. In software, a problem is called a bug, and anything quietly costing your business is a bug too. We find it and fix it, quickly.
No months of meetings and no long presentations. Just a free call, a fixed price, and a fix that’s done in days.
This is Deb. Deb catches bugs.
How we work
Start small. Prove it works. Then do more.
Most agencies want your biggest project first. We work the other way round: start with the smallest fix that pays for itself, prove it works, then earn the next conversation.
A free diagnosis first.
Twenty minutes on what's going wrong. If the fix isn't worth your money, we'll tell you.
A fixed price, then the work.
In writing, before anything starts. We never charge by the hour.
Built in days, not months.
You'll see something working within the first week.
You own everything.
Your accounts, code and content stay in your name. Nothing breaks if you stop working with us.
Specialists when needed.
Extra hands join per task when a build needs them, and your point of contact never changes.
Who we are
The person you talk to builds it.
You will never be handed to someone you haven't met. If a specialist joins your project, you'll be told who and why, and I'm still the one who answers the phone.
I'm Rijaul, an engineer from the southern edge of Kolkata. I started DebugSwift because the fastest way to help a business is to fix one specific thing it's bleeding money on, prove it worked, and earn the next conversation. I take every first call myself, and I'm on every build we ship, not as a name on a proposal, but as the person writing the thing.

Founder, and the engineer on your build
The team
A small team, with the skills you need.
These are the skills we bring to a project. A specialist joins only when the work needs them, and we'll tell you who and why.
Graphic design
The visual system: brand marks, layouts, and the rules that make everything you ship look like one deliberate company.
Frontend engineering
The pages and interfaces your customers actually touch: fast on every screen, without the bloat that makes a site feel slow.
Backend engineering
The part you never see and can't afford to lose: databases, APIs, and the logic that keeps your data correct and safe.
DevOps
Hosting, deploys, backups, monitoring. The reason the thing we shipped is still running months later, in accounts you own.
AI engineering
The assistants themselves: prompts, guardrails, testing. Answers that stay inside the wording you approved, at 2am as at 2pm.
Automation
The wiring between your tools: enquiry to sheet, order to invoice, question to booked slot, so the busywork runs itself.
SEO
The structure that makes you findable when someone nearby searches for what you sell: profile, pages, reviews, plumbing.
…and whatever your project needs next. Your point of contact never changes.
