The Agency
Big enough to build it. Small enough that you know who did.
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 diagnosis 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 "DebugSwift"
Debugging businesses swiftly.
Real swifts are aerial insectivores — they catch bugs in flight, faster than any bird in level flight. That’s the whole philosophy: anything quietly costing your business is a bug. Find it, fix it, move.
No six-month discovery phases, no decks about your “digital journey” — a diagnosis, a fixed price, and a fix that ships in days.
This is Deb. Deb catches bugs.
The Method
Small fixes first. Trust before big projects.
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.
Diagnosis before proposal.
Twenty minutes on where it hurts. If the fix isn't worth your money, you'll hear that on the call.
Fixed price before work.
In writing, before anything starts. Never hourly.
Build in days, not quarters.
Something working ships within the first week. You watch it happen.
Handover, not hostage.
Accounts, code, and content stay in your name. Nothing breaks if we part ways.
Specialists on demand.
Extra hands join per task when a build needs them — your point of contact never changes.
Who's Behind It
Built by the person you'll talk to.
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 diagnosis call myself, and I'm on every build we ship — not as a name on a proposal, but as the person writing the thing.

The Bench
A small team. Every discipline named.
We're not a crowd, and we're not one person either. These are the hands a build can call on — a specialist joins when the work genuinely needs them, and you're told who and why. Nobody is billed to your project to look busy.
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 build needs next. Vetted specialists join per task — and your point of contact never changes.
