I'm Shuvo — a senior full-stack developer (10+ years · React, Next.js, Node, Sanity). I rescue AI-generated builds that break in production and ship scoped features for founders and small teams. My portfolio is the interview: pick an offer, book a time, and your first hour with me is already paid work.
Remote · GMT+6 with US/EU morning overlap · replies within hours
Every engagement starts small and scoped, so there's zero hiring risk. Prices are public on purpose — you shouldn't need a sales call to know what things cost.
Your AI-built app is broken, stuck, or fragile? We screen-share, I diagnose it live and either fix it on the call or hand you a prioritized fix plan.
One stalled or fragile AI-generated feature made production-ready — state, auth, APIs, error handling — delivered as a clean PR.
Lighthouse & speed audit on your key route, plus the top fixes shipped. I ship 95+ Lighthouse routinely — this site scores 100.
Schema design, content types, and page templates — structured content with SEO built in, by the author of a published Sanity plugin.
One well-defined React/Next.js feature, end to end — from requirements to a reviewed PR with a handoff doc your team can build on.
Keep a senior developer on call for your product — features, fixes, reviews, and AI-workflow help on clear milestones.
Four steps. No screening rounds, no take-home tests, no proposals ping-pong.
Pick a time on Calendly. No interviews, no coding tests — your first hour with me is paid work, not a screening.
We screen-share. I find the problem or scope the feature, and you get a fixed price in writing the same day.
Fixed scope, 50% to start. Clean code, async updates, US/EU morning overlap from GMT+6.
You get a PR, a short handoff doc, and a prioritized “what I'd do next” — continue only if it's worth it.
Real outcomes from shipped work — and public code you can verify yourself before spending a dollar.
Built multi-agent AI workflows and a Canva-style presentation editor. Redesigned the upgrade flow — conversions tripled. This is where I learned to make AI products actually shippable.
Real-time streaming with LiveKit + Supabase, JWT/OAuth auth for 1,000+ users, and Postgres queries cut from 200ms to 50ms under load.
A Sanity schema-markup plugin (on sanity.io/plugins), a Gmail MCP server for AI agents, and Remotion Captioneer for word-synced video captions.

Ten years of shipped work, live projects, and open-source code answer the questions an interview would. Instead of a free screening process, we start with a small paid scope — you risk $150, not a hiring mistake. If the first session finds nothing actionable, it's free.
Sessions are paid at booking. Fixed-scope sprints are 50% to start, balance on delivery — via Stripe, Wise, or bank transfer. You approve the scope in writing before any work begins.
React, Next.js, Node.js, TypeScript, Sanity & Payload CMS, Supabase/PostgreSQL, MongoDB — plus AI product workflows (OpenAI, Claude, multi-agent systems) and Remotion programmatic video. AI-builder cleanups: Cursor, Lovable, v0, Bolt, Replit.
I'm in Dhaka (GMT+6) and deliberately overlap US and EU mornings. Most clients get same-day turnarounds because I'm working while you sleep.
That gap is exactly what I fix — and finding out costs $150, refunded if I can't help.
