You will get a production-ready Next.js & TypeScript web app built for you
Top Rated
Project details
I build production-ready web applications using Next.js, TypeScript, and modern web technologies — from high-converting landing pages to complete SaaS MVPs with authentication, payments, APIs, and deployment included.
Every project is built with scalability and maintainability in mind from day one. I follow clean architecture, strong TypeScript practices, organized folder structures, and modern UI development using Tailwind CSS. I leverage Server Components, Client Components, and performance best practices to deliver fast, reliable applications.
What I can build:
• Landing Pages & Marketing Websites
• SaaS MVPs & Full-Stack Applications
• Admin Panels & Internal Tools
• Dashboards & Analytics Platforms
• Stripe Payment Integrations
• Supabase & Firebase Backends
• REST & Third-Party API Integrations
• AI-Powered Features, AI Agents, and Automations using OpenAI, Claude, Gemini, and other leading AI providers
• Authentication & User Management
• Deployment & Production Infrastructure
My focus is not just writing code that works today, but building software that remains easy to maintain, extend, and scale as your business grows.

Cloudflare Workers expert needed LLM visibility setup for B2B site
Hired Biplob to build a Cloudflare Worker that serves clean Markdown versions of our Webflow pages for AI search visibility (ChatGPT, Claude, Perplexity citations). He delivered well beyond scope at a very fair price.
What made him stand out:
— Before I even hired him, he had already deployed a working prototype on my actual site content. No other applicant did this. It removed the main risk of the engagement.
— Technically sharp. He correctly identified that the naive HTML→Markdown approach would hit Cloudflare Workers' CPU limits, and architected around it using HTMLRewriter streaming + a lightweight conversion pass. He explained the trade-offs clearly to a non-technical client.
— The final deliverable went past the brief: hand-tuned stripping for Webflow-specific quirks (button hover duplicates, slider image dedup, responsive variants), locale-aware routing across five language versions, robust 404 handling, a documented purge mechanism, proper test coverage, and clear inline documentation. Code was clean, modular, and well-commented.
— Communication was excellent throughout. Responsive (usually within hours), raised design decisions proactively (framework choice, route conventions, edge cases), and asked the right clarifying questions before building. Made the engagement easy to manage from my side.
— Honest about scope and time. Took ownership of the parts that needed coordination on my side (DNS) without scope creep.
Would hire again without hesitation, and have him in mind for future Cloudflare/edge/AI-visibility work. Recommended.

Deploy & Polish a Static Portfolio Site (HTML/CSS/JS)
Biplob was responsive throughout the project and committed to finding solutions when challenges came up. He took initiative from the start — building a working demo before even being hired — and communicated clearly at every stage. Would recommend for front-end development work.

Need to develop a Single page web app and API for handwritten digit recognition
Nibir is one of the best developers that I've worked with.
Don't judge him based on his communication skill, he is a lot better and knows how to get things done, writes clean code and also provides recommendations.

Job Success

That's the moment most founders feel stuck between two bad options: start over, or hire someone who doesn't understand what the AI built.
I'm the third option. I read AI-generated code, I understand what it was trying to do, and I fix it — fast and properly.
This is what I do:
— Email & verification issues: signup codes not arriving, SMTP broken, Resend or SendGrid misconfigured — I've fixed all of these.
— Broken auth: Supabase Auth, Firebase Auth, BetterAuth, email/password flows, OAuth, Row-Level Security — set up correctly the first time.
— Vibe-coded app rescue: audit the codebase, find what's insecure or broken, refactor for production.
— Full-stack SaaS and MVPs: Next.js, React, Supabase, Firebase — built from scratch with auth, payments, and deployment ready on day one.
— AI integrations: OpenAI, Claude, Google Gemini, Groq, Mistral, xAI Grok, DeepSeek — via REST API or Vercel AI SDK.
— Payments: Stripe, Polar, PayPal, Paddle, Creem — subscriptions, one-time payments, webhooks.
— Deployment: Vercel, Netlify, AWS, GitHub Pages — domain, SSL, CI/CD, mobile-checked.
— Static sites and landing pages: Astro, HTML/CSS/JS — deployed and connected to your domain in hours.
Tech I use every day:
Vibe tools: Replit, Lovable, Bolt, Base44, Manus AI, Claude Code, Cursor, v0
Frontend: Next.js, React, Astro, Tailwind CSS, Shadcn UI
Backend: Hono.js, Node.js, Express, FastAPI
Databases: Supabase, Firebase, PostgreSQL, MongoDB, PrismaORM, Drizzle
AI: OpenAI, Anthropic, Google Gemini, Groq, Mistral, xAI, DeepSeek, Vercel AI SDK
Email: Resend, SendGrid, Nodemailer
Payments: Stripe, Polar, PayPal, Paddle, Creem
Auth: Supabase Auth, Firebase Auth, BetterAuth
Languages: TypeScript, JavaScript, Python
Deploy: Vercel, Netlify, AWS, GitHub
