You will get AI SaaS MVP with Stripe Billing | Node.js + LLM API Integration
Project details
Building an AI SaaS MVP that actually ships? I build production-grade AI SaaS products with Node.js, Express.js | Nestjs, Next.js | React, Stripe, and OpenAI/Claude — typically 1-2 weeks from kickoff to live-Ready for signups.
You get a clean, scalable codebase, type-safe end-to-end (Zod, tRPC, Drizzle), with Stripe billing, auth, dashboards, and AI integrations that actually work in production.
I run my own SaaS, so I think like a founder. Async-first, Loom updates, no daily standups. Senior-engineer code quality. Spec-driven before any commits. Clean handoff with runbook included.

About Md. Khayrul Bashar
Senior Nodejs Engineer | AI SaaS MVP | Stripe API, AI Integration
Habigonj, Bangladesh - 1:00 am local time
I'm a senior Node.js engineer (6+ years) who builds AI-powered SaaS products from concept to live-paying-customer — fast, clean, and without the typical agency overhead.
What I ship for founders:
- AI SaaS MVPs (Node.js + Next.js + Stripe + OpenAI/Claude) — typically 1–2 weeks from kickoff to live
- Stripe billing — subscriptions, metered/usage-based billing, Stripe Connect for marketplaces, customer portal, webhook reconciliation
- AI integrations — OpenAI / Claude / Deepseek / Qwen / GPT — agents with tool use, RAG over your own data (pgvector / Pinecone), streaming chat, multi-agent workflows, MCP servers
- Type-safe end-to-end stack (Zod, tRPC, Drizzle) — fewer prod surprises, refactor without fear
- Auth + dashboards that actually work (JWT, OAuth2, magic links)
You'll like working with me if you want:
- A builder who thinks like a founder (I run my own SaaS, I know the stakes)
- Clean, scalable code, not just "make it work"
- Async-friendly, Loom-first communication
- Someone who pushes past generic AI-startup output — taste matters
Recent work:
🛠 Static.run — production-grade static-site hosting platform (Nest.js + Docker microservices + Nginx + AWS S3 multi-tenant). Scaled to 50K monthly users with zero downtime, 200+ paid customers in launch month, 35% server cost reduction via S3 + caching optimizations. CI/CD with GitHub Actions and canary deploys.
🛠 Lineicons v5 — icon platform handling 100K+ daily requests. Migrated off an expensive Cloudflare Worker to a custom Express.js VPS server with Redis caching, integrated Cloudflare R2 (S3-compatible) as the CDN, and built an internal S3-browser admin so non-technical staff can manage the icon library without engineering involvement.
🛠 so-me.studio — multi-tenant SaaS scheduling product where I'm lead engineer and co-owner. Stripe-billed subscriptions, MCP tool layer + REST API for AI-agent integrations, infrastructure I own end-to-end (devops, deploys, on-call). Live with paying customers.
🛠 ai-seo-boost (flowappz) — my latest production contribution at flowappz: an AI content/SEO automation product for Webflow sites. Pipeline of LLM calls + structured content generation + scheduling, built for non-technical Webflow operators.
Tools I use daily:
Bash + Linux, Claude Code, GitHub Copilot, Stripe Dashboard, Vercel, Railway, Hetzner, Docker, n8n, Make, Linear, Loom.
How I work:
1. Short kickoff call or async writeup — I push back early if scope, budget, or stack feels off.
2. Spec-driven — 1-page spec before any code: what we're shipping, what we're not, success criteria.
3. Daily Loom + written updates — no surprise demos, no silent weeks.
4. Working demo at every milestone, deployed to a staging URL you can click around.
5. Clean handoff: repo, env, runbook, and a short Loom walkthrough so future you (or your team) isn't lost.
FAQ:
Q: What's a realistic timeline for an MVP?
A: For a Stripe-billed AI SaaS with auth + dashboard + 1–2 AI flows: 3–5 days for a Basic scope, 2–3 weeks for Standard with multi-tier billing and onboarding flow. Larger systems (multi-agent, white-label, marketplace) take 3–6 weeks.
Q: Do you handle ongoing maintenance after launch?
A: Yes — usually as a fractional/retainer arrangement after the initial build. Typical retainer: 10–15 hrs/week for active product evolution. I'm not a "build and disappear" engineer.
Q: Can you work inside my existing repo / team?
A: Yes. Comfortable in Git workflows, code review etiquette, async communication. I work alongside existing engineers, junior or senior — not as a replacement for them.
Q: What about NDAs and IP?
A: Standard mutual NDA before discussing specifics is fine — I sign them routinely. Default IP arrangement: you own everything I build for you.
Q: Why is your hourly rate $70/hr when older Upwork jobs show lower rates?
A: The older work history on this profile is from 2019 when I was establishing on Upwork. Current positioning: senior engineer with 6+ years of post-bootcamp production work, running my own SaaS (so-me.studio) and contracted at multiple startups since 2019.
Q: What's "not a fit" for working with me?
A: I'm not the right fit if you need pixel-perfect Figma handoff (I'm a system designer, not a designer), if you want a $5/hr-style WordPress contractor, or if you need someone on Zoom every day. I work best async, Loom-first, with builders who care about shipping.
Let's get your MVP live this month, not next quarter. Send a short message about what you're building — I'll tell you honestly if it's a fit.

Kickoff + spec
Short async writeup or 20-min call. I push back early on scope, budget, or stack if needed. Output: 1-page spec listing what we ship, what we do not ship, and success criteria.
Ideation & Roadmapping
Based on our discussion, I’ll create a simple technical roadmap with suggested architecture, tools, and milestones. You’ll get a clear picture of what will be built, when, and why.
