Bagerhat, Bangladesh - 11:55 pm local time
Full-Stack SaaS Developer building production B2B platforms where AI agents, Stripe billing, and multi-tenant architecture work together at scale. Top-Rated · $30K+ delivered · 5+ years building systems, founders scale without rebuilds — including a healthcare SaaS at 1,000+ patients with zero payment incidents.

WHAT I BUILD
End-to-end SaaS platforms — backend, frontend, AI agents, payments, infrastructure. Not a generalist who "also knows AI" or "also touches Stripe." A full-stack SaaS engineer whose AI and billing layers are the parts most teams underbuild.

→ Multi-tenant SaaS architecture with proper data isolation, RBAC, and tenant-aware billing
→ Subscription platforms with Stripe Billing — plans, proration, dunning, usage-based metering
→ Marketplace platforms with Stripe Connect — Standard, Express, and Custom accounts, deferred onboarding, split payouts
→ Production webhook infrastructure — idempotency, retries, dead-letter queues, signature verification
→ Authentication, authorization, customer portals, and admin dashboards
→ API design (REST + tRPC) with rate limiting, auth, and proper error handling

AI IN PRODUCTION SAAS
AI features are now expected in B2B SaaS. I build them as core capabilities, not bolt-ons:

→ Custom multi-LLM agents that complete multi-step workflows (onboarding, form processing, support automation)
→ OpenAI and Claude API integrations with cost controls, retry logic, observability, and fallback handling
→ Multi-model routing — the right LLM for each task (cheap models for classification, premium for reasoning)
→ Document-aware chat and RAG pipelines (pgvector), plus workflow assistants
→ Usage tracking and metered billing for AI features — the Stripe Billing + AI metering integration most teams ship broken
I understand the business side of AI features — token costs, latency, fallbacks, prompt observability, and how to bill for AI usage correctly.

PAYMENTS DEPTH
The Stripe billing layer is where most AI SaaS products break quietly — subscriptions that don't update, metered events that go unreported, and webhook handlers that fail to process dispute events.
I've shipped production payment systems across 7 gateways — Stripe (including Connect), PayPal, iXoPay, Dimoco, ACI Processing, emerchantpay, and PayBank2Bank. Real depth across subscription billing, usage-based metering, marketplace payouts, and webhook reliability.

RECENT WORK
→ catalyst-payment-app (B2B SaaS) — Custom multi-LLM agent for payments onboarding automation. Multiple models are routed for adaptive multi-step form completion. Stripe Connect with deferred KYC and multi-gateway fallback.
→ Inoqare (HealthTech SaaS) — Architected from zero. Multi-tenant healthcare platform serving 1,000+ patients with subscription billing and zero payment incidents in production.
→ Multi-step payment flow optimization (Marketplace) — Custom checkout retention flow that lifted payment conversion by 35%.
→ Gateway integration optimization — Diagnosed integration issues silently dropping conversions. +20% lift, pure infrastructure work.
→ Real-time SaaS platforms — Twilio-based chat, voice, and custom invoicing with integrated billing.
