About
I design and build production-ready software systems that turn complex business ideas into reliable, high-performing products. Over 5+ years I've delivered across print-on-demand, e-commerce, ed-tech, analytics, and enterprise automation — owning everything from system architecture and cloud infrastructure to backend services and frontend experiences.
I'm at my best on problems involving scale, performance, distributed systems, integrations, and applied AI — building systems that stay fast, fault-tolerant, and maintainable under real-world load.
What I Do
Full-Stack SaaS Build
End-to-end product development, from architecture to deployment. I own every layer so you can focus on the product.
- Nuxt / Vue / React frontends
- NestJS / Node.js backend APIs
- Multi-tenant database architecture
- AWS infrastructure + CI/CD
- Auth, billing (Stripe), notifications
Backend APIs & Systems
High-performance, scalable backends. REST or GraphQL, built for throughput, reliability, and maintainability.
- REST / GraphQL API design & build
- Real-time with WebSockets / WebRTC
- Database design & optimization
- Microservices & event-driven architecture
- Redis caching, queues, pub/sub
Cloud & DevOps
Production-grade infrastructure. Automated deployments, zero-downtime releases, and real observability.
- AWS architecture design
- Docker & container orchestration
- Terraform infrastructure as code
- CI/CD pipelines (GitHub Actions)
- Monitoring, logging, alerting
Integrations & Automation
Connect your stack and automate operations — Shopify, NetSuite, Stripe, and custom pipelines wired together.
- Shopify / e-commerce integrations
- NetSuite ERP & payment gateways
- Workflow automation (webhooks, queues)
- Web scraping & data pipelines
- Third-party API integrations
Performance Audit & Fixes
Slow app? I diagnose and fix. Core Web Vitals, N+1 queries, memory leaks — find the bottleneck, eliminate it.
- Core Web Vitals audit & fixes
- SSR / SSG optimization
- Database query optimization
- CDN & caching layers
- Load testing & profiling
Applied AI & RAG
Practical LLM features in real products — retrieval, agents, and guardrails that actually ship to production.
- RAG pipelines (ingest → embed → retrieve)
- Multi-LLM integration (OpenAI, Gemini)
- LangChain / LangGraph orchestration
- Prompt design with safety guardrails
- AI workflow automation
Selected Work
Render Engine
Print-on-demand mockup generation at scale
A serverless, API-first rendering pipeline that automates massive print-on-demand workflows — turning uploaded designs into photorealistic, print-accurate mockups with GPU-accelerated canvas distortion and warp, plus optional 3D via Three.js.
Egshop
egshop.ioMulti-tenant commerce platform
A Shopify-like SaaS where merchants launch themed storefronts with custom domains, an app store, and subscriptions — including complex billing, wallets, and local logistics integrations, optimized to stay fast at scale.
TaskGrid
taskgrid.ioReal-time project management SaaS
A project and task management platform architected for high concurrency — real-time sync, team collaboration, file sharing, and productivity analytics, built to stay responsive as teams and workloads grow.
Campus Automation System
just.edu.bdUniversity-scale management platform
Partially architected and led development of a nationwide university management system serving 120K+ students and staff. Centralized academic and administrative operations — the public university site, role-based dashboards for students, teachers, and officers, admission and job portals, results, and payments — behind scalable backend services.
Duke Supply
NetSuite-powered e-commerce
An e-commerce platform driven by NetSuite ERP data, with automated real-time synchronization of products, inventory, customers, and order workflows between the ERP and the storefront.
Craft Music
craft-music.devGlobal real-time music learning
A worldwide ed-tech platform that solved global audio latency and synchronization using WebRTC — live lessons, timezone-aware scheduling, multi-currency payments, and real-time chat for instructors and students.
Enterprise Automation
Forecasting & budgeting automation
Replaced legacy spreadsheet processes for an enterprise forecasting and budgeting system with Python-driven data imports, repeatable workflows, real-time dashboards, and exportable reports.
Also: Shopify apps (product duplication, discount management) · Pengine (POD data migration & search) · eSelfmade (EdTech course platform).
Experience
Software Engineer
Genesys Softwares
- Lead engineering teams of 5–6 developers, owning system architecture, technical direction, and code review across multiple SaaS platforms.
- Built and scaled a serverless rendering pipeline handling 50K+ daily requests, cutting high-resolution render time from 40s+ to under 10s at 99.99% uptime.
- Co-architected a multi-tenant commerce platform — themes, custom domains, billing, wallets, and logistics — and optimized search to handle large per-tenant catalogs (10K+ products).
- Architected a real-time project-management SaaS with live sync, collaboration, and analytics, built to stay responsive under heavy concurrency.
- Integrated enterprise systems end to end: NetSuite ERP-powered e-commerce, Shopify apps, and Python-driven forecasting that replaced legacy spreadsheet workflows.
- Designed CI/CD pipelines, Dockerized deployments, and fault-tolerant architectures (retries, failure isolation, caching, safe degradation) for bursty, high-volume workloads.

FAQ
Do you work on SaaS or startup products?
Yes. I've built and scaled SaaS platforms, internal tools, and early-stage startup products with a focus on long-term maintainability and performance.
Do you work remotely?
Yes. I'm experienced working with distributed, remote-first teams across different time zones.
Do you build AI-enabled applications?
Yes. I integrate LLMs into production systems using RAG, embeddings, and structured prompt pipelines for reliable, scalable AI features.
How do you usually start an engagement?
Often with a short discovery call or a focused repo audit to find the highest-impact work, then we agree on clear milestones from there.
