What kind of work do you do?

I help startups and businesses build scalable SaaS products, automate workflows with AI, integrate powerful APIs, and ship full-stack features from database schema through deployment. That includes admin dashboards, real-time portals, CRM integrations, and Meta API chatbots.

What's your primary tech stack?

React, Next.js, and TypeScript on the front end with Node.js and Express on the back, plus PostgreSQL or MongoDB. I also work with Socket.io, Prisma, AWS S3, Vercel, and automation tools like n8n and Zapier.

Dhaka, Bangladesh. I'm open to remote roles and currently work with a Canada-based team at Biz Growth Lab Ltd alongside my role at DataVro Agency.

ZiloChat (WhatsApp Business SaaS at zilochat.io), the RPL Automation Platform for RPL.it Australia, the DataVro agency site at datavro.org, growth builds like Qila Capital and MediaZilla, and an Eventbrite lead automation stack in n8n with Apify, Claude, and Gmail outreach.

Do you build real-time features?

Yes. I've implemented Socket.io messaging, live conversation updates, event-driven automation, and role-based access across production portals such as RPL Automation and ZiloChat.

Do you do growth engineering too?

Yes. Alongside product development, I work on technical SEO, GEO, and AEO, CRM automation, conversion funnels, and structured data workflows for search and AI discovery, especially for SaaS products at Biz Growth Lab.

What's your academic background?

B.Sc. in Computer Science and Engineering from University of Asia Pacific (CGPA 3.91/4.00), graduated June 2025. Dean's Honor and Vice Chancellor's Awards recipient.

Any research experience?

Leadership outside coursework?

Served as Vice President of the Research & Publication Unit at CSE Club (2024 to 2025), leading research initiatives and co-organizing the Intra-University Research Expo 2025.

Are you open to new opportunities?

Yes. I'm interested in full-stack engineering roles, SaaS product work with startups and businesses, and projects involving AI automation, API integration, or growth engineering.

Do you take freelance or contract work?

I consider select contract engagements for full-stack SaaS builds, AI workflow automation, CRM integrations, and technical SEO or GEO projects. Reach out with scope and timeline.

How do you prefer to collaborate?

I work well async with ClickUp and Confluence documentation, regular status updates, and clear module ownership. Happy to lead features or join an existing team.
