You will get a custom web app or client portal in Next.js for your business


Project details
Stop forcing your business into someone else's SaaS. I will build a custom web app or client portal that fits exactly how your business already works — bookings, payments, client logins, internal dashboards, admin panels, or whatever else you need.
Built with React, Next.js, Node, and PostgreSQL. Fast, mobile-friendly, secure, and clean enough for your team to use without training. You own the code, the database, and the deployment.
Best for: SMBs replacing $200+/month SaaS stacks, agencies needing a client portal, service businesses needing custom booking or intake systems.

About Md Mahabub Ul Alam
Fullstack Developer | MERN, Next.js | n8n & AI Automation Expert
Narayanganj, Bangladesh - 5:20 am local time
I do two things:
1. Build. Custom web apps, client portals, dashboards, and SaaS tools in React, Next.js, and Node. Plus Shopify, WooCommerce, and WordPress sites that load fast and convert.
2. Connect & automate. GoHighLevel, HubSpot, AWeber, Mailchimp, Klaviyo, ActiveCampaign, ManyChat — wired together with n8n, Make, or Zapier. AI (OpenAI, Claude) where it actually helps: lead qualification, support replies, document processing.
What that gets you:
- 10–30 hours/week back from manual work
- Lower software bills (most clients cut Zapier and overlapping tools by 60%+)
- A website or app your team can run without calling a developer
- AI features that work in production, not fragile prototypes
How working with me feels:
- Fixed scope and price before I write any code
- I will tell you no if a $30/month tool already does it
- You own the code, the accounts, and the documentation
- First call is 30 min, free, no pitch
The tools behind the work:
- Web apps & sites: React, Next.js, Node.js, TypeScript, MongoDB, PostgreSQL, Tailwind. WordPress and Shopify when that is the right answer; custom-coded when it is not.
- E-commerce: Shopify, WooCommerce — checkout fixes, custom themes, app integrations, performance work.
- CRM & marketing: GoHighLevel, HubSpot, Salesforce — setup, automation, custom integrations.
- Email: AWeber, Mailchimp, Klaviyo, ActiveCampaign — flows, segmentation, deliverability cleanup.
- Automation & AI: n8n, Make, Zapier, ManyChat. OpenAI and Claude APIs. Custom AI agents and chatbots trained on your own docs (RAG), not generic GPT wrappers.
The stack matters less than whether the thing solves the problem and keeps running. That is what I optimize for.
Send a short message about what is broken or slow. I will reply within a few hours with a real plan or an honest "not my fit, here is who is."
