I'm Nobin, a Full-Stack Product Developer with 5+ years of experience helping startups and businesses build scalable SaaS platforms, AI-powered applications, CRM systems, and custom web solutions.
Throughout my career, I've worked with leading IT companies and development teams, delivering secure, high-performance software tailored to real business needs.

Have an idea? Let's build it together.

FAQ
Do I need a complete specification before contacting you?
Not at all. If you only have an idea for a CRM or SaaS product, I'll help define the features, choose the right tech, and recommend the best package before we begin.
Can you build a complete SaaS or CRM product from scratch?
Yes. I can build the frontend, backend, database, authentication, dashboards, user roles, APIs, and integrations required for your agreed scope.
Can you improve or continue an existing CRM or SaaS application?
Absolutely. I can add new features, optimize performance, fix bugs, or modernize an existing CRM or SaaS product.
Can you migrate my existing CRM data or connect to tools like HubSpot or Salesforce?
Yes. I can import your existing contact/lead data and set up integrations with third-party CRMs or marketing tools via their APIs, so you're not starting from a blank database.
How do you handle multi-user roles and permissions in a CRM?
I build role-based access control (admin, manager, sales rep, etc.) so different users see and edit only what they should — standard for any CRM used by a team.
Do you build AI-powered web applications and custom integrations?
Yes! I build custom AI web apps using OpenAI APIs, Anthropic Claude, LangChain, and modern stacks like Next.js, Node.js, and Python.
Which AI provider do you use, and what about data privacy and API costs?
I typically integrate OpenAI or Claude depending on your use case, and I'll recommend the best fit for your budget. I design integrations so your data isn't retained beyond what's needed, and I'll give you a clear API cost estimate before we build.
Will my application be scalable as my business grows?
Yes. Every tier is built on a scalable architecture, so new features and future growth don't require a rebuild.
Can you sign an NDA?
Yes. I'm happy to sign a Non-Disclosure Agreement before discussing confidential business ideas.
Do you provide deployment support?
Yes. I deploy to your chosen cloud platform and help configure your production environment before handing off.
