With 13+ years of experience, I architect end-to-end solutions that scale. I played a key role in transforming a growth marketing platform into a million-dollar business by merging full-stack expertise (MERN/MEAN) with cloud-native architecture on AWS.
I now specialise in high-impact AI Automation—building autonomous agents and RAG-based systems that transform operational efficiency. From custom LLM integrations (GPT-4o/Claude) to seamless CRM syncs (Salesforce/HubSpot), I deliver secure, enterprise-grade tech that drives demand and cuts costs. Let’s build the future.

FAQ
Do you handle server setup and deployment?
Yes. I specialize in server configuration for AWS, DigitalOcean, and other VPS providers. I can set up your environment from scratch, optimize it for performance, and ensure your API or web app is deployed securely with SSL and firewall protection.
Will I receive documentation for the API or custom code?
Absolutely. I provide detailed technical write-ups and API documentation (using Swagger or Markdown) for all complex integrations. This ensures your front-end team or future developers can easily understand and maintain the backend architecture.
Which technologies do you use for backend development?
I am an expert in Node.js (Express), PHP, and JavaScript. For databases, I work with MySQL, MongoDB, and Firebase. I choose the stack that best fits your project’s scalability and performance requirements.
