I build AI-powered applications, intelligent automation systems, and full-stack web platforms that help businesses reduce manual work and streamline their operations. I build AI voice agents for inbound and outbound calls, customer support, lead qualification, appointment booking, follow-ups, and other business workflows. I develop AI chatbots and AI agents using OpenAI, LangChain, prompt engineering, tool and function calling, API integrations, and custom business logic. I design end-to-end AI automation workflows that connect AI agents with CRMs, databases, email, WhatsApp, APIs, and other business systems. I build workflow automations using n8n, Zapier, and Make, including webhook-based triggers, API integrations, data processing, conditional logic, scheduled jobs, and multi-step workflows. I also develop full-stack web applications using the MERN stack (MongoDB, Express.js, React, and Node.js), including REST APIs, authentication, RBAC, real-time WebSocket features, dashboards, and database architecture. I automate repetitive business processes such as lead intake, lead qualification, lead routing, CRM updates, notifications, data synchronization, reporting, payroll calculations, and document generation. I integrate OpenAI and other AI services with existing software, third-party APIs, CRMs, databases, communication platforms, and internal business systems. My focus is on building practical AI solutions that can understand inputs, make decisions, call tools and APIs, update systems, and execute complete business workflows automatically.

Web Developer(AI Focused)

TechOverflow • Full time

I worked on Elevora, an SEO platform where I developed multi-tenant backend systems and AI-powered SEO automation features. I built scalable REST APIs using Node.js and PostgreSQL, implementing multi-tenant architecture, authentication, data management, and backend services to support multiple organizations and users. I developed a React.js dashboard for managing SEO workflows, monitoring jobs, tracking real-time processing status, and visualizing results through a responsive web interface. I designed and integrated AI-powered SEO systems using LangChain, Retrieval-Augmented Generation (RAG), and Pinecone vector databases to provide context-aware analysis and intelligent content retrieval. I built RAG pipelines that processed and retrieved relevant SEO data with sub-2-second retrieval times, significantly improving the speed and efficiency of automated SEO audits. I automated SEO auditing and analysis workflows using AI, reducing the time required for manual SEO audits by approximately 90%. I also worked on integrating AI capabilities with backend APIs and automation workflows, enabling the platform to process SEO data, retrieve relevant context, generate intelligent insights, and deliver results through the web dashboard. My work focused on combining scalable backend architecture, real-time web applications, vector search, LLMs, and AI automation to build a faster and more intelligent SEO platform.

Blockchain Intern

Vanar • Part time

May 2024 - Aug 2024 • 3 mos

I worked on blockchain development and Web3 technologies, focusing on integrating blockchain functionality with modern web applications and backend systems. I developed blockchain integrations using Node.js and ethers.js, working with smart contract interactions, wallet connections, transaction handling, blockchain providers, and on-chain data. I explored practical Web3 development workflows, including connecting decentralized networks with backend APIs, interacting with smart contracts, reading and writing blockchain data, and handling blockchain transactions programmatically. I also worked with blockchain integration tools and technologies to understand how decentralized applications can be connected with existing web platforms and backend services. My focus was on building a practical understanding of blockchain development and implementing Web3 functionality using JavaScript, Node.js, and ethers.js.
