Senior AI Full Stack Engineer

Techverx • Full time

Jan 2023 - Mar 2026 • 3 yrs 2 mos

Worked as a Senior AI Full Stack Engineer specializing in advanced AI-powered applications, automation systems, and intelligent SaaS platforms. My focus is on combining modern full stack development with artificial intelligence to build smart, scalable, and production-ready digital solutions for businesses. I design and develop AI chatbots, RAG (Retrieval Augmented Generation) systems, AI agents, and automation workflows that help businesses automate tasks, improve customer support, and enhance operational efficiency. These AI systems are built to understand business data and provide intelligent, context-aware responses. I work extensively with OpenAI API and large language models (LLMs) to integrate AI capabilities into web and mobile applications. I also implement vector databases such as Pinecone and FAISS for semantic search and knowledge-based AI systems that allow businesses to use their own data effectively. On the full stack side, I build modern applications using React, Next.js, Node.js, and Flutter, ensuring responsive UI, strong performance, and scalable architecture. I also design backend systems, REST APIs, and cloud-based infrastructures using Docker and AWS for production environments. Additionally, I specialize in AI workflow automation, connecting multiple services and systems to reduce manual effort and improve productivity. This includes building AI SaaS products, intelligent dashboards, and enterprise-level automation platforms tailored for business growth. This role allows me to deliver cutting-edge AI solutions that combine software engineering and artificial intelligence to create powerful, real-world applications that help businesses scale faster and operate more efficiently.

Sep 2018 - Dec 2022 • 4 yrs 3 mos

Worked as a Full Stack Developer responsible for building complete web applications, SaaS platforms, admin dashboards, and API-driven business systems. My role covered both frontend and backend development, along with database design, API integration, system architecture, and deployment. I developed modern, responsive, and interactive web applications using React and Angular, focusing on performance, scalability, and user experience. I built reusable UI components, dynamic dashboards, and single-page applications that improved business workflows and user engagement. On the backend, I worked with Node.js and Express to build secure REST APIs, authentication systems, and business logic layers.
