About

Professional summary

I am a full-stack developer and AI automation engineer with more than six years of experience building software for banking, fintech, B2B marketplaces, and SaaS products. My core expertise is the MERN ecosystem, Python services, and modern React-based front ends.

I build end-to-end systems, from responsive interfaces and REST APIs to databases, authentication, integrations, deployment, and production support. I have delivered solutions using Node.js, Express, FastAPI, React, Next.js, MongoDB, PostgreSQL, Redis, and TypeScript.

I have led a team of eight engineers on a production core banking platform, owned releases delivered to bank clients, and served as a first responder for production issues. I am comfortable translating direct client requirements into technical designs and executable delivery plans.

My recent work includes Video KYC infrastructure with live WebSocket sessions, an encrypted digital asset vault, an AI-powered lead-capture SaaS, SEO content automation, and a large-scale Angular-to-React SSR migration for a live marketplace.

I take ownership beyond application code, including Dockerized environments, GitHub Actions CI/CD pipelines, AWS EC2 deployments, PM2, nginx, release cutovers, and rollback documentation. I use AI-assisted development tools such as Claude Code, Google Gemini, and Codex for implementation, debugging, testing, and documentation.

I enjoy building reliable, secure, automation-focused products and mentoring junior engineers through task breakdown, design decisions, code delivery, and problem solving.

Career history

Full Stack Developer Rath Infotech

I own full-stack delivery across internal CRM, operations, marketplace, fintech, SEO automation, and AI lead-capture products. For Spectra, I own features across six modules, including the sales CRM pipeline, Lead 360, sales intelligence, a command palette, a multi-currency quotation engine with GST rules and approval workflows, a Jira-style task module, and an ATS/recruitment module.

I built and contributed to multiple FastAPI, Node.js, React, Next.js, and PostgreSQL systems, including an AI lead-capture SaaS, a citation-verified SEO brief engine, an encrypted digital asset vault, and an investment-data platform. I led a live Angular-to-React 19 SSR migration, built Docker and GitHub Actions pipelines, and support AWS EC2/PM2/nginx deployment cutovers and rollbacks. I also guide three junior engineers through task assignment, design decisions, and technical blockers.

Software Developer Finacus Solutions

I built the Video KYC platform backend end to end using Node.js, Express, and MongoDB, delivering 149 REST endpoints across 14 data models. I implemented live video WebSocket sessions and recording, JWT authentication with refresh tokens, role-based access control, geo-IP checks, and Swagger documentation for customer and administrative React applications.

I owned core banking modules including Account Master, Voucher, Cheque Truncation System, and 2FA across API and UI layers. I reduced cheque-processing time from eight seconds to two seconds, led eight engineers on a banking platform with approximately 1,400 React and Redux screens, gathered bank-client requirements, owned releases, responded to production incidents, and delivered a bilingual AML compliance application.

Web Developer D-web Technologies

I developed a complete school website using HTML, CSS, and JavaScript. The site included pages for admissions, gallery, courses, events, and other institutional content.

I also created an administrative panel that enabled teachers to manage data and integrated APIs to support dynamic updates and improved site automation.

Web Developer Innodatatic Inc

I built and maintained responsive web applications for the organization. My work focused on delivering functional, accessible interfaces across web pages and application features.

I improved application load times through code optimization and image compression, helping improve the overall web experience and performance.
