About

Professional summary

I am a full-stack software architect with more than 11 years of experience building enterprise software platforms, modern web applications, and backend services. My primary stack includes TypeScript, Node.js, Angular, React, PostgreSQL, MongoDB, and REST-based microservices.

I specialize in platform architecture, frontend ecosystems, API design, developer tooling, and scalable workflow automation. At Dell Technologies, I built and evolved the Developer Portal, reusable component packages, API validation services, PDF export services, real-time experiences, and micro-frontend foundations used by multiple teams.

I have hands-on experience designing reliable backend systems with Node.js, Express, LoopBack, Prisma, ASP.NET Core Web API, PostgreSQL, MongoDB, WebSockets, JWT, and OIDC/SSO. I focus on maintainability, validation, security, performance, and production-ready delivery.

More recently, I have focused on agentic AI workflows and multi-agent orchestration. I have built AI-assisted refactoring workflows using MCP, Azure DevOps, GitHub Copilot agent mode, Claude Code, AST-based code mapping, LLM validation, and human approval gates.

I enjoy leading engineering teams, creating technical designs and estimates, mentoring developers, and establishing reusable architecture patterns. I have led teams of engineers, mentored junior developers and interns, and helped teams improve delivery speed through shared component ecosystems and engineering guidance.

I also work independently on full-stack contract products, including multi-tenant workflow systems with role-based access control, onboarding processes, approvals, notifications, document management, and production deployments.

Career history

Full-Stack Engineer Confidential Staffing Firm

I am building an employee onboarding tool end to end for a staffing firm that places employees across 12 client companies. The solution uses a React frontend and an ASP.NET Core Web API backend.

I am implementing step-by-step onboarding checklists, per-hire status tracking, role-based views and approvals for HR, managers, and new hires. The platform also includes document upload and HR review workflows.

Lead Architect and Sole Engineer CareerNirman4U

I designed and built the CareerNirman4U platform independently, including the data model, REST APIs, roles, workflows, frontend, backend, and production deployment. The production system uses Angular, PrimeNG, Node.js, Prisma, JWT, PostgreSQL, and Railway.

I implemented a shared multi-tenant platform with Student, Trainer, Channel Partner, Admin, and Super Admin roles. Features include resume uploads, invite-code registration, requisition and hiring workflows, approval flows, notifications, transaction exports, scoped access control, and instant email alerts for destructive actions.

Software Architect o9 Solutions

I led frontend development for the Assortment Planning module in Kibo, o9's enterprise planning platform. I led a six-engineer team, owned design documents and estimates, and guided React component development for the Arvo token-based design system.

I built a multi-agent refactoring workflow using GitHub Copilot agent mode, Azure DevOps MCP, Claude Code, AST-based architecture mapping, human approval gates, and automated testing. The workflow reduced SonarQube issues from more than 80 to 4 with zero regressions, was rolled out to about 40 developers, and improved Vitest line coverage from 73% to 95%.

I also owned an asynchronous Node.js PDF generation service that rendered large server-side data grids into PDF exports up to approximately 45 MB, with completion notifications delivered to the UI.

Senior Principal Software Engineer Dell Technologies

I advanced Dell's Developer Portal into a reusable ecosystem of approximately 60 Angular and vanilla JavaScript NPM packages adopted by six to seven teams. I mentored four junior developers, an intern, and engineers from other teams, helping reduce development time by 30% and improve feature delivery speed by up to 25%.

I built and owned a production Node.js service for exporting API documentation as PDFs. I also co-designed a React and Next.js micro-frontend for documentation retrieval and rendering, reducing bundle size by 40%, increasing Lighthouse scores from 65 to 85, improving SEO from 42 to 75, and increasing API onboardings by 25%.

I delivered a Gemini-powered OpenAPI specification generator backed by a Node.js validate-and-retry service using OpenAPI 3.0 and Spectral rules. I also built a real-time portal chatbot UI that streamed LLM-backed answers and ticket creation over WebSockets.

Principal Software Engineer Dell Technologies

I built the Dell Developer Portal from scratch using a micro-frontend architecture that later became a reusable foundation for other teams. I also helped implement Adobe Analytics centrally in the micro-frontend shell, enabling consistent tracking across loaded applications and key business workflows.

I built the production Node.js API Lint service required for API publishing at Dell. The service accepted JSON and Markdown API specifications, converted Markdown to JSON, validated OpenAPI 2.x and 3.0 definitions using Stoplight Spectral, and returned formatted validation results.

I designed the validation service to execute each validation in a self-terminating child process, keeping requests non-blocking and preventing orphaned processes. I also created independent GitLab CI/CD pipelines for micro-frontends on Pivotal Cloud Foundry, using HashiCorp Vault for secrets, and integrated OIDC-based SSO.

Software Senior Engineer Dell Technologies

I built a new Angular 8 version of VAST-P, a factory automation tool used by Dell's Cork, Ireland factory. The application included an interactive server topology view for identifying healthy and failing ports.

I developed Node.js and LoopBack REST APIs backed by PostgreSQL, processed topology data, and streamed live server logs to the UI over WebSockets. I also designed a sequential orchestration solution using Web Workers to run workflows per server or in batches without freezing the UI.

This workflow orchestration solution received Dell's global Most Innovative Idea award.

Senior Software Developer Sapiens Technologies

I worked on migrating LifeSuite, an international life insurance policy platform, from Adobe Flex to Angular.

I also mentored a team member during the migration and contributed to the modernization of the frontend application.

Front End Developer Harman Connected Services

I rebuilt a legacy desktop application as an Angular web application for Toyota Telematics Cloud.

I completed the web application rebuild in five months and received two Extra Mile Awards for my contributions.

Freelance Web & Graphic Designer Self-employed

I worked independently as a freelance web and graphic designer.

I delivered web and visual design services for client projects.
