Full Stack Software Engineer with 3+ years of experience designing and shipping scalable, production-ready web applications used by thousands of active users. My core stack is React (v16–18), Next.js, Vue.js (2 & 3), Node.js, and TypeScript — and I'm equally comfortable architecting the frontend as I am designing the APIs and databases behind it. On the React and Next.js side, I've built complex, performance-optimized interfaces with Redux Toolkit for state management, implemented server-side rendering and static generation with Next.js to improve Core Web Vitals and SEO, and developed reusable component libraries adopted across multiple teams. I've worked on everything from AI-powered real-time page editors to healthcare clinical dashboards to large-scale e-commerce and B2B platforms. On the backend, I design RESTful APIs and Backend-for-Frontend (BFF) layers using Node.js and Express, with PostgreSQL, Prisma, Sequelize, and Supabase on the data side. I've also built with Python FastAPI where the project called for it. Beyond coding, I take testing seriously — maintaining 75%+ unit test coverage with Jest and Enzyme, and building end-to-end test suites with Playwright that cover critical user workflows. I integrate quality gates into CI/CD pipelines, lead code reviews, and mentor junior engineers. I've worked in fast-paced Agile environments my entire career, consistently delivering within sprint cycles and owning features from planning through production. Currently a Senior Software Engineer at TechClan, leading enterprise platform development and driving architectural decisions.

Employment History

Senior Frontend Software Engineer at TechClan Current 2025 - Now
At TechClan, I serve as a Senior Software Engineer with full ownership over enterprise web application development — from initial architecture and technical planning through to testing, deployment, and post-release iteration. I make core technical decisions on a platform actively used by thousands of users, balancing feature velocity with long-term code health. One of my most significant contributions has been leading the migration from Vue 2 to Vue 3 across a live production codebase, resolving compatibility challenges at every layer of the stack while ensuring zero disruption to end users throughout the transition. To strengthen release confidence, I designed and implemented a comprehensive Playwright-based end-to-end test suite covering 15 to 20 critical user workflows, which measurably shortened QA turnaround cycles and reduced production regression incidents. I also introduced code quality gates and automated coverage thresholds directly into our CI/CD pipelines, creating a consistent engineering standard across the team. Beyond my individual technical output, I actively mentor and onboard junior engineers through structured, detailed code reviews and hands-on pairing sessions — raising the overall delivery standard and helping the team grow faster.
Full Stack Engineer at CodeFinity Solutions 2024 - 2025
At CodeFinity Solutions, I led the architecture and end-to-end delivery of scalable web applications, taking ownership of the complete development lifecycle from system design and technical scoping all the way through testing, staging, and production deployment. A key focus of my work was performance — I identified and resolved API communication bottlenecks and suboptimal frontend rendering patterns that were slowing down page load times, resulting in a noticeably faster and smoother user experience across the board. I worked closely with product managers and designers to translate business requirements into clearly scoped technical solutions, consistently shipping features on time within our two-week Agile sprint commitments. I also championed the adoption of modern tooling and development practices that improved overall team velocity, reduced technical debt, and made our codebase more maintainable across multiple active projects running in parallel. One standout project was Waltz AI — an AI-powered landing page builder where I led state management architecture, integrated GrapesJS for dynamic in-browser page editing, built an interactive analytics dashboard, and connected Supabase and AWS S3 for reliable backend and asset storage.
Software Engineer at Confiz limited 2022 - 2025
At Confiz Limited, I worked as a staff augmentation engineer embedded directly within client teams, joining projects in their early stages and taking full ownership of assigned frontend modules from day one. I participated actively in all Agile ceremonies — sprint planning, backlog refinement, daily stand-ups, and retrospectives — which gave me a strong foundation in collaborative, delivery-focused engineering. Using React, Material UI, and Redux Toolkit, I built responsive and accessible frontend interfaces for enterprise-scale applications across multiple industry verticals, including healthcare, retail intelligence, real estate, and automotive. For a US-based healthcare platform, I developed clinical documentation interfaces that allowed physicians to capture voice-based notes and review AI-generated patient summaries, working closely with backend engineers to ensure security and reliability. For Walmart's Intelligence Business Growth platform, I built React-based interfaces for AI-powered forecasting tools, integrated AG Grid Enterprise for complex data rendering, developed a reusable date range picker deployed as a micro frontend, and connected everything through a Node.js Backend-for-Frontend layer. I also developed a shared component library that was adopted across multiple teams, eliminating duplicated UI work and improving development consistency. To keep quality high, I maintained 75%+ unit test coverage across core modules using Jest and Enzyme, and regularly contributed to code reviews and knowledge-sharing sessions that helped junior teammates adopt team conventions faster and grow more confidently.
