Gobind Singh — Full Stack Developer specializing in React, Next.js, TypeScript, and Node.js. Building software is easy. Keeping it reliable as complexity grows is where the work begins.
I'm a full-stack developer specializing in React, Next.js, TypeScript, and Node.js. I build, rebuild, and integrate production web apps for startups and enterprises — from micro-frontend architectures to AI-driven platforms — with a focus on performance, clean architecture, and shipping systems that hold up in production.

02 // Track Record
Where I've worked, and what I shipped there.
- Worked as a full-stack engineer on an AI-driven conversion rate optimization platform, building and scaling personalized web experiences using React, Node.js, and modern frontend caching and data-fetching strategies.
- Re-architected the monorepo by separating applications, shared UI components, and data layers, enabling independent deployments and improving build performance by approximately 15-20%.
- Designed and implemented backend APIs and core database workflows using NestJS, Express, and Prisma, supporting high-impact product features and internal service integrations.
- Improved frontend performance, reliability, and routing stability through optimized rendering patterns, client-side caching, and migrating from Next.js App Router to Pages Router for improved ecosystem compatibility.
- Led frontend development for large-scale internal healthcare and insurance portals, enabling hospital-side workflows such as agent-assisted discharge and claims processing.
- Owned and delivered a production-grade portal end-to-end, including frontend architecture, state management, and close collaboration with backend, DevOps, QA, and product stakeholders.
- Unified multiple frontend codebases into a single Nx-powered monorepo, reducing code duplication by approximately 20% and improving developer productivity through optimized tooling, HMR, and linting workflows.
- Migrated a monolithic frontend application to a micro-frontend architecture, improving scalability and release velocity while reducing JavaScript bundle size by roughly 45% using code splitting, lazy loading, and tree shaking.
- Designed and developed a responsive marketing website to establish the company's online presence and showcase its car rental services.
- Built a static, high-performance website using Next.js and Lottie animations, focusing on fast load times and clean visual presentation.
- Developed modern, performant, and maintainable frontend code for multiple client-facing and internal web applications.
- Collaborated closely with designers and management to implement UI requirements, document features, and support end-to-end project delivery.
03 // Engineering Manifesto
// Performance
Latency is a bug.Optimizing for the edge is a requirement, not a luxury.
// Reliability
Boring Tech.Prioritize stable infrastructure for core systems.
// Culture
Read > Write.Clean code reduces cognitive load for the next engineer.
// Deletion
Remove Code.If it doesn't serve a purpose, it shouldn't exist.
// Context
No Black Boxes.Systems must be observable to be production-ready.

CleanTank Services
I built a multi-page Next.js site for an industrial water-tank cleaning company serving hospitals, government bodies, and franchise partners across India. Service quotes and franchise applications run through separate lead funnels, and the content is pulled from Contentful so the team can update copy and photos without a deploy.

Creation Hub
putting an AI assistant inside the product, not next to it
I architected and shipped Creation Hub, the workspace where our customers plan marketing experiments by talking to an AI assistant. Instead of a chat window that only gives advice, I built one where the AI's answers arrive as working parts of the app — so a user can ask a question, see the numbers, think out loud, and act on the answer without ever leaving the conversation.

07 // Endorsements
What people I've worked with have to say.
"Gobind was enthusiastic from the get go and he took up the project as expected and defined the scope and made sure I felt comfortable with him taking lead. He even brought in his team members to help brainstorm the requirements and understand the whole idea for developing a website. Will definitely recommend Gobind for his technical abilities at your company."
Badri Narayan Mohan • Founder • TakeMyCar
"I worked closely with Gobind at Optimeleon and reviewed a lot of his code. What stands out most is how much thought he puts into designing systems before writing code — he thinks through how things will scale and adapt as requirements and teams change, so the solutions he builds tend to last instead of needing a rewrite months later. His coding standards are among the best I've seen, and he fixes problems because they should be fixed, not because someone asked or there's recognition attached."
