Featured Projects
High-performance applications driving real-world business impact
ijewel Design
A 3D jewelry showcase platform where users explore and personalize designs in real time. Optimized for performance by removing redundant API calls, reducing backend load, and improving embed load speed by 25%. Resource optimization led to faster page rendering and a smoother, more engaging experience.
Large API payloads and redundant network requests degraded embed performance and increased backend load.
Removed redundant API calls, introduced caching strategies, and optimized frontend rendering patterns in Next.js.
Reduced embed load time by 25% and improved user interaction speed significantly.
ijewel Editor
A modern 3D jewelry editor for creating, visualizing, and sharing models interactively. Introduced real-time previews and embedding similar to YouTube, cutting design iteration time by 40% and enhancing collaboration.
Design iteration and sharing processes were slow due to the lack of real-time collaborative visualization tools.
Introduced real-time previews and embedding capabilities similar to YouTube using React and WebGi SDK.
Cut design iteration time by 40% and significantly enhanced cross-functional collaboration.
Urbantasker
A home-service platform where users post jobs and receive bids from verified providers. Built an engaging UI for posting and bidding, added email and digest notifications for quick responses, and optimized React + GraphQL flow for smoother interactions and faster performance.
Poor user engagement during posting and bidding workflows, combined with inefficient data fetching degrading UI performance.
Built an engaging UI for posting and bidding, added email and digest notifications, and optimized React + GraphQL flow.
Achieved smoother interactions, faster performance, and increased user response rates.

Engineering Principles
How I approach building scalable and reliable systems.
Scalability First
Design systems for horizontal growth and maintainability from day one.
Security by Design
Build secure APIs and backend services with OWASP best practices baked in.
Production Performance
Prioritize performance and reliability in every deployment decision.
Clean & Modular Code
Write testable, self-documenting, and reusable modules across the stack.
User-Centric UI
Frontend performance is user experience — every millisecond matters.
About Me
Full Stack Developer with 4+ years of experience building modern, high-performance web applications. I specialize in transforming ideas into reliable, user-focused digital products.
My journey started early, exploring the fundamentals of programming and developing a strong curiosity for how things work. Over time, that curiosity grew into a disciplined approach to solving problems through clean, thoughtful engineering.
With a BSc in Computer Science and hands-on experience across both frontend and backend systems, I’ve contributed to scalable architectures, intuitive interfaces, and robust application logic for products used in real-world environments.
Today, I focus on creating software that is efficient, maintainable, and purposeful—whether it’s crafting responsive UI experiences or architecting backend systems designed for long-term growth.
