WhatsApp translates the message to Gujarati: કેમ છો તમે?

Aruna receives the message written in Gujarati.

Aruna reads the message in Gujarati and understands it.

She replies in Gujarati: હું મજા માં છું which translates to "I’m fine."

WhatsApp translates her message to English.

Raj receives the message written in English: "I’m fine."

Designing a Real-Time Translation Feature for WhatsApp

I am a Software Developer with a strong interest in UI/UX design and creating digital products that are both functional and user-friendly. While developing applications using React, TypeScript, Node.js, Electron, and PostgreSQL, I became passionate about understanding how design impacts user experience and product success.

To strengthen my design skills, I independently learned UI/UX through YouTube tutorials, online courses, design communities, and hands-on projects. I gained knowledge in design principles, typography, color theory, wireframing, prototyping, user research, and usability best practices, while becoming proficient in Figma.

My combined expertise in software development and UI/UX allows me to bridge the gap between design and engineering. I can create intuitive interfaces while ensuring they are technically feasible, scalable, and performance-driven. Through my experience building fintech and trading applications, I have designed efficient workflows, real-time dashboards, and data-intensive user experiences that prioritize both usability and functionality.I continuously explore new technologies, design trends, and industry best practices to build impactful products.

Built high-performance interfaces for AI products using TypeScript and shared component systems, partnering closely with design and research.• Architected and developed high-performance fintech and trading applications using React, TypeScript, Node.js, and Electron, delivering seamless cross-platform desktop experiences.

• Designed intuitive, user-centric interfaces by applying UI/UX principles, creating wireframes, prototypes, and responsive designs that improved usability, accessibility, and user engagement.

• Implemented real-time trading systems using WebSockets, achieving sub-second data delivery and enabling low-latency market monitoring and order execution.

• Collaborated with stakeholders to translate business requirements into user-focused workflows, optimizing information architecture and enhancing overall user experience.

• Designed and optimized PostgreSQL database schemas for high-volume financial transactions, improving query performance, scalability, and data integrity.

• Integrated third-party APIs, market data feeds, and webhook systems to ensure reliable real-time synchronization across distributed systems.

• Built and maintained scalable microservices architectures with RESTful APIs, automated deployment pipelines, and monitoring solutions to support mission-critical trading operations.

I redesigned the Steam app to enhance user experience and improve overall usability. For the home page, I created a strong Call-to-Action (CTA) for better conversions and used a retro pixelated font to maintain the gaming platform's aesthetic. I also added a price filter chip for easy sorting, inspired by gaming UI trends. On the details page, I organized all the game information (release date, developer, tags) in a compact layout, making it easier for users to navigate. For the payments page, I introduced a card component for the selected game and integrated Google Pay for smooth transactions.

Redesigned the Steam app to improve user experience, streamline navigation, and modernize the interface with intuitive UI elements for seamless gaming access.
