About Me

I specialize in modern JavaScript (ES6+), React.js, and Node.js with a strong focus on building REST/GraphQL APIs, state management, cloud deployment and performance optimization.

I have worked on projects from telemedicine platforms to KYC verification systems and real-time location tracking, focusing on secure, responsive, and user-friendly solutions.

My experience includes integrating RESTful APIs; implementing authentication and authorization; designing reusable UI components and relational schemas; and deploying to cloud platforms while applying system design concepts to build scalable architectures—all while delivering quality code in Agile environments.

What I've done so far

Work Experience

AI Interface Engineer

Charles schwab

March 2025 - May 2025

Engineered an interactive React with TypeScript & TailwindCSS interface for AI-powered KYC verification, integrating OpenAI API with CrewAI and Hugging Face models for multimodal identity recognition and semantic similarity validation. Architected real-time facial guidance overlays for liveness detection (head turns, blinks) using synchronized vision inference streams, achieving a 35 % reduction in manual verification latency

Designed and deployed a multi-layer liveness detection pipeline that seamlessly connects React-based vision modules to Python + FastAPI inference endpoints. Integrated Kafka for event-driven message brokering, Redis caching for low-latency identity checks, and WebSocket channels for real-time user feedback and fraud-detection loops—enabling millisecond-level synchronization between front-end motion tracking and back-end model validation.

Developer Group Member

Google Developer Groups (GDG) on Campus — Long Island University

May 2024 – Jan 2025

Collaborated with cross-functional teams to organize and lead AI, cloud, and web development workshops, emphasizing practical applications of Google technologies.

Contributed to a group project, InternEase, by developing the front-end interface using React.js and implementing responsive design systems to enhance usability and scalability

Engineered front-end prototypes integrating Google APIs such as Maps, Authentication, and Cloud Functions, demonstrating secure and real-time data workflows.

Designed and implemented an AI-driven customer service chatbot by integrating GPT-3 with a Retrieval-Augmented Generation (RAG) pipeline, enabling context-aware and document-grounded responses for a web-based application.
