• Built a robust eVoting platform using React + Node.js, handling large-scale, real-time participation while reducing operational costs and human error.
• Integrated Stripe billing systems, optimized API performance, and managed backend services for e-commerce applications using modern DevOps workflows.
• Mentored junior developers, led code reviews, and established best practices in CI/CD.

Voice-Enabled RAG Assistant (Talking Avatar)

• Built pipeline: JSON Q&A → embeddings → ChromaDB; exposed via Flask /ask API.
• Implemented RetrievalQA with OpenAI (LLM + embeddings); tuned retriever (k=4) for grounded, low-latency answers. Integrated ElevenLabs TTS (voice ID via env), returning base64 MP3 with robust error handling/fallbacks.
• Shipped React (Vite) chat UI with animated “speaking” avatar; reliable data-URI audio playback and autoplay-safe behavior.Resolved CORS/media quirks (flask-cors, safe encoding); added env-driven config, Postman tests, and setup docs. Designed as a drop-in service for e-commerce/telehealth/support portals to boost accessibility, engagement, and self-serve help.

• Guided and mentored a team of software engineers working with React, TypeScript, and Node.js, fostering a collaborative, innovative, and high-performance development culture.
• Developed and launched an AI Response Evaluator App that automated evaluation processes—enhancing assessment accuracy and drastically improving feedback response time across internal tools.
• Engineered a Code Review Automation Tool tailored to developer workflows, enabling insightful peer reviews, improved code quality, and faster iteration cycles.
• Built an NLP module using the Natural library (Node.js), improving the company’s real-time text analysis capabilities for internal AI-powered tooling.
• Led the Model Evaluation Initiative, designing robust testing, validation, and reporting mechanisms to ensure production models met quality and performance benchmarks.
• Oversaw the full lifecycle of an HRIS (Human Resource Information System), implementing time-sensitive features using MySQL, Sequelize, and Cron jobs, ensuring timely delivery and system stability.
• Developed and aligned technical strategies with company goals by staying on top of emerging technologies (e.g., AI toolkits, CI/CD best practices, developer productivity tooling).
• Conducted regular code reviews and enforced modern coding standards and documentation practices to ensure long-term maintainability, scalability, and performance of applications.
• Collaborated with cross-functional teams using tools like Slack, Trello, and Git, actively translating product requirements into functional and scalable technical implementations.
• Actively contributed to backend development while leading engineering strategy, sprint planning, and innovation efforts across product verticals.
