My name is Sharon!

My interests lie in enhancing developer experience through AI, software engineering, programming languages, and human-computer interaction.

As a software engineer, my focus is on full-stack development, with an emphasis on backend engineering and AI-powered solutions.

• AI-Enhanced Developer Tools: Building intelligent systems that improve code completion, static analysis, and automated debugging.
• Large Language Model (LLM) Optimization: Implementing strategies such as typed holes and semantic awareness to improve efficiency.
• Backend & Infrastructure Engineering: Architecting scalable and robust services using NodeJS, Python, SQL, Docker, and AWS.
• Cloud & DevOps: Deploying AI-driven applications with CI/CD pipelines, and multi-platform Docker builds.
• Security & Compliance: Experience in cybersecurity consulting, focusing on PKI standards, compliance frameworks, and digital certificate auditing.

• Developed AI-based solutions within the Zeus framework, optimizing energy efficiency in deep learning model training.
• Implemented multi-platform Docker image builds for AMD64 & ARM64 using GitHub Actions.
• Integrated Prometheus for cloud-native monitoring.

• Developed a Python-based CPU inference server for Meta AI's Llama 3 LLM.
• Utilized quantized model weights for real-time token streaming without GPU reliance.

• Built an interactive coding platform inspired by LeetCode, featuring React frontend and Django backend.
• Integrated OpenAI's API for adaptive AI-driven feedback.

• Led development of a real-time ride-share pricing app (Uber vs. Lyft) using Flutter & Python.
• Implemented a dynamic polling mechanism for real-time price comparison.

• Led field interviews with 5 Certificate Authorities (CAs) to ensure PKI compliance.
• Assisted a government ministry in registering as a Root CA to the CCADB.
