• At Twine, I led the development of an open-source service that provides highly scalable and reliable real-time communication capabilities to web applications with built-in connection state recovery.
• Architected a drop-in auto-scaling WebSocket infrastructure using AWS (EC2, DynamoDB, Elasticache for Redis, Elastic Beanstalk) to provide web applications with real-time data exchange.
• Engineered RESTful API backend in JavaScript, TypeScript, Node.js, and Express to facilitate communication with the Twine Server and persist received data in DynamoDB and Redis.Constructed a decoupled Redis and AWS.
• Implemented automatic connection state recovery mechanisms using JavaScript and TypeScript to provide in-order delivery of missed data and mitigate client disruption in case of a dropped WebSocket connection.
• Developed cron job logic to automate removing stale data from Redis every 2 minutes to clean out Redis cache and optimize cloud computing costs.
• Containerized server code in Docker for ease of deployment within an AWS Elastic Beanstalk environment and to improve the maintainability of the Twine server code.

• At Launch School, an online platform renowned for its rigorous and mastery-based software engineering curriculum, I played a pivotal role in shaping the future of aspiring developers. My contributions included:
• Conducted ~200 live coding interviews testing student’s understanding of JavaScript, Ruby, and SQL, offering actionable feedback to enhance students' coding and interview skills.
• Graded 120+ written assessments, critically evaluating students' grasp of programming fundamentals, such as language syntax, variable scope, memory allocation, relational database design, networking, HTTP, and OOP.
• Facilitated over 50 code reviews on student projects, focusing on bug resolution, syntax accuracy, knowledge of programming fundamentals, OOP concepts and design in Ruby, and relational database knowledge.My time at.

• Designed, developed, and deployed bespoke Rails and React applications for a versatile development shop. Catered to a diverse clientele, including:
• Small and medium-sized businesses
• Non-profit organizations
• Governmental contractsDelivered customized solutions that aligned with their specific needs and objectives.

• Alongside my professional work, I contribute to the open-source community by developing and sharing innovative projects that foster collaboration and drive technological advancement. Notable achievements include:
• A reimagining of the classic game Snake, starring a brain-eating Snake Plissken (TypeScript, React).
• A real-time webhook monitoring tool (DigitalOcean Droplet, Express, MongoDB, Nginx, Node.js, PM2, PostgreSQL, React).
• Developed a voter data management web application with Ruby on Rails, Postgres, and React, which enabled efficient uploading, sorting, and searching of registered voter data, enabling validation of voter registration.
• Built a community-driven message board for plant enthusiasts (Sinatra, PostgreSQL, HTML, and CSS).
