### Software Engineer @ Quentin Cloud
Jan 2020 – Jan 2021
● Architected a Serverless application with multiple Python backends utilizing AWS Chalice for API routing with AWS Lambda functions.
● Leveraged Terraform to create the infrastructure of the system programmatically to deploy and run multiple AWS cloud assets.
● Designed and implemented a MySQL database running on AWS RDS for an ACID compliant secure store for user data.

### Software Engineer @ CacheQL (Open Source)
Jan 2019 – Jan 2021 | Greater Los Angeles Area
• Led a team of engineers to build a server side caching engine library (including an optimized parser for GraphQL queries) that enables partial query and field detection through normalization of request data fields to improve response time and offload database endpoint calls.
• Implemented a server side cloud-based Redis with a time-to-live/expiration invalidation strategy as an in-memory key-value store to cache resource intensive queries, reducing bounce rate by rapidly serving requested data from a stable, optimized, and scalable cache infrastructure.
• Developed GraphQL/Express server and React single page demo application that leverages GraphQL’s dynamic fetching mechanism to evaluate request response time with CacheQL caching methods for direct endpoint requests.
• Engineered time and space-conscious parsing algorithms for deeply nested GraphQL queries in order to minimize endpoint calls by analyzing parsed arguments and fields with saved data keys within the Redis cache.
• Accelerated by OSLabs.

### Software Engineer @ Codesmith
Jan 2020 – Jan 2020 | Los Angeles, California, United States
• Engineered React/Redux and Node/Express single page application, containerized with Docker, and deployed on AWS Elastic Beanstalk.
• Created unit and integration tests with Jest for React and Redux actions minimizing technical debt and maximizing code coverage.
• Mentored a team of engineers in creating a Docker visualization tool showing network connections, ports, volumes, and individual container information by overseeing task delegation through JIRA, and leading code review sessions to ensure engineering best practices.

### Virtual Groove @ Open Source
Jan 2019 – Jan 2020
• Built a Microservice Architecture consisting of authentication that handles signup, login, and JWT validation, API request handling server, and music recommendation algorithm server.
• Engineered back-end with Node.js, defining complex API endpoint behaviours through declarative implementations of middleware chains resulting in intuitive routing and easily-maintained codebase.
• Used RabbitMQ as a message broker between components and Socket.IO to asynchronously deliver algorithmically derived songs to users.
• Engineered an API Gateway using a consolidated single layer GraphQL endpoint to route requests to various microservice components.
• Designed Redux store to reduce prop-drilling, maintain continuous centralized client state as a single source of truth and used Thunk middleware to receive updates from asynchronous file operations.

### Stock Overflow @ Open Source
Jan 2019 – Jan 2020
• Leveraged React’s virtual DOM with asynchronous Redux Thunk to build a responsive, dynamic front end UI composed of reusable components that augment high-speed single page application rendering and improved application scalability.
• Employed React Router to establish static routes and implement client-side routing that minimizes server calls, reduces latency page transitions, and decreases client-side load times with in a single page web application.
• Implemented OAuth 2.0 with Linkedin to offload authentication to reduce data redundancy and improve user experience.
• Utilized Websockets (via Socket.IO) for asynchronous real-time message communication for HTTP call and server load reduction for improved re-rendering and user experience with a responsive Material UI interface for a superior user experience. 
• Constructed custom Webpack build pipeline for improved module bundling and more performant dev server with hot reloading.

### Backend Software Engineer @ Hellen
Jan 2018 – Jan 2019
• Designed and developed an information management system that leveraged AWS cloud service technology(API Gateway, Lambda, DynamoDB, IAM, Cognito, CloudWatch) for a reliable, cost-effective, and high performance cloud computing architecture.
• Utilized Serverless Architecture using AWS Lambda with Node.js to facilitate HTTP requests being routed using AWS API Gateway.
• Employed AWS API Gateway to maintain and monitor secure AWS Lambda API functions going to and from AWS DynamoDB and leveraged built-in validation by creating models and mapping templates for each HTTP endpoint.
• Facilitated authentication and authorization through AWS Cognito as simple, secure, and highly scalable user sign-up, sign-in, and access control platform for custom permissions using roles and policies for identity pools.
• Developed a Vue.js frontend application as a lightweight, flexible framework that focuses on intuitive state management.

### Software Developer Intern @ HP
Jan 2015 – Jan 2015 | Philippines
• Designed and developed an internal web-based dashboard that retrieves and processes data and displays the data in a simplified format. Implemented the front-end and back-end of a process for the managers and clients.
