• Integrated ThreadX (a subset of Microsoft Azure RTOS + NetX) into existing code, fortifying real-time

responsiveness and hitting a 99.99% uptime threshold

• Overhauled core Python algorithms in ThreadX (a subset of Microsoft Azure RTOS and re-coded them in C, minimizing CPU load and boosting throughput by 21%

• Refactored entire Python object hierarchy to robust C-based structures, achieving a 89% reduction of

fragmentation, 33% reduction of RAM allocation, and increasing the largest free chunk by 79%

• Pruned and quantized the onboard neural-network dataset from 16 MB down to 5.5 MB (66% reduction), enabling real-time inference on constrained hardware

• Migrated large static allocations from the .bss segment into heap-managed buffers, delivering an 8× reduction in static memory usage, eliminating long-term fragmentation, and sustaining sub-5 ms allocation latencies

Designed and built a modern web application with APIs that generate quotes to enable users to easily access to motivational speeches.

• Designed and coded the 1-1 private chat feature with React as the front-end and Firestore (of the Firebase) as the serverless backend to maintain the data of chats

• Collaborated with a team of engineers tackling challenges ranging from prototyping system design and implementing the project via pair programming, and group programming with Agile stand-up, which resulted in meeting the client’s business requirements by the deadline

• Defined and handled the user interaction of the chatting feature with vanilla CSS

• Created Terraform service with Docker integration to automate Node.js server initialization for easily launching AWS EC2 Instances to reduce the deployment time from 30 minutes to 2 minutes

• Replaced legacy APIs and redirected database to a new one that was optimized to handle 3,000 requests per second, a 500% throughput increase, with Express Router and PostgresSQL

• Decrease stress testing cycle length by identifying and revising system bottlenecks using Loader.io

• Reduced the code size to 0.25x and increased readability by converting class components to Hooks with React

• Met the client’s business requirement regarding the filtering question-and-answer feature by utilizing Regex

• Used Git and Trello to facilitate Agile development by using conduct code reviews with team members

Collaborated in designing, developing, and debugging a dynamic and responsive web application, including vanilla CSS and Javascript components, managing React hooks and Axios-driven API calls.
