Work Experience
Software Engineer Co-op
Cyberium Group
- Led the development of machine learning applications for cybersecurity use cases using machine learning algorithms, including large language models (LLMs), and achieved an average accuracy of over 85%.
- Established a proprietary data set from scratch for training and fine-tuning.
- Designed and developed the cloud architecture for end-to-end inference prototype applications.
Senior Software Engineer
Devo Technology, Inc
- Designed end-to-end customer usage tracking pipeline across three global business regions, exposing hidden metrics and insights, resulting in a 60% increase in billing efficiency and a 25% enhancement in customer satisfaction.
- Developed front-end applications upon customer requests for data visualization, data manipulation, time-series forecasting, and back-end self-servicing, serving over 150 active users and accelerating five additional customer acquisitions.
- Created back-end data agents served on Kubernetes for third-party data services, processing more than 10 gigabytes daily for 30 corporate clients, increasing the platform's revenue by 2%.
- Built back-end scheduling and monitoring scripts for AWS cloud and Kubernetes systems, CI/CD pipelines, unit tests, and reporting services, improving cloud systems' visibility, robustness, and availability.
- Performed ad hoc system performance analysis, root cause analysis (RCA), and business analysis using SQL, Spark, and CloudWatch logs.
Graduate Research Assistant
Northwestern University
- Created large-scale physics simulations using Linux, Bash, and high-performance computing (HPC), resulting in five publication collaborations, one conference talk, and a 6-chapter thesis.
- Wrote 2,000 lines of generation and analysis code in Python, Bash, and C++, analyzing over 500 gigabytes of simulation data and generating over 20 simulated systems while mentoring five students in programming.
- Collaborated with experimentalists. Explained, reported, and responded to questions from multiple perspectives.
