Zachary Fried

Software Engineering Intern

C# · .NET · Python · SQL · JavaScript · Knockout.js · Azure DevOps

• Implemented the C#/.NET server-side UDP request/response path for vehicle-position lookups, including object serialization; verified the complete flow with the Android client on physical hardware.
• Cached vehicle positions by site ID in a concurrent dictionary, refreshing from the database after three minutes.
• Designed and built a reproducible Python evaluation harness comparing six hosted and self-hosted LLMs across 159 cases, grading tool calls against ground-truth application state rather than model replies.
• Added a tracking toggle and persisted vehicle-limit settings across site-level and global databases.
• Built and browser-tested a C#/SQL/JavaScript configuration application for salespeople using Knockout.js that maps user selections to required components, designed to replace manual PDF cross-referencing.
• Contributed to relational schema design with engineering mentors; proposed changes adopted into the final design.

Linux Administrator & Data Processor (Contractor)

Linux · Bash · Python · MySQL · Docker

• Sole Linux administrator for shared research-lab servers, concurrent with a full UMD course load.
• Diagnosed recurring server crashes with custom log-capture utilities, later deployed as Nagios plugins; traced failures to a GPU-designed ML tool running CPU-only and resolved them with CUDA configuration and resource limits.
• Automated backups, file-integrity monitoring, and data processing with Bash, Python, and MySQL scripts.
• Deployed Docker applications and authentication services; authored guides used by multiple research labs.

Postbaccalaureate Research Fellow

Python · MySQL · OpenAI API · data pipelines

• Built Python workflows to normalize, tokenize, and extract dictionaries from large-scale Reddit datasets.
• Optimized scripts transforming smartphone sensor data for a digital-biomarker analysis platform.
