Work & Research

Research focus: I work on improving sentence representations and self-supervised objectives for modern language models—bridging lightweight sentence encoders with LLMs such as BERT, LLaMA, and GPT-oss. My interests include contrastive learning, better negative mining, layer-wise representation analysis, and evaluation across semantic similarity, retrieval, and downstream NLP tasks.

Research Experience

University of Windsor – Research Assistant

Enhanced textual embeddings in BERT, LLaMA, and GPT-oss using contrastive‐learning objectives and custom loss functions.
Built a Transformer‐based interlinear glossing system, achieving 27–28% higher accuracy on SIGMORPHON 2023 shared‐task datasets.
Developed end‐to‐end pipelines for Question Answering and Sentiment Classification, improving QA accuracy by 15% and sentiment F1 by 10%.

Condensed Variable Semantic Representations

Constructed Variable Dependency Graphs (VDGs) from CodeSearchNet and fused VarCLR embeddings with graph features via a GCN encoder.
Employed InfoNCE contrastive loss and Deep Graph Infomax, achieving Spearman correlations of 0.47 (small split) and 0.45 (medium split) on IdBench.
Introduced a fallback projection for out‐of‐graph variables, retaining over 95% of full‐graph performance.

Hybrid Graph-Based Recommendation System

Developed a GNN + AutoEncoder movie recommender, achieving 90% rating‐prediction accuracy and an RMSE of 0.85.
Implemented adaptive thresholding based on users’ average history, boosting precision by 20% over non‐graph methods.

Work Experience & Development

Municipality of Lakeshore – Digital Cloud & Transformations Engineer Intern

Engineered and monitored secure cloud connectivity for 50+ municipal endpoints by supporting deployment and operation of the Cloudflare WARP client within a Zero Trust network architecture.
Designed and implemented advanced PowerShell-based network monitoring scripts to analyze UDP traffic (including UDP 443 / QUIC), detect NAT timeout behavior, and assess tunnel stability for remote users.
Developed diagnostic tooling to measure MTU path constraints, packet fragmentation, and transport reliability across wired and wireless networks, reducing root-cause analysis time by 30%.
Authored and maintained technical documentation in Confluence and tracked infrastructure issues and remediation tasks in Jira, contributing to standardized and auditable IT operations.

About Me

I’m George Kaceli, a software developer and researcher with a Bachelor’s degree in Computer Science from the University of Windsor, where I graduated with a 4.0 GPA. I’m the child of immigrants and proudly Albanian, and that background has strongly shaped how I approach challenges, with persistence, adaptability, and a drive to continuously improve. Moving between cultures taught me early on how to learn quickly, communicate clearly, and stay resilient in unfamiliar environments.

Professionally, I have experience across both front-end and back-end development, having worked on projects ranging from scalable web applications to data-driven systems and machine learning pipelines. Throughout my numerious internships I helped streamline workflows, optimize systems, and improve reliability through testing, automation, and thoughtful engineering decisions. I enjoy building software that is not only technically sound, but also practical and maintainable.

Outside of tech, sports have always been a big part of my life, especially soccer. I enjoy following the game, analyzing tactics, and staying active, and I find that many of the same principles apply to my professional life as well: teamwork, discipline, strategy, and constant iteration. Whether I’m debugging a complex system or working toward a long-term goal, I bring that same competitive mindset and focus.

In my spare time, I enjoy exploring new technologies, working on personal and research projects, and deepening my skills in machine learning, data science, and systems engineering. I’m motivated by hard problems and excited to continue building impactful software while growing as both an engineer and a person.
