Backend Developer at University of Western Ontario

December 1, 2023 - September 29, 2025

Integrated predictive models into backend systems for SARS-CoV-2 genome analysis (Covizu), enabling visualization via bead-plots for global research teams. Optimized a core Python function, reducing execution time by 50% and memory usage by 8%. Increased backend test coverage by 12% and implemented full coverage for multiple pipelines using Python unittest. Designed and optimized PostgreSQL tables for high-volume transactions; compared performance with MongoDB using custom matplotlib visualizations, achieving 20% faster execution with MySQL. Engineered a recursive function simulating nucleotide codon overlaps to support accurate genome modeling. Maintained backend codebases, debugged production issues, and resolved GitHub issues across applications.

Python Developer at Tata Consultancy Services

September 1, 2022 - September 29, 2025

Developed automation tools in Python to cluster and compare files by similarity score, generating actionable reports for insurance clients to optimize PDF template usage. Automated document comparison for pre-/post-migration validation, reducing production time and accelerating deployment schedules. Created a Python tool to auto-generate React/Angular web app skeletons, speeding delivery of client-facing applications. Managed and analyzed datasets with Pandas and NumPy, including statistical analysis of insurance premiums. Designed and executed SQL queries using Python-MySQL connector, efficiently handling large datasets. Built and consumed RESTful APIs for external interfaces, exchanging data in JSON format. Implemented backend features with MongoDB, Bootstrap, CSS, and JavaScript, enhancing dashboard capabilities. Leveraged Django MVC architecture to develop and maintain scalable web applications.
