My Journey - Click on boxes for more info!

2020

Joined Tasteport + First year coding

Started position at Tasteport focusing on CX + DevOps. Also took first highschool coding course where I was introduced to Python and OOP

I mainly handled CX: B2B, B2C and Fulfillment relationships - operations calls, inventory and fulfillment audits, etc. I also conducted B2B Operations communications with Managers, Fleet, Fulfillment Staff, etc.

2021

Business Operations

Handling day to day operations.

Managed live B2B relations with million-dollar business owners and managers. Handled onboarding for inventory tools and operations fulfillment using Java-based tools at grocer client sites. Responsibilities included B2B operations communications with managers, fleet, and fulfillment staff.

2022

Started University at Wilfrid Laurier + Online Learning

Started off in Business and switched into life sciences after first year. Also continued to practice and take programming courses online through MITOpenCourseware(Comp Sci, Maths, Stats), Youtube, Coursera, and LeetCode.

Found lots of interest in the intersection of Computer Science and the Life Sciences.

2023

Getting into Data Science + ML

Started taking data science courses, deep diving documentation and working on learning through projects.

Python - Numpy, Pandas, Matplotlib, sklearn, Pytorch, Huggingface R - tidyverse - Focused on creating projects that could later be applied to either Tasteport (e.g. Chat Assistant, Grocery Classification) - or towards interests in bioinformatics (e.g. Rice Classification) and AI in Healthcare. Also started to work on cleaning, organizing and visualizing datasets in kaggle to understand how to work with real, messy data.

2024

Starting AI/ML Engineer position

1. Fine tuning models for grocery product grouping. 2. Before I started the new position, I also took DeepLearningAI courses such as intro to ML and DL. 3. Transferred to York University to study Biochemistry.

Contributed to the training and optimization of frontier model for thousands of SKUs for grocery product grouping - Saves hundreds of hours of manual grouping as we scale. Learned how to build ML algorithms and how to build neural networks from scratch + understand the mathematical concepts that enable them.

2025

NVIDIA Certification + Production Assistant

Recieved Generative AI and LLMs NVIDIA certification. At Tasteport I used this knowledge by building an AI assistant - Tia.

Focused on increasing my knowledge and application skills in AI and machine learning - This certification solidified my ML, DL, Transformers, LLMs, GenAI, and NVIDIA hardware knowledge. See more in the projects section above on Tia. Continued Biochemistry degree - finished 2nd year.

2026

Stage 2 Assistant, Projects - Invisible City, Semantic Caching

1. Continuing building out assistant infra. 2. Won school competition - Created a website which explains and visualizes hidden chemical risk in Toronto through an interactive map and easy to read visuals. 3. Also, seperately built a similarity-based caching layer.

See Invisible City in project section above and check out my repo on Github (Linked at top of screen)! Also worked on another project where I developed a semantic caching system using PyTorch and Redis to reduce LLM API costs and latency. Adding Computer Science Minor.
