[ Software Engineer · Backend & Data · Aiming at Fintech ]

I build software that's correct, maintainable, and well-architected. Not just software that runs. Recent grad from Seneca Polytechnic, currently learning AI/ML, and shipping end-to-end projects on my own time.

01 About

Most software works until it doesn't. I build for the part where it has to keep working. Clean architecture, airtight data, and code that doesn't make the next developer miserable.

I'm a software developer who cares about building things that are correct, maintainable, and well-architected, not just things that run. I completed my Computer Programming diploma at Seneca Polytechnic in April 2025, and alongside the coursework I've spent a lot of time teaching myself: how systems are designed, why certain patterns hold up under pressure, and how to write code other people can actually build on.

My core stack is Python, Java, C#/.NET, and SQL on the backend with React and Node on the front, plus a working foundation in data engineering, ML, and software design & architecture. I'm most drawn to backend and data-heavy problems: work where correctness, structure, and clean design genuinely matter, which is a big part of why I'm aiming at fintech.

  • Checking & savings accounts with freeze / unfreeze controls
  • Auto-flagging of transactions over $10,000 as potential fraud
  • Monthly category analytics + paginated transaction history
  • Real-time in-app notifications on every transaction event
  • Swagger / OpenAPI docs + xUnit + Moq coverage on core logic

CURRENTLY

Studying AI/ML. Looking for a fintech team that cares about craft.

I just shipped an end-to-end churn prediction pipeline (Logistic Regression, Random Forest, XGBoost) and I'm continuing to deepen my foundation in classical ML, evaluation, and experimentation. Looking for software engineering roles on teams where correctness, code quality, and architecture are taken seriously.
