Experience
Software Developer InternToronto, Canada
TangerineMay 2026 – Aug 2026
- Designed and built a shared Java Spring Boot microservice exposing encryption and decryption APIs, centralizing sensitive-data operations that QA automation workflows could call instead of implementing cryptographic logic.
- Owned the service end-to-end from API design through production deployment, defining its OpenAPI contract and configuring Kubernetes, Helm, Jenkins CI/CD, and environment-specific settings across 2 GCP environments.
- Instrumented the service with GCP Logging and automated email alerts for invalid endpoint access, surfacing 50+ previously untracked requests and giving engineering teams production visibility to investigate recurring failures.
Software Engineer InternToronto, Canada
TD BankJan 2026 – Apr 2026
- Reverse-engineered a legacy Java system, tracing architecture, infrastructure, dependencies, and database interactions to plan its Spring Boot and Angular migration, cutting analysis time 80% from 2 weeks to 2 days.
- Presented the modernization initiative at a Credit Origination town hall to a VP, managers, and cross-functional teams, translating technical findings into migration plans and risks for technical and non-technical audiences.
Software Engineer InternToronto, Canada
SertusMay 2025 – Jan 2026
- Owned an early-stage labour-relations product end-to-end as the sole engineer, translating evolving requirements into production workflows across 4 user types using React, Node.js, TypeScript, and PostgreSQL.
- Designed and shipped complaint-to-grievance workflows supporting multi-employee cases, evidence files, status transitions, and audit history as operational requirements evolved.
Projects
uoguelph.courses – Co-Founder
TypeScript, Next.js, React, PostgreSQL, PostHog
- Launched and scaled a production course-planning platform to 8,000+ users and 75,000+ page views, gaining 1,300 users within 72 hours of launch and earning coverage from GuelphToday.
- Engineered a degree-planning system for 81 majors and 1,900+ prerequisites, translating complex academic requirements into structured rules and recursively evaluating course selections to surface degree progress.
- Built automated data pipelines with Python, Go, GitHub Actions, and API routes to ingest, validate, and refresh 1,100+ scholarships and TA postings, replacing manual updates with scheduled collection.
TypeScript, Python, FastAPI, PostgreSQL, Docker, AWS S3
- Built and launched a full-stack transit platform reaching 422 users and 4,895+ page views, transforming multi-GB GTFS feeds into interactive route, stop, and schedule data through FastAPI and PostgreSQL.
- Engineered memory-efficient processing for multi-GB GTFS feeds using 20K-row PostgreSQL batches and route simplification, reducing API payloads from 54.8 MB to 2.8 MB within serverless memory constraints.
Octree – Founding Software Engineer
TypeScript, Next.js, Supabase, PostgreSQL, Stripe
- Built core product infrastructure for an AI-powered LaTeX editor serving 6–8K MAU, shipping multi-file project management, real-time updates, onboarding, search, and pagination across a fast-moving production workspace.
- Developed Supabase-backed Zotero citation workflows with reference syncing, search, autocomplete, and Monaco editor insertion, while debugging PostgreSQL failures and persistent-state issues affecting production editor workflows.
Leadership
HackCanada – VP Technology
hackcanada.org | judging | ctf
- Led 4 developers to build and operate 3 production platforms for 700+ hackers and 200+ projects: the public website, live judging system, and inaugural CTF, supporting up to 800 concurrent users during peak event traffic.
- Instrumented all 3 platforms with PostHog and Sentry, using session replays and error traces to diagnose 100+ production events, identify root causes, and ship fixes in real time while hundreds of hackers actively used the systems.
