Founder & Lead Developer at Tickr Timeclock (2026-03 – Present)

Build and operate a multi-tenant SaaS time clock for dental and healthcare practices.

• Build and operate a multi-tenant SaaS time clock: for dental and healthcare practices. Kiosk clock-in, payroll verification, sick-day accrual and BC Employment Standards Act calculations.
• Retrofitted single-database multi-tenancy onto a live payroll database: tenant-scoped 15 tables and rebuilt eight uniqueness constraints as composites.
• Designed the authentication stack by hand: cache-backed bearer tokens with a token-version column that invalidates every session on password change, plus kiosk auth using per-location tokens, station PINs and single-use punch tokens.
• Diagnosed a production outage that was not in the code: the web SAPI had silently drifted to a different PHP build with mbstring disabled while CLI PHP was untouched; isolated it by probing runtime and extension state against the CLI binary.
• Designed the per-employee billing metric: distinct employees who punched in the period, with a high-water mark that never falls so a staffing spike cannot produce a surprise invoice.
• Built the admin and kiosk interface framework-free: vanilla JavaScript on Blade shells, and integrated Stripe Checkout, Billing Portal and signature-verified webhooks.
• Operate the deployment: SSH Git deploys, scheduled commands for forgotten-clock-out alerts and photo retention, per-tenant email and SMS, and punch photos served only through six-hour signed URLs.

Software Developer (Co-op) at Project Equifood (2022-09 – 2023-03)

• Built the REST API in Node.js and Express.js serving inventory, donation and user-account data to a React single-page client for a food-redistribution platform.
• Designed the MariaDB schema and wrote the SQL behind inventory tracking and user management.
• Owned the design documentation: authored the UML diagrams for a cross-functional team, then planned and drove the sprints against them.

Contractor Sales Associate at Sorrento Building Centre (2016-07 – Present)

Nine years' continuous employment, held throughout a full-time Computer Science degree and while building Tickr.

• Resolve live mainframe and point-of-sale failures under customer pressure, restoring service fast enough to keep the store open.
• Technical point of contact for large contractors, scoping materials lists and quotes for high-value builds.
