My Personal Interests

On my days off, I enjoy the following:

  • I love learning modern technologies;
  • Traveling and attending Computer Science events;
  • Putting up a professional pyrotechnics display;
  • And of course spending time with my family.

Experience

Rogue Productions LLC (formerly Five Alarm Fireworks)

Manager & Lead Software Engineer · 2023 – Present · Tinley Park, IL

  • Built & launched PyroPunch (Flutter + Azure Functions) — automated 90 % of crew-scheduling steps and cut manager data-entry time from 4 h/week to < 25 min.
  • Geofenced punch-in/out & device fingerprinting drove 98 % location-accurate timecards, slashing payroll corrections by -80 %.
  • Designed RBAC, audit logging & OWASP-aligned input-validation – blocked 100 % of test SQL-/XSS-payloads during UAT.
  • Built GitHub Actions CI pipeline to automate build, testing, and code checks, which enabled rapid issue detection and fixes in < 30 min.
  • Have on-boarded a 12-person crew in-app; onboarding time down -50 % & provides metrics.
  • Continue to lead outdoor/indoor pyrotechnics, including SFX shows with a zero-incident safety record.
