Solutions beyond Syntax

About Me

Jasen Garcia portrait

Hello & Welcome!

I'm Jasen Garcia, a Software Engineer who turns requirements into reliable results across mobile, web, and backend. I focus on clean design, secure data flows, and scalable cloud services—shipping solutions that work.

Feel free to reach me through social media or send me an E-Mail.

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 Full-Stack Software Engineer / Architect · 2023 – Present · Tinley Park, IL

  • Architected & shipped PyroPunch – a greenfield workforce & safety platform for pyrotechnic crews (Flutter/Dart mobile app + internal web dashboards, Azure Functions, Cosmos DB), owning system design from initial diagrams and data models through production rollout.
  • Defined service boundaries, API contracts, and schemas for scheduling, shows, time punches, and crew management; automated 90%+ of manual scheduling steps and cut manager data entry from ~4 hr/week to < 25 min/week.
  • Led an engineering team and established Agile SDLC practices (backlog grooming, sprints, code reviews, CI/CD), turning ambiguous owner requests into prioritized work and shippable increments.
  • Extended the platform with geofenced punch-in/out, device fingerprinting, and audit logging, delivering ~98% location-accurate timecards and reducing payroll corrections by ~80%.
  • Implemented RBAC, MFA, and OWASP-aligned input validation; blocked 100% of SQLi/XSS test payloads in UAT and hardened internet-facing APIs.
  • Built GitHub Actions CI/CD pipelines (build, test, quality gates) that keep average bug-fix turnaround under 30 minutes and make shipping new app versions routine.
  • Embedded PGI, NFPA, APA, and State Fire Marshal guidance into in-app workflows and checklists, helping maintain a zero-incident safety record across indoor and outdoor pyrotechnic and special effects shows.

Five Alarm Fireworks

Manager / Pyrotechnics Operator · 2016 – 2023 · Tinley Park, IL

  • Managed 140+ computer-fired displays (stadiums, festivals, sports) with 0 safety incidents over 7 seasons.
  • Introduced digital checklists & teardown SOPs — average setup/cleanup time improved ~30%, reducing crew overtime and misfires due to missed steps.
  • Piloted early PyroPunch prototypes (CSV export → cloud) and eliminated paper timesheets, recovering 100+ admin hours/year.
  • Hired & trained 30+ technicians; retention increased ~20% through clear expectations, safety coaching, and on-the-job mentorship.
  • Coordinated HAZMAT logistics for 1.3G/1.4G materials across multiple states while maintaining 100% DOT compliance.
