Jason Harab

Engineering Leader Product Builder AI-Driven Systems

I build and scale real-world software products — from zero to production, and from prototype to platform. I apply modern technologies, including AI, to solve real business problems and create measurable impact.

Featured Work

Products in production

Real systems serving real users — built with modern, serverless-first architectures and the same engineering rigor I bring to every team I lead.

Scheduling • RSVP • Availability SaaS

A scheduling and RSVP platform for recurring events, built on a fully serverless AWS backbone for low cost and effortless scale.

  • Recurring events with smart availability windows
  • Automated reminders and RSVP notifications via SES
  • Event-driven architecture using EventBridge
  • Zero idle cost — scales to zero between events

My League Hero
Sports League Management Platform

A multi-tenant SaaS for running hockey (and other) leagues end-to-end — registration, scheduling, payments, stats, and notifications across complex role hierarchies. Built by someone who has actually run leagues, not just shipped software for them.

  • Multi-tenant org / league / division / team / player model
  • Schedule generation with rink, ref, and scorekeeper constraints
  • Live scorekeeping, penalties, and stat tracking
  • Registration, payments, and roster management in one flow
  • Role-based access for admins, captains, refs, scorekeepers, players

Built by an insider

I'm not just the engineer — I'm the user. 15+ years in and around hockey.

  • 15 years officiating as a referee
  • Years as a league administrator running real seasons
  • Long-time scorekeeper — every edge case, I've lived it
  • Captained teams across multiple leagues and levels

SkatingReport
Learn to Skate Skill Evaluation Platform

A digital evaluation platform for learn-to-skate programs that replaces paper skill sheets with real-time progress tracking, branded reports, and program-wide visibility.

  • Digital skill tracking from any device during on-ice evaluations
  • Automated progress reports shared directly with skaters and families
  • Roster, class, level, and instructor management in one system
  • Program-wide visibility into attendance, progress, and instructor activity

Sons of Ruthie Scorekeeper
Hockey Scorekeeping System

A hockey scorekeeping site originally built in 2009 that has remained in active use ever since, hosted on my own personal server and maintained for real-world league operations.

  • Game-day scorekeeping workflows designed around live league operations
  • Long-running production support for a system in continuous use since 2009
  • Self-hosted deployment and maintenance on personal infrastructure
  • Purpose-built tooling shaped by years of direct scorekeeping experience

Building with AI in production

I’ve been at the forefront of applying AI in real-world systems — not as experiments, but as production features that drive measurable outcomes.

How I Build

Breadth that creates leverage

I’ve worked across a wide range of technologies — traditional full-stack systems through modern cloud-native architectures. That breadth lets me adapt quickly, evaluate new tools honestly, and apply the right solution without being locked into a single stack.

I intentionally work slightly outside my comfort zone — that’s where the best systems are built and where new technologies create real impact.

01

Scalable by design

Architectures that grow with the product, not around it.

02

Observable and data-driven

Instrumentation, metrics, and feedback loops as first-class citizens.

03

Pragmatic, not over-engineered

Choose the simplest thing that holds up under real production load.

04

Focused on real outcomes

Ship what moves the business — measurable impact over activity.

Foundation

Infrastructure, security, and compliance

I started my career in the cleared DoD space, where I developed a deep foundation in DevOps, networking, and security. These environments required systems to be resilient, secure, and tightly controlled — shaping how I approach engineering from the ground up.

I’ve carried that foundation into modern product environments, including SOC 2-aligned systems, ensuring scalability, observability, and access control are built in from the start.

Today, I combine that high-trust engineering foundation with modern SaaS architectures and AI-driven systems — enabling rapid development without sacrificing reliability or security.
