Portfolio
CITYROW
CITYROW - Fractional CTO Leadership
As Fractional CTO, I joined CITYROW during a critical growth phase following their Series A funding. The company had successfully evolved from a boutique fitness studio into a venture-backed digital fitness platform, requiring strategic technical leadership to scale their technology infrastructure and product offerings. My role was instrumental in optimizing their digital platform, which combined premium WaterRower hardware with innovative software solutions, ultimately contributing to their successful acquisition by WaterRower in January 2024.
Peer Feedback
Peer Feedback - Founder & Technical Leadership
As Founder of Peer Feedback since December 2015, I’ve led the development and growth of an innovative EdTech SaaS platform that transforms online education through technology. The platform addresses the unique challenges of managing large-scale online courses while enhancing the learning experience through AI-powered feedback systems.
The platform combines advanced AI algorithms for feedback evaluation, seamless LMS integration capabilities, scalable architecture supporting thousands of concurrent users, and research-backed collaborative learning tools.
Caproni
Caproni - Founder & Exit Success
As Founder of Caproni from March 2020 to October 2024, I built and successfully sold a podcast publishing SaaS platform. The journey from initial concept to successful exit showcased my ability to lead technical innovation while building a sustainable and valuable business.
Listen Network
Listen Network - Fractional CTO Leadership

As Software Development Contractor & Technical Advisor at GyftGram from September to December 2023, I played a crucial role in developing their contactless digital gift card platform. Working with this Techstars ‘24 company, I helped implement cutting-edge payment solutions and establish their technical foundation.
CCA
CCA Inc. - Fractional CTO Leadership
CCA Inc. administers employee benefits programs globally through their BeWell and EAP product lines. As Fractional CTO, I architected and built the technical infrastructure behind two major internal systems, replacing manual processes with automated, scalable platforms.
GeoAccess Network Analyzer
CCA’s healthcare network accessibility tool lived as a 5,000-line Google Apps Script. It calculated distances between employee populations and healthcare providers across the country, applied complex filtering criteria, and generated compliance reports. It worked, but it was slow, untyped, and impossible to test.
I rebuilt it from scratch as a cloud-native platform on GCP: TypeScript backend on Cloud Run, React frontend with shadcn-ui, and BigQuery handling the heavy distance calculations through a pre-computed view pipeline. The migration maintained 100% calculation parity with the legacy system (down to a 0.01-mile tolerance) while cutting analysis time by 30%. A dataset of 5,000+ ZIP codes that used to take minutes now processes in about 30 seconds.
The system handles multi-segment provider filtering across license types, age groups, visit modalities, and area classifications. It generates Google Sheets reports with population-weighted coverage statistics, accessibility summaries, and bar charts, then automatically shares them with the right people.
Notion Assets Pipeline
CCA needed to organize thousands of multilingual PDF assets (benefits guides, FAQs, wallet cards, orientation materials) in a centralized Notion database. The problem wasn’t just volume. Critical metadata like target country and client name was buried inside each PDF, not in the filenames.
I architected the data model and ingestion strategy, then built a Python pipeline that discovers PDFs from mixed sources (directories and ZIP archives), extracts metadata using pdfplumber and regex pattern matching, creates and links client records in Notion, and handles the uploads with duplicate detection and conflict resolution. A single client project could mean processing thousands of PDFs across 30+ languages and 50+ countries in minutes instead of weeks of manual entry.
The tool supports dry-run and validation modes so operators can preview exactly what will happen before touching the database, and it handles Notion’s API rate limits with exponential backoff.
Wall of Love
I worked with Gabriel several times over the past five years and cannot recommend him enough. So much so that I've hired him multiple times to lead and develop. He's smart, trustworthy and a great partner in thinking creatively not just about technology solutions - but how they match to business decisions.

I met Gabriel over a year ago as just another 'Developer'. What I didn't know is that his product development acumen is the stuff of SaaS legend! Gabriel is willing to research, try, and optimize. He is a miracle-working IT leader with too many ideas. All the work I have done with Gabriel has helped to drive my industry forward as a whole, not just solve customer needs.

Gabe is not only a fantastic developer, he's also a lovely colleague. He quickly got to work building what we asked for, and he did it well in a reasonable time frame at a reasonable price. We would love to have him on our team full-time if it were possible. We would absolutely hire him again without reservation.
Kimberly Pace Becker, Ph.D.

What Gabe delivered completely exceeded my expectations. Within one week, he created a streamlined consultation process that other consultants had struggled with for months. He's exceptionally smart with a rare ability to make complex technical processes feel simple. He quickly understood my needs, translated them into practical solutions, and saved the attorneys at my firm hours each week.
