Shipping durable software for problems worth solving.

I build software for people doing complicated, important work — most recently in healthcare and genomics research — and I care more about whether the right thing got built than which framework it was built in. The work I'm drawn to is 0-to-1: high autonomy and ownership, complex domains, and partnering directly with the people who'll use what I ship.

For most of the past two years I worked across two threads. At the Eccles Institute of Human Genetics, I shipped three independent bioinformatics web tools in my first seven months and then led SV.iobio — a real-time interactive visualization for genomic structural variants designed for both researchers and clinicians. In parallel I was building SiteLoom — a HIPAA-compliant collaboration platform for clinical research offices — through my company Susync Software, part-time for most of it and full-time more recently. Different domains, same shape of work: own the problem, learn the field, build the thing, ship it.

I'm winding the company down now and looking for the next place I can grow with: a palpable mission, people I learn from, and room to keep contributing more over time.

An excellent mutual fit matters more to me than geography — I'm open to relocating for the right opportunity.

About
Bio

I've been writing code since 2018 — across SQL databases, full-stack web, interactive D3 visualizations, bioinformatics tooling, and HIPAA-compliant AWS infrastructure. My path in was sideways: I started writing code to build tools and run data analytics for my graduate research team in experimental psychology, and never stopped — I carried it into clinical-research operations, then into engineering full-time.

Within clinical research, I became Activation and Database Administrator — the team was juggling 500+ new study offers a year on spreadsheets, so I built them a SQL database. It became a tool the team relied on every day (and still does) — and, looking back, the proof-of-concept that eventually became SiteLoom. That's where I learned what good software has to feel like: from inside the workflow it's serving. It's still the lens I design through.

For two and a half years I was at the Eccles Institute of Human Genetics, where I shipped three independent bioinformatics web tools in my first seven months and went on to lead SV.iobio, a real-time interactive visualization platform for genomic structural variants used by researchers and clinicians. In parallel I founded Susync Software to build SiteLoom, a HIPAA-compliant work-management platform for clinical research offices to coordinate with external partners — CROs and pharmaceutical sponsors. I iterated closely with a research-office partner who eventually requested pilot funding from their institution; we never launched the pilot, and I'm winding the company down.

I'm pragmatic about stacks and never hesitate to pick up a new tool when it's the right fit. What drives me is solving real problems with thoughtful, usable software.

What I value

Growth, contribution, mission. Teams that take the people on the other end of their software seriously.

How I work

Pragmatic about stacks. Stubborn about problems. Comfortable being the only engineer in the room and learning whatever the domain demands.

SiteLoom — Susync Software

Founder & Engineer · 2024 — 2026

A work-management and collaboration platform purpose-built for clinical research offices to coordinate with external partners (CROs, sponsors). I founded the company, led product, and iterated directly with a research-office partner — translating user feedback into roadmap and shipped features. Architected the HIPAA-compliant AWS infrastructure: backup and disaster recovery, audit logging, BAA-covered services, and the access controls clinical data requires. Currently winding the company down.

SV.iobio

Lead Developer · Eccles Institute · 2024 — 2025

An interactive web tool for analyzing structural variants (SVs) from VCF files, integrated into Mosaic — a genomics case-analysis platform used by researchers and clinicians. Users link a VCF from Mosaic or load one locally, then explore variants against a dynamic chromosome map; clicking any SV surfaces annotations: overlapping genes, phenotype associations, and population frequency. HPO term and gene-of-interest filtering quickly surface clinically relevant alterations. Handles multiple samples with thousands of variants each; built around heavy interactive D3 for performance at that scale.

Simpheny.iobio

Web Software Developer · 2023 — 2024

A real-time web app for exploring phenotypic similarity between individuals across multiple curated populations — used by clinicians and researchers to interrogate undiagnosed cases of suspected genetic origin. Users bring their own case (a set of HPO terms) or pick from available cases, then compare against populations like the UDN and Orphanet; results are surfaced through interactive visualizations with filtering by population. Rust on the backend for speed over the similarity index, Vue + D3 on the front for the explorer. Built solo in roughly seven months.

Pheno-Plus

Web Software Developer · 2023 — 2024

A SMART on FHIR app embedded directly in the EMR that extracts HPO (Human Phenotype Ontology) terms from unstructured clinical notes via NLP, then lets users review and curate the results in place. Cut the original manual workflow time roughly in half. The hard parts were less about the model than fitting cleanly into the clinician's existing flow inside the EMR.

Founder & Engineer

Susync Software Inc · SiteLoom

Founded the company and built SiteLoom from scratch — a HIPAA-compliant work-management platform for clinical research offices to coordinate with external partners (CROs, pharmaceutical sponsors). Sole engineer. Iterated directly with a research-office partner who requested pilot funding from their institution; we never launched the pilot, and I'm winding the company down. Architected the full AWS stack — ECS, ECR, Amplify, DynamoDB, Cognito, S3 — with backup and disaster recovery, audit logging, and BAA-covered services throughout, vetted via Vanta.

2024 — 2025

Senior Software Developer

University of Utah · Eccles Institute of Human Genetics

Led development of SV.iobio, a real-time interactive visualization for genomic structural variants — used by researchers and clinicians to rapidly identify disease-causing variants. Integrated with the Mosaic case-analysis platform; supports multiple samples with thousands of variants each. Worked across bioinformatics tooling, multiple unified genomics data sources, and SQLite — software, visualization, and data plumbing in equal measure.

2023 — 2024

Web Software Developer

University of Utah · Eccles Institute of Human Genetics

Rapidly mastered essential genomic data formats and biological concepts to develop and launch three independent bioinformatics web tools in my first seven months. Designed and built Simpheny.iobio, a phenotype-driven case analysis tool comparing patient profiles against curated populations (UDN, Orphanet) — Rust + SQLite for the comparison index; co-author on the resulting publication (Cooperstein et al., medRxiv 2026). Built Pheno-Plus, a SMART on FHIR EMR-embedded app that extracts and curates HPO terms from free-text clinical notes via NLP, cutting the original workflow time roughly in half.

2022 — 2023 · part-time

Software Consultant

VersaTrial · acquired by Florence Health, 2023

Part-time consulting on clinical-trial workflow software during the lead-up to the company's acquisition by Florence Health.

2020 — 2023

Activation and Database Administrator

Huntsman Cancer Institute · Clinical Trials Office

Designed, built, and administered a SQL database from scratch to track studies in early activation — enabling a single administrator to effectively manage 500+ new study offers per year. The database is still in use by the team today. Authored the full range of SQL: ad-hoc pulls, automated reports, recurring leadership dashboards, and visualizations surfacing workflow bottlenecks. Created flowcharts and stakeholder documentation that improved transparency into how the office actually worked.

2019 — 2020
