Bio

I'm a Software Engineer based in Los Angeles, CA with 5+ years of experience building backend services, internal developer tools, CI/CD systems, and data pipelines across Linux, eDiscovery, media processing, and SaaS environments. My journey started in high school writing scripts and bots for Runescape, and has since grown into production work on release-intelligence platforms, enterprise search systems, and cloud-based media pipelines.

I currently work at 10ZiG Technology, where I owned the rollout of a real-time release intelligence dashboard aggregating 16 daily Jenkins pipelines and 1,000+ regression tests, and scaled distributed CI/CD execution to cut regression runtime from 10 hours to 3. Between iPro Tech and 10ZiG I built Parlays.gg as an independent project — a Next.js sports analytics app with Stripe, JWT auth, and ETL pipelines pulling from ESPN and odds APIs. At iPro Tech I contributed to backend services and Elasticsearch-based retrieval workflows for an enterprise eDiscovery platform, and at Ateliere Creative Technologies I developed Python and Node.js services for a cloud-based media platform on AWS.

I enjoy correctness-sensitive backend work — CI/CD, release automation, ETL, and internal tooling that replaces manual workflows. Beyond coding, I enjoy working out, traveling, and playing chess and poker.

Work Experience

Software Engineer

10ZiG Technology

Sept 2024 - Present

  • Owned the design, implementation, and rollout of a real-time release intelligence dashboard aggregating 16 daily Jenkins pipelines and 1,000+ regression test results per day, giving engineering teams a single operational view of release health, failures, and test trends.
  • Scaled Jenkins-based CI/CD infrastructure with distributed execution, reducing regression runtime by 70% from 10 hours to 3 hours and shortening engineering feedback loops.
  • Built internal developer tools and release automation systems in Python and JavaScript for Linux firmware and 10ZiG Manager, improving device management, release operations, and engineering workflows.
  • Created Python and Bash benchmarking tools for Linux environments to validate firmware changes, detect performance regressions, and support release readiness decisions.

Software Engineer

Independent Project – Parlays.gg

Jan 2024 - Sept 2024

  • Built and deployed a full-stack sports analytics web application using Next.js, MongoDB, Stripe, JWT authentication, ESPN data, and odds APIs.
  • Implemented ETL data pipelines that extracted game, score, and odds data from third-party APIs, transformed inconsistent team/date/market formats, and loaded normalized records into MongoDB for dashboard and prediction workflows.

Software Engineer

iPro Tech

Sept 2021 - Jan 2024

  • Contributed to backend services and Elasticsearch-based retrieval workflows for an enterprise eDiscovery platform, supporting full-text search across large legal document collections.
  • Built ingestion and validation tooling in Python, C#, and SQL to help process uploaded legal documents into indexed, searchable datasets and reduce manual data preparation workflows.
  • Implemented and maintained GitLab CI/CD pipeline stages for build, test, and deployment automation across multiple environments, improving release consistency and developer feedback loops.

Software Developer

Ateliere Creative Technologies

March 2020 - Sept 2021

  • Developed Python and Node.js backend services for a cloud-based media platform supporting ingest, metadata, packaging, and delivery workflows.
  • Supported AWS-based tooling for media packaging and encoding pipelines in a distributed cloud environment.
  • Built and maintained integration workflows for delivery endpoints, helping automate media processing and asset delivery operations.
