About

I’m a Computer Engineer - B.S. in Computer Engineering from the University of Texas at Dallas (Dec 2025) - who works comfortably across the hardware/software boundary. My background runs from high-voltage battery management systems and embedded C firmware to production full-stack platforms and self-hosted infrastructure.

Previously a Full-Stack Software Engineer at TickerTrends, I now work as a Logistics Operations Engineer at KNAPP. Outside of work I run a Raspberry Pi homelab, and I’m a licensed amateur radio operator (KJ5QXS) currently building a VHF/UHF ground station.

Focus areas

Embedded systems + hardware integration
Full-stack platforms + data pipelines
Infrastructure, automation, and reliability

Tooling mindset

I optimize workflows with scripts, structured logs, and clear operational docs - on both the bench and the backend.

Experience

Roles across full-stack software, IT/automation, and embedded hardware engineering.

Full-Stack Software Engineer - Financial Analytics Platform

Jan 2026 - Present

TickerTrends

Built a production report platform delivering financial trend metrics using Playwright rendering, async job orchestration, WebSocket progress streaming, S3 caching, block-based templates, and LLM-powered summary generation.
Hardened production security by patching ~70 SQL-injection vulnerabilities across 27 service files, optimizing YoY computation from O(n²) to O(n), and preventing Chromium OOM failures via concurrency limits.
Re-architected cron orchestration - migrated tracking from Redis to PostgreSQL, added health/error metadata across 39 scheduled workloads, and isolated processing onto dedicated backend infrastructure.
Built resilient ingestion and analytics pipelines over social, search, web, and RSS sources, handling Cloudflare-blocked responses, malformed feeds, rate-limited APIs, and multi-year backfills.

Demo Repo

IT Support Specialist

Jul 2025 - Jan 2026

Young and Associates Inc.

Designed and deployed FastParse, a Python GUI tool that parses bank-issued PDF statements into structured accounting data and imports transactions directly into QuickBooks - eliminating a paid third-party dependency.
Automated depreciation/amortization workflows with a Python bot for ATX, raising data-entry throughput from 2.7 to 12.5 accounts per minute while reducing manual errors.
Recovered critical data from a compromised BitLocker-encrypted NVMe drive via forensic-safe imaging, decryption analysis, and a full Windows rebuild to restore business continuity.

FastParse

Systems Engineer - Battery Management System

May 2024 - Dec 2024

Dallas Formula Racing

Designed and assembled a 720 V high-voltage BMS in Altium Designer; produced a functional prototype that passed all electrical safety tests.
Developed embedded firmware for Texas Instruments battery-management hardware to monitor voltage, current, and I2C temperature sensors (TMP100) for real-time thermal monitoring and early fault detection.
