Hi, I’m a
What I Do
Data & ML Infrastructure
Data pipelines, GPU/ML platform work, and backend systems — from ingestion through model serving.
DevOps / CI/CD
Self-hosted CI/CD infrastructure, containerized deployments, and cloud infra (AWS/GCP).
Background
Coordinator, LLCLead Engineer (Contractor)March 2026 - September 2026
- Multi-sport LLM fine-tuning pipeline (football, basketball, hockey, golf, endurance) on H100 GPUs: corpus curation, two-layer training architecture, continuous feedback-retraining loop, quantization for vLLM serving
- Built self-hosted CI/CD infrastructure for the end-to-end test suite: serial vs. parallel job split, switched LLM backend to cut per-run cost
- Self-hosted GPU voice pipeline (Whisper STT; benchmarked and swapped TTS engines for latency and compatibility), later shipped as production voice messaging (STT/TTS via OpenRouter) in the web app
- Video/VLM pipeline: Qwen3-VL and Cosmos-Reason2 inference for at-the-snap play/formation detection; iteratively tuned confidence thresholds and frame preprocessing; clip/frame storage on MinIO + Postgres
- Wearable sensor data pipeline (IMU wrist prototype) for athlete movement tracking, plus swing-video pose-estimation analysis
- Third-party data-access gateway (scoped, revocable tokens) evolved into an app store: template registry, per-app data storage, 3-way merge reconciliation for template updates
RalliFounderJanuary 2025 - October 2025
- Built ETL pipelines ingesting live and historical odds, player props, and stats from third-party sports APIs (The Odds API and others) into a normalized Postgres (Supabase) data store
- Designed data model and ingestion cadence supporting a real-time fantasy sports and social betting product
- Sole engineer scaling data infrastructure and product from part-time to full-time (July 2025)
Turbin3Head of Special ProjectsMay 2024 - July 2025
- Taught multiple classes across the Solana stack: 101, frontend, Advanced Solana, and building products
- Traveled globally delivering talks to new engineers entering the space
Trustless EngineeringML EngineerApril 2024
- Built Kubernetes deployments (ArgoCD) and ML infrastructure
- Used Datadog for observability across deployments
LancerChief Technology Officer2022 - October 2023
- Developing MVP for a GitHub extension which allows contributors to be paid immediately on feature merge
- Designing smart contract involving a double escrow system, enabling projects to be funded and developed autonomously and collaboratively
- Creating relationships with future clients and partners to accelerate the development of the Lancer platform
- Formulating pitch deck to raise a seed round for 18 months of runway
Applied IntuitionSoftware Engineer2020-2021
- Developed (full stack) intranet for managing developers, teams, and customers, vastly improving efficiency of all employees
- Helped close multiple million dollar deals through creation of a license dashboard demonstrating client product usage trends
- Improved average customer support response time from > 1 day to < 1 hour through creation, automation, and maintenance of custom Zendesk solution
University of Maryland, College ParkBachelor's - Computer Engineering2016-2020
- GPA: 3.93
- QUEST Honors program focused on business and technology collaboration for solving complex design challenges
HydrazeChief Technology Officer2019-2020
- Designed a novel IOT automatic toilet flushing system that eliminates unnecessary flushes and enhances water conservation, potentially saving facilities thousands of dollars annually
- Developed IOT network with a Raspberry Pi central node which communicates with multiple Arduino micro-controllers attached to toilets and stalls enabling autonomous flushing and data collection
- Created a novel facilities management platform which allowed managers to view bathroom data and device battery levels
Amazon Web Services - DafnySoftware Development Engineer Intern2019
- Enabled mathematical verification of AWS products through compilation from Dafny to Java
