Data Engineer III

USAA / 2024 - Present

• Build and maintain high‑volume data pipelines (~26M records/day) that power credit‑risk and payment‑security applications.
• Delivered a migration of a key risk dataset from a business‑managed tool into the enterprise data platform,improving data quality, lineage, and auditability for regulated reporting.
• Automated model generation: created Python utilities to turn written data specs into staging/load models and validate them against SQL equivalents,reducing manual effort and errors.
• Owned feature work across account‑level risk views and payment‑protection logic; ramped quickly on mid‑stream handoffs and kept delivery on schedule.
• Pitch in on security/maintenance tasks when bandwidth allows to reduce backlog and keep compliance strong.

Founder

Guadalupe Automation / 2025 – Present

• Building AI automation consultancy helping SMBs deploy secure, internal AI infrastructure and train teams to automate their own workflows.
• Install private automation environments (n8n, Make) integrated with generative AI, then teach clients to identify and eliminate busywork permanently.
• Focus on transforming organizations into AI-first operations where employees become automation architects rather than data movers.

Co‑Founder & Chief Marketing Officer

Fit & Flourish / 2024 – 2025

• Built an autonomous ad‑creative system using Meta Ads API, n8n, OpenAI image generation, and a multimodal supervisor with a light human‑in‑the‑loop (Discord). Result: 40,000 leads at ~$0.29 CPL (~1/5 the industry average).
• Owned marketing analytics and reporting—pulled performance via API, ran aggressive A/B tests, and auto‑deployed new creatives based on real‑time results.
• Developed the camera‑based sizing calculator: generated a 3D body mesh (Meshcapade) and computed bust/underbust from geodesic paths on the mesh surface to map measurements to size tables.
• Implemented proactive AI customer outreach: MailChimp‑driven surveys and automated follow‑ups to conduct lightweight interviews and increase engagement.
• Owned the e‑commerce site, referral flow, and ad‑tracking dashboards underpinning launch operations.

• Led 7 developers building a serverless, cloud‑native app across 25+ AWS services.
• Built a receipt pipeline (S3→Lambda→Textract) and a fine‑tuned GPT‑3 multiclassifier to assign 100+ categories; structured JSON responses before model function calling was common.
• Implemented security practices aligned to ISO‑style controls for account/transaction data access.
• Shipped LLM‑powered advice features (GPT‑4/LLaMA2) with evaluation loops to keep quality high.
