Eugene Lacatis

Lacatis Construction

• ▸Owned the full lifecycle of ambiguous internal tooling projects end to end. Scoped problems with no prior specification, defined requirements, built solutions, and maintained them in production as business needs evolved.
• ▸Built an invoice PDF generator and parts inventory CRUD system from scratch. Reduced invoice creation time by 90% and annual parts costs by 26% by independently scoping, building, and iterating through direct user feedback.

Cybele Health

• ▸Designed the model architecture for a clinical chatbot grounded in a doctor's own knowledge base, evaluating open-source vs. closed-source LLMs against HIPAA constraints and building the case that informed the final model decision.
• ▸Built a RAG pipeline over doctor-specific clinical content with Google MedGemma as a domain-aware guardrail layer, restricting responses to verified provider material.
• ▸Diagnosed root cause of generic MVP responses through clinician-led evaluation, tracing the issue to limited source-corpus coverage, and proposed a prioritized retrieval-fallback design to address it.

Kaiser Permanente

• ▸Abstracted multi-step Splunk log analysis workflows into reusable macros and conditional panels; integrated regional error breakdowns via dynamic pie charts to cut incident triage time for 1000+ Pharmacy IT staff.
• ▸Implemented parameterized SPL queries and reusable macros to trace cascading error origins across log hierarchies, reducing search latency by 70% across 100k+ daily log entries.
• ▸Designed cross-system Splunk dashboards monitoring error rates, latency spikes, and system dependencies; surfaced performance bottlenecks in pharmacy's Rx ordering system.
