01 / Selected systems

Built to perform in production.

Each system pairs a real operating problem with deliberate engineering choices and a measurable result.

01

Enterprise semantic search

Designed a context-aware multilingual retrieval system for fragmented enterprise knowledge across four languages.

Retrieval · Ranking · Evaluation · Multilingual indexing · Production observability
Problem
Knowledge discovery across markets
System
Semantic retrieval and ranking pipeline
Result
100% recall · 0.93 MAR
02

Healthcare recommendation engine

Built data-driven personalization capabilities to improve healthcare-professional engagement and retention.

Behavioral signals · Personalization · Experimentation · Product analytics
Problem
Low relevance in omnichannel journeys
System
Recommendation and decisioning layer
Result
10% retention improvement
03

Reusable AI platform

Standardized the foundations for RAG and agentic use cases so teams could ship on shared patterns instead of rebuilding core infrastructure.

RAG · Tool orchestration · Reusable components · Enterprise controls · Developer experience
Problem
Duplicated AI foundations across teams
System
Shared platform and delivery patterns
Result
Adopted across 8 projects
04

Cloud and delivery optimization

Reworked CI/CD and cloud architecture to reduce release latency, improve operating efficiency, and lower recurring infrastructure cost.

CI/CD · Infrastructure automation · Cost controls · Reliability · Observability
Problem
Slow releases and inefficient spend
System
Optimized delivery and cloud platform
Result
4× faster · $50k+ saved
