Governed conversational data platform

I architected and built a governed conversational data and visualization agent: it retrieves business knowledge, answers business questions, runs governed queries from that context, reasons over results, and builds charts without making the LLM the data boundary.

Python FastAPI LangGraph Langfuse

Moved analytics discovery toward self-service by connecting a multi-LLM graph runtime with knowledge retrieval, governed Trino execution, answer reasoning, chart generation, prompt tracing, and a richer Open WebUI experience. The natural-language analytics path reduced query time by about 40% for supported workflows.

CI/CD onboarding and developer-experience framework

Created an in-house YAML-driven CI/CD framework that let teams onboard projects with very little friction while keeping validation, security scans, deployment behavior, and Jira status updates standardized.

In-house CI/CD YAML Jenkins Docker Kubernetes (OCP)

Improved developer experience, reduced CI/CD onboarding time by about 40%, and increased CI/CD adoption several-fold by replacing bespoke Jenkins pipelines with a small project-level YAML file, reusable templates, automated quality gates, and Jira-triggered delivery flows.

Browsing-log analytics and safe-browsing pipelines

Built browsing-log ingestion and analytics pipelines for safe-browsing classification, audience management, cohort creation, and pattern-based downstream data products.

NiFi Spark Airflow Python

Turned raw browsing activity into governed analytical signals: threat classification, spam URL marking, audience segments, browsing-pattern cohorts, and reusable data products.

Retail adjacency and store-flow analytics

Built reusable analytics workflows for cross-shopping, category adjacency, aisle-flow, and store-flow analysis across departments, categories, and products.

Spark Python Power BI Airflow

Helped retail teams move from isolated category views to placement and assortment decisions associated with up to 20% sales-growth impact.
