01 — The approach

I build the systems that make complex data useful.

With 10+ years in production Java engineering across Oracle, Bosch, and WorksApplication, I take end-to-end ownership of backend platforms: from system design and data ingestion to production operations and continuous improvement.

My work centers on event-driven architectures, search and data platforms, Kafka pipelines, cloud-native services, and enterprise workflow automation. I pair hands-on technical design with incident ownership, code reviews, mentoring, and cross-functional delivery.

Thoughtful engineering.
Real-world impact.

A few things I’ve helped bring to life — from high-volume data platforms to applied AI.

Spark → Oracle DB → Kafka → OpenSearch
01

Data & search platform

OCI Usage Consumption Platform

A cloud-based, event-driven platform for technology-consumption workflows. Work included data ingestion, indexing, search, integrations, notifications, shared data services, and applied-ML exploration.

Challenge Keep high-volume ingestion and search reliable across scheduled and incremental load scenarios.

Approach Parallel Kafka consumption and OpenSearch bulk indexing, Spark extraction, sequential indexing, safe alias promotion, and operational recovery controls.

Outcome Improved indexing throughput by resolving ingestion and search bottlenecks.

Applied ML proof of concept

Extension Decision Recommendation

Contributed to a Python/FastAPI service that recommends active trial plans and permitted extension options for SPM decision workflows while maintaining an auditable human-review path.

Conversational AI proof of concept

GenAI Chatbot for URL & Opportunity Creation

Led a conversational-AI proof of concept combining BlenderBot and vector retrieval for sales-rep intent recognition, with workflow UI and Search Service REST APIs for guided URL and opportunity creation.

View details

Technical owner for a cloud-based, event-driven data and search platform supporting usage-consumption workflows, spanning ingestion, indexing, APIs, integrations, notifications, and applied-ML exploration.

Platform & architecture

  • Leads technical design across the platform and architecture reviews across teams.
  • Designed resilient monthly and rolling-three-month load orchestration with independent Spark extraction, sequential indexing, safe alias promotion, recovery controls, timestamp-based batch pairing, and protections against overlapping or out-of-order daily loads.
  • Built REST APIs for plan details, account-plan views, consumption trends, products, rate cards, saved searches, extension data, and chatbot-facing queries.

Scale & engineering leadership

  • Improved a Kafka, Spark, and OpenSearch pipeline through parallel processing and bulk-indexing practices for high-volume workloads.
  • Owns CI/CD, containerization, Kubernetes deployment strategy, incident response, and observability.
  • Drives cross-team delivery, mentors engineers, and conducts code reviews.
