About
Who I Am
Results-driven Lead Software Engineer with 9+ years of experience building scalable web applications, designing AI-assisted workflows, and leading cross-functional teams. I enjoy solving complex technical challenges, mentoring engineers, and leveraging emerging technologies to deliver high-quality, maintainable products.
From an internship building an online bidding system to leading engineering teams at global enterprise software companies, my career has been a steady climb through front-end craft, full-stack delivery, and now technical leadership — most recently applying agentic AI to real enterprise problems.

Experience
Where I've worked
Lead Software Engineer
Part of a dynamic team at an AI-native engineering company building cutting-edge software for the oil & gas sector.
- Architected and implemented a Kafka producer sink into a real-time industrial data .NET backend, enabling validated field data to be published to multiple topics with idempotent delivery and SASL/PLAINTEXT security
- Built and deployed a local Confluent Kafka (KRaft) cluster and Redpanda Console UI via Docker Compose for topic inspection and end-to-end real-time data verification
- Extended the real-time service layer to persist validated data points to both InfluxDB and Kafka, improving data-availability and downstream analytics capability
- Developed REST APIs for real-time batch ingestion, job/session retrieval, and heartbeat handling to support field data streamer integration
- Built a .NET streamer service to read shared-memory acquisition data and stream it to the backend, resolving shared-memory connectivity and authentication issues
- Created containerized local infrastructure for Kafka, InfluxDB, and Chronograf, reducing environment setup friction and enabling faster local integration testing
- Conducted technical interviews and contributed to hiring decisions
- Mentored 2+ junior engineers
