What I'm looking for

I seek senior roles building scalable, secure cloud-native platforms that leverage AI/ML and data engineering, with strong CI/CD, IaC, and opportunities to mentor engineers.

I am a Principal Software Engineer with over 9 years of experience building scalable backend systems, data engineering pipelines, and AI-enabled products using Python and AWS. I focus on delivering production-ready services that combine ML, RAG/LLM integrations, and robust cloud infrastructure.

I have led cross-functional teams and architected solutions such as a crypto trading platform, an NFT searchable datalake, and speaker-diarization meeting automation, emphasizing security, scalability, and observability. I regularly implement CI/CD, infrastructure-as-code, and test-driven development.

My technical work spans data warehousing, ETL orchestration with Airflow, REST APIs (FastAPI/Django/Flask), and multimodal LLM integrations using OpenAI, Anthropic and grok. I also design real-time dashboards and monitoring with Grafana, InfluxDB, and message systems like RabbitMQ and Celery.

I am pragmatic and hands-on, mentoring engineers, driving best practices, and delivering measurable product outcomes. I seek opportunities to build reliable, data-driven platforms that empower teams to act faster and smarter.
