What I'm looking for

I seek roles building backend, data, and cloud systems that leverage AI workflows; I value ownership, observability, collaborative teams, and opportunities to improve model reliability and production robustness.

I am a senior software engineer with 8+ years building backend platforms, data pipelines, and cloud-native services across AdTech, FinTech, EdTech, and content personalization. I specialize in Python (Django), AWS, SQL, and event-driven systems.

Recently I focused on AI agentic workflows and LLM training evaluations, debugging complex repositories, writing tests, and delivering structured feedback that improves model behavior. I have hands-on experience with SFT, RLHF, DPO, RAG, and prompt/context engineering.

Throughout my career I have built REST/GraphQL APIs, microservices, ETL/ELT pipelines with Apache Airflow and AWS Glue, and production-ready observability and rollout practices. I routinely collaborate on performance investigations, incident triage, and cost-control measures in cloud environments.

I mentor engineers, maintain onboarding and runbook documentation, and contribute to maintainable test-first development practices. I deliver reliable, testable systems that balance performance, observability, and safe rollout strategies.
