What I'm looking for

I am seeking a senior full‑stack/AI role focused on scalable systems, DevOps automation, production ML/LLM, collaborative teams, strong CI/CD practices, and opportunities to lead architecture and measurable impact.

I am a Full-Stack & AI developer with extensive experience building scalable backend systems, data pipelines, and production ML/NLP services. I designed ETL pipelines for real-estate analytics, built AI-driven assistants powered by GPT-3, and delivered realtime dashboards and APIs that improved decision-making and availability.

I led migrations to containerized microservices, implemented CI/CD pipelines, and created reusable service templates adopted company-wide to accelerate development. I collaborate closely with product and UX teams to align AI features with business goals and deliver intuitive interfaces.

My background spans frontend, backend, data engineering, and DevOps, and I bring strong test-driven practices, hands-on cloud/infra skills, and a focus on automation and measurable outcomes. I am motivated to build reliable, performant systems and continuously improve through experimentation and iteration.
