What I'm looking for

I seek senior engineering roles building scalable AI/ML platforms or backend systems, in collaborative teams where I can mentor, drive architecture, and deliver production ML integrations.

I am a senior software engineer with extensive experience building scalable AI and backend platforms at enterprise scale, focusing on Java, Spring and cloud-native architectures. I have led design and implementation of metadata schemas, APIs, migration tooling and integrations for generative LLMs and predictive models, enabling billions of predictions and significant cost savings.

I collaborate closely with product, data science and cross-functional teams, mentor engineers, and deliver production-ready systems such as retrievers (RAGs), Data Cloud metadata entities, and a rollback-safe migration tool adopted across multiple teams. My background spans finance, healthcare, and startups, with hands-on experience in NLP, model deployment, and full-stack development.
