What I'm looking for

I want to build and scale backend services that serve real users, with strong engineering practices like CI/CD and containers. I’m looking for ownership, mentoring-minded teams, and opportunities to grow into AI-enabled product development.

I’m a backend-focused software engineer who builds scalable systems with Python and Django, with real-world experience supporting an insurance product serving 200K+ daily active users. I redesign backend architecture to be more dynamic—improving scalability, performance, and how easily new features expand over time.

Most recently, I’ve taken ownership of backend delivery end-to-end: RESTful API design and integration, automation via Jenkins CI/CD pipelines, and production releases using Docker containerization. Alongside this, I’ve contributed to Flutter app development while managing work within a team environment.

Before that, I developed conversational AI using RASA and Django—building a chatbot with 50+ languages and voice accents, and integrating third-party services like Facebook Graph API and Stripe. I also enjoy creating impactful projects that combine AI and real user experiences, and I’m driven by continuous learning, performance, and mentorship through tech.
