What I'm looking for

I seek roles where I can build cross-platform features, automate cloud CI/CD, and work on user-centered products within collaborative, product-focused teams.

I am a Full Stack Software Engineer experienced in building and deploying product features across web, backend, and mobile environments. I have practical expertise in JavaScript (React, Node.js), Swift (iOS), and Kotlin, and I design REST APIs, automate cloud workflows with AWS, and integrate scalable systems that support real-world user experiences.

At PlotTwist I implemented analytics tracking, optimized iOS performance using concurrency, automated TestFlight builds with Xcode Cloud, and rebuilt analytics dashboards and notification systems (React, Node.js, Postgres, Twilio, AWS Lambda). I deliver user-centered, reliable software and thrive in collaborative teams focused on product impact.
