Tim Kim

Software Engineer · Orlando, FL

I am a mission-driven Software Engineer specializing in backend development and scalable cloud infrastructure. My transition from technical solutions engineering was fueled by a fascination with the elegance and accessibility of code, leading me to self-study computer science and pivot into full-time engineering.

I am passionate about building robust systems using Java, Spring Boot, and AWS (Lambda, SQS, EventBridge, Kafka). I thrive in collaborative environments where I can apply my dedication to continuous learning and system optimization to create impactful solutions that improve the lives of others.

    Interests

    I’ve always loved the thrill of competitive gaming, spending my fair share of time in LoL, TFT, Valorant, Hearthstone, and SC2. Now that I'm a dad to my daughter, Joy, time is precious, so I mostly stick to Brawl Stars with my brothers.

    When I want to unplug, I swap the keyboard for cardboard. I’m a huge fan of deep strategy board games, with Avalon, 7 Wonders, Dune: Imperium, Search for Planet X, and Alchemists currently hitting the table most often.

    Beyond gaming, I stay active through basketball, soccer, and ultimate frisbee. I also look forward to my weekends teaching 12th-grade Sunday School.
