About

πŸ‘‹ Hi, I'm Tabitha β€” a full-stack (but let's face it, mostly backend) software engineer who thrives at the intersection of platform integrity, system design, and operational resilience in fintech. I'm passionate about building systems that endure, especially when milliseconds and accuracy matter. From intern to senior engineer in 3.5 years, I've rapidly grown into architecting fraud detection platforms and instant decisioning systems that protect financial transactions at scale. I focus on clean, testable code and thoughtful architectural decisions that balance speed with reliability in high-stakes environments. I leverage AI coding tools as a strategic force multiplier β€” applying my fintech domain expertise to guide implementation while ensuring robust, compliant solutions. Beyond writing code, I'm deeply invested in engineering culture and team growth. I mentor engineers (and remain a lifelong learner myself), improve onboarding processes that reduce time-to-productivity, and regularly contribute to docs, reviews, and architectural decisions that shape how we build. As a trusted deployment coordinator and incident commander, I'm known for clear judgment under pressure, cross-functional coordination, and driving not just resolution but the structural fixes that prevent repeat incidents. I lead with extreme ownership in high-stakes environments, from design reviews that prevent outages to experimentation frameworks that enable safe innovation. I bring long-range systems thinking to complex engineering problems, whether that's designing event-driven architectures or implementing observability that actually helps teams ship faster. When I'm not coding, you'll find me in my garden πŸͺ, tending to my bees 🐝, or engaging with my book clubs πŸ“š β€” hobbies that keep me thinking creatively, nurturing my curiosity, and collaborating effectively. Let's connect β€” I'm always excited to discuss building resilient systems and empowering engineering teams.
