Kita Pairojtanachai

I'm Kita Pairojtanachai, a full-stack software engineer based in Greenville, South Carolina with 6+ years of professional experience. I've built everything from enterprise resource planning systems to scientific research tools, working across banking, logistics, energy management, and academia.

I thrive on modernizing legacy systems, designing robust architectures, and delivering end-to-end solutions. Whether it's migrating a FedEx integration from SOAP to REST, building UI components that handle 10K+ row datasets, or setting up Kubernetes deployments — I bring both technical depth and a practical mindset to every project.

I hold a Master's in Computer Science from Clemson University (GPA: 3.9) and a Bachelor's in Information and Communication Engineering from Chulalongkorn University in Bangkok. I speak Thai and English.
