Hi, I'm Jerry Holland
Senior Software Engineer | 12+ Years Experience
Building scalable, high-performance applications with expertise in full-stack development, cloud architecture, and system optimization.
About Me
Senior Software Engineer with 12 years of experience spanning full-stack development, back-end architecture, and embedded systems. I specialize in building scalable, high-performance applications using modern cloud technologies and microservices architecture.
Currently working on enterprise cloud infrastructure modernization, migrating legacy systems to modern containerized architectures. Specializing in performance optimization, real-time data processing, and building scalable SaaS solutions for industrial applications. Recent work includes designing RESTful APIs serving millions of daily requests, implementing message queue systems for asynchronous processing, and creating interactive visualization tools for complex datasets.
Passionate about performance tuning, system optimization, and mentoring developers. I believe in test-driven development, Agile best practices, and continuous learning to stay at the forefront of technology.

Problem-Solving Highlights
Challenge
Legacy authentication system causing frequent user lockouts and poor session management
Solution
Implemented modern OAuth/OIDC flow with refresh token management and dual authentication provider support for seamless failover
Impact
Reduced authentication support tickets by 75%, improved user satisfaction scores, and enabled single sign-on capabilities
Challenge
Complex database queries timing out in production, causing application slowdowns and poor user experience
Solution
Analyzed execution plans, identified bottlenecks, added strategic indexes, and refactored complex CTEs for better query optimization
Impact
Reduced query execution time from 45 seconds to under 3 seconds, dramatically improved user experience and system throughput
Challenge
Manual data import process prone to errors, consuming significant staff time and causing data quality issues
Solution
Built automated import system with comprehensive validation, error recovery mechanisms, and transactional rollback capabilities
Impact
Eliminated 95% of data import errors, freed up 10+ hours per week of staff time, and improved data quality metrics
