Shane Iseminger

Lead/senior software engineer with 25+ years of hands-on experience in software engineering, software architecture, system design, performance, and security. I especially value projects doing meaningful work on a team that values clean code, creative problem solving, and thoughtful architecture. I spent decades expanding and refining my skills, matching the pace of the web and mobile technology industry as it's grown and changed.

For the last decade-plus I've focused on high-ownership, minimal-oversight work across the domains of software engineering, software architecture, system design, infrastructure and security, leading teams, mentoring junior developers, and directly working with and supporting enterprise clients like Nasdaq, AAA, Accenture, Pepsi and Paypal. My early projects include UI/UX, design, frontend, backend, data modeling and optimization, and often serving as a jack-of-all-trades for startups as well as established enterprise clients. I'm a strong believer in flexible code, type safety, testing, SOLID principles, systems thinking and constant learning.

I actively seek out solutions to problems and opportunities to learn rather than waiting for them to come to me.

• Implemented, optimized, maintained and owned PostgreSQL data storage and advanced SQL queries, including event stores and time-series data.
• Developed in-depth visual and written technical documentation of our implementation of DDD, CQRS and other architectures, and mentored junior developers on adopting those architectures.
• Moved many workloads from cron-based execution to asynchronous pub/sub event-based processing.
• Managed payment processing and accounting code.
• Consistently reduced cloud spend, sometimes 25% at a time, allowing headroom for new features without budget increases. Wrote many more third-party API integrations, including workflow-based multi-vendor integrations.
• Implemented Agile workflows. Wrote microservices in Golang.
• Consistently reduced technical debt.
• Kubernetes implementation allowed us to consistently deliver 99.99% uptime SLAs.
• Instrumental in leadership and implementation of SOC2 compliance work.
• Led a dev team of 2–8, including hiring, code review, and technical leadership and direction.
