Jeff Schaefer

Building Technology Solutions for 15+ Years

From first developer at a recruiting startup to founder of a $100K/month business - I've built systems that scale from MVP to enterprise.

The Journey

Early Career: Building from Zero

Started as the first developer at ApplicantStack, a recruiting platform serving just 4 employees. Over 8 years, built the entire technical infrastructure - from database architecture to customer-facing features - as the platform grew to serve 1000+ enterprise clients.

Key Achievement: Scaled platform from zero to serving millions of users while maintaining sub-second query performance.

Entrepreneurship: Building a Business

Founded Schaefer Land Holdings LLC, growing it to $100K+ monthly revenue with a 7-person distributed team across US and Philippines. Built entire technology stack as competitive advantage - from marketing automation to data processing systems.

Key Achievement: Created automated marketing system handling millions of touches across email, SMS, RVM, and direct mail.

Current Focus: Steel Valley Technologies

Bringing enterprise-level technical expertise to small businesses that need specialized work but don't have (or don't want) dedicated technical teams. Building custom solutions across applications, integrations, automation, and data systems.

Mission: Help small businesses solve complex technical problems without the overhead of maintaining full technical teams.

My Approach

Customer-Centric Development

Having built and run a business myself, I understand that technology exists to solve business problems - not the other way around. Every technical decision I make considers your actual business needs, constraints, and resources.

Full-Stack Thinking

I've built systems end-to-end - from database schema to user interfaces, from server infrastructure to email deliverability. This comprehensive view helps me design solutions that work well across the entire stack, not just in isolation.

Building for Scale

Starting as employee #1 at a startup that grew to serve 1000+ enterprise clients taught me how to build systems that can scale. Even small businesses benefit from architecture that can grow with them.

Real-World Constraints

As a business owner who's managed limited budgets and distributed teams, I understand the constraints of small business. I build solutions that work within your reality - not theoretical perfect-world scenarios.

Beyond Code

When not building software, I'm a Catholic father of four boys, homeschooling with my wife Marie in Coatesville, PA. I'm also a certified flight instructor with 15+ years of teaching experience - which turns out to be surprisingly relevant to explaining complex technical concepts in accessible ways.

I stay current with technology by coding daily (see my GitHub contributions below). Great consultants don't just talk about technology - they actively practice the craft.

Daily Commitment to Craft

This is my actual GitHub contributions graph. I'm not a consultant who used to code - I'm a developer who consults. That daily practice keeps me current with modern development practices and ensures I can adapt quickly to new technologies.

GitHub Contributions Graph

365 days of code. 365 days of understanding what it takes.
