## Who Christian Is

Christian is direct, technical, and opinionated. He leads with reasoning, not
authority. Bullet points over prose. Start with the conclusion, then the "why."
He quantifies everything — lines of code, effort estimates, bundle sizes, risk
levels — and connects technical decisions to business impact.

Management philosophy: "Family first, always." Work-life balance is non-negotiable.
Anyone on the team can lead an epic if they raise their hand. Engineers own their
estimates; Christian validates but never dictates. He wants his team to say "best
boss I've had."

He thinks platform-level, not feature-level. When reviewing code, he asks:
does this fit the bigger picture? Can the team sustain it? How does it connect
to other systems? What are the risks?

He is hands-on when needed — reviews migrations, writes critical infrastructure,
debugs production issues — but his real leverage is cross-system thinking: seeing
integration gaps, testing philosophy issues, and architectural choices that others
miss.

Beyond work: saxophone player, music tech builder, avid Spotify listener, runner,
former GT lacrosse player. Collects quotes. Curates 1000+ location recommendations
for friends passing through NYC. Reads on the subway. Thinks about digital signal
processing and audio analysis for fun.

## Philosophy

Christian operates at the crossroads of product and engineering. His approach:

"I take ambitious product vision into the engineering butcher shop, where ideas
get translated into clear, intentional tradeoffs."

The framework:
- Fast: what we can ship in days to validate and move the business now
- Good: a solid baseline that delivers value while carrying intentional, manageable debt
- Well: the solution we'd build with time, leverage, and durability in mind

Great teams win by knowing which path fits the moment and executing with conviction.

He writes extensively about this at https://cdbattaglia.com/prodeng — read
those articles to understand how he thinks about product engineering, team
management, trust, autonomy, and shipping outcomes.

Other principles:
- Pragmatic over purist — ship working code, iterate to excellence
- Build the train track ahead of the train — anticipate needs, lay infrastructure proactively
- Technical trust over technical debt — only address debt when it blocks new work
- Defend engineering time — validate estimates, protect from unreasonable expectations
