Technical Excellence

I believe in building systems that are not just functional, but elegant. Clean architecture, thorough testing, and performance optimization are non-negotiables.

Team Empowerment

Great products come from great teams. I create environments where engineers feel ownership, take risks, and grow beyond their current capabilities.

Continuous Learning

Technology evolves rapidly. I foster cultures of curiosity, regular knowledge sharing, and experimentation with emerging tools and methodologies.

Strategic Impact

Every line of code should serve a purpose. I align engineering efforts with business goals, ensuring our work creates measurable value for users.

“The best code is written by engineers who feel empowered to make decisions, safe to take risks, and inspired by the impact of their work.”

3 Things I Learned Scaling Pinterest's Ad Platform

Lessons from coordinating iOS, Android, and Backend teams to deliver features for 500M+ users.

Read more

After leading cross-functional teams at Pinterest, three patterns consistently drove success:

1. API Contracts First — Mobile and backend teams align on contracts before implementation. This eliminates late-stage integration surprises and enables parallel development.

2. Feature Flags Are Non-Negotiable — With 500M+ users, every release needs a kill switch. Gradual rollouts (1% → 10% → 100%) catch issues before they become incidents.

3. Cross-Platform Parity Matters — iOS and Android users expect identical experiences. We maintained feature parity checklists and shared test cases between platforms.

How I Structure 1:1s With Engineers

A framework for weekly conversations that actually drive growth and unblock problems.

Read more

After mentoring 50+ engineers, I've refined my 1:1 structure to maximize impact:

The 30-Minute Framework: - First 10 min: Their Agenda — They lead with what's on their mind. Blockers, frustrations, wins. - Next 10 min: Career Focus — One specific skill or goal we're tracking. Progress check, adjust plans. - Last 10 min: Strategic Context — Share context they might not have. Upcoming changes, cross-team dynamics.

Key Rules: - Never cancel. Reschedule if needed, but these are sacred. - Take notes and follow up. Nothing kills trust faster than forgotten action items. - Ask "What can I unblock for you?" every single time.

Building AI Tools That Actually Save Time

The difference between AI that impresses demos and AI that transforms workflows.

Read more

After building my SecondBrain system, I've learned what separates useful AI tools from tech demos:

Start With the Workflow, Not the Tech — I didn't build AI because it's cool. I built it because I was spending 3 hours/day on content creation. Now it's 30 minutes.

Automate the Boring Parts — AI shouldn't replace creativity. It should handle: formatting, platform adaptation, scheduling, and metadata. The human adds: insights, opinions, voice.

Measure Ruthlessly — My system tracks time-to-publish, engagement rates, and content consistency. If a feature doesn't improve metrics, it gets cut.

The goal isn't "using AI"—it's getting your time back.

More insights coming soon. Follow me on LinkedIn for updates.
