About Me
My Journey
Hello! I'm Bilal, a passionate software engineer who thrives on building scalable systems that make a real impact. My journey began at Brown University, where I focused on AI/ML and developed a deep appreciation for elegant, efficient solutions.
Over the past 5+ years, I've had the privilege of working with industry-leading companies like Nextdoor, Apple, and Adobe, where I've led initiatives that directly impacted millions of users and drove significant business growth.
When I'm not coding, you'll find me exploring the latest in distributed systems architecture, mentoring aspiring engineers, or experimenting with emerging technologies. I believe in continuous learning and sharing knowledge with the community.
Core Values & Philosophy
Code Quality First
I believe in writing clean, maintainable code that stands the test of time and scale.
Collaborative Leadership
Great products are built by great teams. I focus on empowering others to do their best work.
Continuous Learning
Technology evolves rapidly. I stay curious and adapt to new challenges and opportunities.
