I'm Jacob Lefkowitz, a Computer Science sophomore at Northeastern University pursuing a Bachelor's in Computer Science with a Systems Concentration, continuing into a Master's in Software Engineering Systems through the 4+1 program.

I'm passionate about building robust backend infrastructure, diving deep into database internals, and architecting scalable systems. Currently exploring the intersection of systems programming and distributed computing while developing a strong foundation in software engineering principles.
