About Me

Hello World! I am @OsamaShabrez

Technical leader with 10+ years experience designing and delivering scalable web applications, leading teams, and mentoring engineers. Skilled in C#.NET, React, cloud infrastructure, and agile methodologies. Adept at bridging technical execution and team leadership to deliver high-quality solutions.

What I Do

  • I help engineering teams deliver business value with clarity, quality, and speed.
  • I lead through trust, technical excellence, and strong communication.
  • I turn complex requirements into scalable solutions that ship.

I’m an Engineering Manager and a Full-Stack Lead who blends hands-on technical leadership with a passion for team growth and product delivery. I guide engineers through architecture decisions, execution planning, and iterative development while ensuring everyone understands the why behind the work. My focus is on building a culture of ownership, collaboration, and continuous improvement that enables great engineering to thrive.

In my current role at a market-leading customer data science and analytics company, I connect product intent with execution, guiding teams to deliver technical solutions that advance customer and business objectives. I oversee engineering execution from requirements discovery and backlog refinement to code quality, deployment, and technical support.

People leadership is a core part of my work. I mentor engineers at different stages of their careers, create growth plans, provide feedback, and invest in their continued development. I believe in empowering teams, removing blockers, and creating space for individuals to do their best work.

Outside of work, I stay curious—sharpening my skills through technical exploration, leadership education, and learning across technology, business, and personal development.

If you’re interested in connecting, discussing engineering leadership, or exploring opportunities — let’s talk . I’m always open to meaningful conversations.
