I’m Shoaib, a Computer Science and Engineering graduate with a strong focus on professional video editing, particularly in podcast and long-form content. I specialize in transforming raw footage into structured, engaging, and platform-ready videos using DaVinci Resolve Studio. My work includes podcast video editing, documentary-style storytelling, YouTube content, and other long-form productions where clarity, pacing, and audience retention are critical.
A key strength I bring is color grading and footage refinement—working with raw clips to achieve consistent, cinematic visuals and mood-driven tones that elevate the overall narrative. I also focus heavily on audio editing and enhancement, ensuring clean dialogue, balanced levels, noise reduction, and a polished listening experience—especially important for podcasts and interview-based content.
I currently work with multi-camera setups, handling synchronization, angle switching, and structuring final outputs that feel natural and engaging. My editing approach emphasizes smooth transitions, intentional pacing, and clean visual flow, whether it’s a long podcast episode or a documentary-style piece.
In addition to editing, I bring a technical mindset as a developer and AI enthusiast, which helps me optimize workflows, handle complex edits efficiently, and maintain consistency across projects.
I’m committed to delivering high-quality work, clear communication, and a professional experience throughout every project. If you’re looking for someone who understands both the technical and storytelling aspects of podcast and long-form video production, I’d be glad to collaborate.
