Specializing in PLC programming, industrial automation, and modern web solutions. Bridging the gap between software engineering and industrial technology.
I'm Jubayer Uddin Saad, an Automation & Software Engineer with a strong foundation in both computer science and industrial technology. My journey spans from writing clean, efficient code to programming PLCs that control real-world machinery on factory floors.
With a BSc in Computer Science & Engineering and a Diploma in Computer Technology, I bring a unique dual perspective — understanding both the logic of software systems and the physical demands of industrial automation environments.
My hands-on experience with Wecon & LS PLCs, Mitsubishi Servo Systems, and Blister Packing Machine automation has given me deep insight into how digital control systems interact with the physical world.
A curated set of tools, languages, and frameworks I use across software and industrial domains.
