His role as an infrastructure solution architect and systems design expert was instrumental in the successful execution of our technology initiatives. Farhan’s ability to lead and manage teams of diverse backgrounds and skill levels was particularly impressive. He consistently fostered a collaborative and inclusive work environment, where individuals from various domains felt valued and empowered to contribute their unique perspectives.

One of motivation factors for me to continue my job at Banglalink is learning from my colleagues. Farhan Bhai is one of them I learn something new when we talk and work on any IT Infrastructure related issues and application scaling. He is the most knowledgeable Sysadmin I’ve ever seen as of now. An sysadmin with strong programming background what can do Farhan Bhai is exemplary for Bangladeshi Linux professionals. Not only he is technically sound but also he is an excellent mentor and leader for his team. He infused continuous learning culture within server, storage and backup team he is managing here at Banglalink. Finally, I thank him for continuously helping me and my team to run and maintain 50+ node Hadoop cluster to meet analytical needs of different departments.
