Hossain Khan

Endlessly impressed with the work Hossain has done in the Slack Android repo to improve our docsite and make contributing easy. Even down to setting up an auto-approving bot for any PR that _only_ updates docs.

Kudos to Hossain for including not one, not two, not three, not four, not five, not six, not seven, not eight, but NINE videos with a PR verifying a change. Be more like Hossain. Verify your changes with videos. Thanks for going the extra mile

Special Kudos to Hossain for going on the extra mile on the weekend to find issues and then report in such detail to our core capabilities mobile team and trying to fix the issue himself. Even though he couldn't solve it, he collaborated with us and didn't just throw it to us to do the work. This is what I love about working at Slack, its this collaboration and camaraderie.

I had the privilege of working with Hossain for 3 years at Slack on a team focused on developing the next generation of Slack's Platform—a broad, multi-year initiative. Hossain brings technical expertise, creativity, and contagious positivity to every project. Whenever we faced challenges outside our mobile domain, he tackled them head-on, eagerly learning and problem-solving across various areas. His proactive approach inspires others to step out of their comfort zones and tackle project challenges. During difficult moments with external stakeholders, Hossain was critical in helping us navigate and build both technical and interpersonal alignment. I truly hope we have the opportunity to work together again in the future!

I worked closely with him over the span of a year on a large scale concurrent platform and product development project. Hossain's technical skills, methodical approach and constant push to make the right technical/product decisions, has made him one of the best engineers I've had the pleasure of working with over the years. One of the things that set him apart from other great engineers was his kindness and infectiously positive attitude. It uplifted the team with release pressures were high, made him a sought after mentor and eased difficult conversations clients. He would be an asset on any team he joins and I hope we get a chance to work again in the future.

As product manager, I worked very closely with Hossain on a large scale, multi-faceted project for over a year. He has deep passion for the product he works on and is a dedicated and committed professional, always willing to go the extra mile to make sure the right architectural decisions are made in the interest of the client and project. In addition to being a solid engineer, he is a terrific leader. It is his empathetic leadership style that has been the driving force for our team and elevated him above his peers. He is both loved and revered for his ability to work closely with junior engineers and give them the right guidance and mentorship. He is equally comfortable working with clients / senior engineering leadership and leading the conversations to ensure that the right goals are achieved. Hossain is irreplaceable on any team he joins, and I can't wait for the opportunity to work on the next challenge with him again!

He is adaptable to different challenges and soaks up changing priorities without flinching. He made my job as a manager easier, and was a pleasure to work with.

Hossain was quick and expert in developing apps and working face to face with customers to gather and clarify requirements. Hossain worked well with other team members and even with difficult customers. He was always calm and respectful and was able to quickly develop new apps with complicated features, like eMBMS, LTE-B video and file delivery, 3rd party plug-ins for DRM and custom players, as well as work on other developers' code bases to fix bugs and extend new features. Hossain wrote very clean code which other developers readily accepted and leveraged. Hossain was a good multitasked and worked on multiple projects in parallel. I believe Hossain is a great individual contributor and has potential to be a team lead and manager. I'd work with Hossain again.
