Week 08/06/2017 - 09/24/2017 Last few weeks at work

  Backfilling those weeks from mid October 2017.

  I accepted an job offer in early August and sent my resignation to my team. It's been a great 4yr run, and I enjoyed every minute staying at work, especially in the past 15months since I started working on infrastructure. 

  It's a good fit for my skillset and I'm very interested in getting outside my comfort zone to learn new stuff.

  During these last 7 weeks I was not given much work, but I delivered a lot of things until my last day at work.

  I was supposed to do knowledge transfer but given my expertise in our server & infrastructure, it's a better use of my time to make a few last bits of contributions.

  It's kinda hard to recall exactly everything I did in these 7 weeks and I'll list the things I can remember and am proud of.

  A lot of time were actually spent on getting prepared for the new gig: it does require relocation so I need to deal with packing & moving. And I've spent a good amount of time chatting with people I enjoy seeing everyday. I'm very flattered to know that a lot of people at work enjoyed having me around and recognized my contribution to work. 

  On technical side, I was given permission to find my own tasks, here's what I remembered doing:

  I've released a change I had for connectivity handling on server by changing the protocol for newer clients, and significantly increased performance for disconnect & reconnect handling. 

  A few days were spent on investigating live issues that have been existing in our product for years and our players hated. I was able to find the root cause and apply a proper fix to get rid of those issues completely. Hopefully after all these fixes I've done for the past few years, the core part of our server has become rock-solid. 

  There is one issue I fixed on the day before my last day, which causes game to stuck indefinitely. I'm proud of myself to hypothesize a theory within a few hours of investigation and prepared a fix. A few weeks after I left work, people at work told me that one fix was rolled out and dropped the stuck game metric by close to 90%. 

  Profiled performance of a system I wrote a while ago and surprised to see it can't be easily improved. 

  I've got bad memory and I should write things down more often instead backfilling. I'll be more diligent about this blog.
