I designed and implemented an in-house timeline system, which collects communications with our customers across all channels (chat, email, sms, phonecalls etc). Learned a lot, but also almost burned out closer to the end of the year. I was working remotely and mostly alone. Scope creep and lack of proper management has bitten me really hard. When I finally launched the app into production, I felt nothing but tiredness.

I still can't wrap my head around the React ecosystem. Front-end part was the most time consuming (probably because before this project I did only backend stuff). I enjoy react, but the whole game "build your own build system", "build your own framework" is beyond me. I hope the new year will bring more solutions like nextjs.
