On the 8th of March '18, I have produced my first block^20504909 on the STEEM blockchain. Almost one year has passed since I produced that block.

It was a great year. I have worked on and contributed to countless STEEM related projects and am involved in lots of STEEM communities and -most importantly- used Steem as my primary online social network.

Witness infrastructure

I run three dedicated servers to support the STEEM network:

Name	Properties
Primary Witness	i7-6700 Quad-Core 64 GB DDR4 2x2 TB SATA
Secondary Witness	i7-6700 Quad-Core 64 GB DDR4 2x2 TB SATA
Hivemind	i7-6700 Quad-Core 32 GB DDR4 2x500 GB SATA SSD

In addition, a script on a small virtual server constantly monitors my primary witness' status and failover to a backup server if a block miss occurs.

Even though I roughly produce 1 block every 45 minutes, it is important to keep the block misses as low as possible.

Projects

Here is a quick highlight of what I have contributed during the last months:

I have founded and developed dpoll.xyz. dPoll is the only running polling app which operates on a blockchain. It's currently ranked at #6 on steemapps. The dPoll platform generated around 5400~ blockchain transactions in the last 7 days.
I have created Tower. A REST interface to Hivemind. It's the first project that enables access to the Hivemind database without owning a Hivemind instance.
I have introduced the first public Hivemind node.
I distribute daily database snapshots of Hivemind.
I have developed Heisenberg which is a Python framework to play Drugwars.
I have developed Lightsteem. A Python3.6+ framework to interact with the STEEM blockchain.
I have developed infestor. A project that offers accounts for free. I have given away more than 150 accounts with this tool to the community.
I have developed transmitter. A Python3.6+ witness update/feed update tool. (Supports broadcasting with signing keys.)
I have developed steemconnect-python-client. Many applications use it to develop STEEM applications.
I have developed tagbot. A community curation bot based on tags. Lots of communities still use it.
I have developed instasteem. A CLI tool to cross-post your instagram posts to your STEEM profile.
I have developed dcom. A discord for STEEM communities. @sndbox, and @dolphincouncil projects use it.

And more... I don't want to bore you with all of them. :).

Contributions

I have contributed to steemdocs project.
I have contributed to busy.org.

Community Involvements

I helped @sndbox as a curator for organized contests. I Also maintain the main discord bot which handles registration and curation.
I develop and maintain an automated voting bot for @creativecrypto.
I review submissions in the development category for @utopian-io.

Future plans

I will continue developing and maintaining my open source projects and tools.
I will continue to support applications and communities with my skills and expertise.
I plan to have hands-on experience in the blockchain's core part. At least the ability to review the changesets and hard forks with a better understanding. I can already understand the code, however, I cannot say that I am %100 comfortable with it.
I will run a full RPC node as soon as producer rewards cover the costs. (It requires a top20 spot to support it financially at the moment.)
