Over the past 6.5 years, I have been luck enough to work on various projects using a lot of modern technology, here I want to take a step back, dump all the knowledge I have learnt, and see what is the next adventure for me.

Programming Languages: C/C++, Golang, python, javascript

Databases: Mysql, maria DB, time series DB (influxDb), noSql DB (Google Datastore, MondoDb)

I even wrote my own DB: DatabaseBackendEngine

Distributed System: Implemented Raft (KVRaftDB). Understand CAP theorem. Distributed tracing, distributed transaction, serialization, 2 phase commit, master/slave replication, DB replication, DB partition, Sharding, Load Balancing.

Cache: Redis. Cache methods: lazy write, write through, read through.

Lock: distributed locks, semaphore, mutex

Briefly touched Frontend: Vue.js, Backbone.js, html/css

Testing: unittest with python, stress testing for large scaleable applications

Monitoring: graphite, grafana, prometheus, datadog. Use statsDB to send data. Can also use pub/sub system to fetch from datasource.

Leadership: mentoring junior engineer, code reviews, design reviews.

Interests: System design, Architectural design, Distributed system

No interest: Frontend, code monkey, fix other people’s bug from daily duty.

I have very strong will, and love all things in distributed system. I never settle down and always challenge myself to a different level.
