Greece · More than 10 years of experience · Advanced/Fluent ·Published yesterday
I am based in Athens (GMT+3), where I live and work,
I have a Bachelor’s degree in Computer Science and over 20 years of experience in the field. I have worked on numerous projects involving complex systems and have a proven track record of delivering solutions.
My key strengths:
Strong knowledge of data structures, algorithms, and designing for performance.
Proficiency in Golang, C based languages, Java, SQL, and modern software design patterns.
Ability to work in an agile development environment.
Up until last July I have been working in Go for an OSS company, project RPort where I expanded my go experience - all my latest commits are on my GitHub page along with some small personal projects in various technologies.
Some examples of my achievements are:
- at the time (years 2006 - 2008) PostgreSQL didn’t have a good replication system that would allow us to parallelise servers to scale up the number of users per session or the overall queries/sec
Our Java App needed to scale, “to ramp up” at a specific time of the week, to reach an overall of ~90k visits per day so:
I separated the database, into 2 tiers, effectively dividing the data in a vertical way,
putting in one what was to be used in the users back office, aka settings and input database…
in the other layer, a fresh PRE-processed snapshot of the data to be queried in real time.
This approach allowed us to duplicate the second layer into n number of servers (data sharding) to achieve the needed performance increase. This was also rendered possible by a good architectural choice that a few were making at the time: to store binary data (images and video) inside the db as large objects.
- More recently I was asked to change a large set of ETL scripts: those were targeted at one version of the database and needed to be updated to run in the newer version while keeping the old one still active and running.
Instead of duplicating the whole thing, I created a small set of parsing shell scripts, basing it on standard comment lines; these scripts, together with the needed SQL changes, are now making it possible to regenerate the two sets of ETL’s from a common codebase.
- Since Docker was introduced, years ago, I integrated it into a range of projects: implementing application containerization at every stage of development and migrated several legacy products, reusing existing architecture and frameworks. I believe containers are truly the future for a modular and modern IT world, where sandboxing, real life testing scenarios and collaborative development are easy to implement.
I don't like very long meetings that go over the same thing 10 times.
I have designed and brought to life pretty complex app scenarios using more than one language or framework, and I am able to learn really fast - I am an open person looking to meet new people and work with them to develop exciting projects!
