I am a backend engineer working in the payments domain. I primarily work on Java, but I also dabble in Python for some mild analytical work. My proficiencies include - working with Kafka, Mysql, Cassandra, conceptualizing microservices, applying DDD principles while building services, instrumenting services to power monitoring and alerting, to name a few.

Developer

I'm a senior developer at a 100+ developer startup. I have worked extensively in the web domain and primarily in Python. My work involves designing and building end-to-end solutions that operate at scale.

I had previously worked at Klonio, a first of it's kind database version control system. I have extensively worked on MySQL & PostgreSQL. Other than that, I have experience on working with production level deployments of databases, multi-node clustered setups, defining relationships, designing tables, framing optimized queries, and the underlying indexes.

I have worked at startups that employ Django at their core. I have used various django packages/plugins as well in most of these projects. I am aware of framing well optimized queries, enforcing good design & putting Django's powerful ORM to good use among other things.

Among all the SQL databases I have worked with, MySQL is what I'm most comfortable with, in a production setup. I have worked  enough to know the impact of choice of table engines, or indexing algorithms, charset and collation related settings for locale support among other things.

My role at my current job is a mix between DevOps and developer. I have configured alarms, snapshots, security groups and worked on auto scaling groups. Basically, I can safely say I know my around the console.

Git would be the only SVCS I have ever used. I know my way around the cli, I have worked in collaborative environments to know the right workflows to employ. Git hooks, I've used extensively for continuous deployments. I am even familiar with hosting a private bare repository.

This is quite a vague yet vast category. I'm primarily a backend developer with some level of DevOps experience. I have worked on various kinds of setups. I am familiar with Debian, CentOS & RHEL based distros. I have worked on VPS's & bare-metal machines. I have a sufficient amount of networking know-how to tackle most issues.

MongoDB was the first database I familiarized myself with. I have dealt with tweaking collection & index based settings to good effect. I have used mongodb as part of a data processing pipeline. I am aware of the various use cases it has, apart from being just a "document-oriented store".

I have not worked in a pure DevOps role, but I can safely say that it was one of the many responsibilities in all of my jobs so far. I have configured proxies & load balancers, deployed thrift servers, restricted port access, tweaked TCP keepalives, identify when to use supervisor and when to run a cronjob, & setup centrallized application logs among other things.

My first webapp was built on flask. I use it extensively in most of my hobby projects. I'd say the documentation is extremely well written and with a little patience you should be set. But if that doesn't work out, I'm all ears! :)

I have used elasticsearch in 2 projects so far. The first one included setting up the nodes/cluster + zookeeper + creating the indices + defining the mappings & analyzers + seeding the data + writing queries. The other project was for application logging using the ELK stack - this mostly involved tweaking the server side configurations; garbage collectors can be really painful to deal with.

I apply DDD and SOLID principles while defining relevant abstractions to ensure proper coding hygiene while not compromising on extensibility. I also leverage async APIs where relevant, and am well versed with how to cope with scale.
