Description of projects I worked on
Started off by making enhancements and documentation for existing tools for a couple of
weeks. As I got more comfortable with the team and what team did, I began undertaking
projects where I got to investigate a current problem and come up with a solution.
Details of Projects I worked on:
• Bug Fixes:
1. Audit log of JSON Web tokens using Serilogger with ELK stack.
This is a Auth-Microsoft service where in the logs of a web tokens are stored in
Elastic search.
When: SPRINT 1
2. Add all the Users to Systems Monitoring system:
At the time, the users who were notified of the system-status were addressed
as by pushing in the notification which would not notify a member of team.
The fix was to notify system-status to the Team Lead, Manager and the
Network Administrator
When: Sprint 2
• Projects
1. Developing a Portable Redis Cache Library which can be used to across
Company’s various Projects:
At the time, company’s monolith code where in there were multiple Projects
had different caching techniques. Ex: Mem-cache and Redis. I worked on
creating a single Portable Cache Library which can be used across all the
platforms as a Nugget Package. This will eventually be used to replace memed-
cache and bring uniformity.
When: Sprint 3 & 4
2. Automating CI-CD:
Developed software that can listen to Rocketchat (Company’s internal
chatroom) to automatically build applications in GitLab and Trigger deployment
in Octopus Deployment. Systems that interact with each other are: Hubot,
Rocketchat, GitLab, Octopus-Deployment. Technologies used: Powershell and
Coffeescript.
When: Sprint 5 & 6
Ended my Development work with documentation and code reviews.

Experience and How I applied my Course knowledge in my Internship
Spreetail provided me an excellent work culture & great people to work with. I stuck by
Company’s mantra: “Be Relentless Work Hard Learn. Adapt. Innovate Win Together” It was a
unique experience wherein I could leverage what knowledge I gained from the courses I took in
my First year of Graduate Studies.
Course CSE 5306:
Dr Jia Rao had various interesting Projects in Distributed systems which included Docker
configuration and environment as a bonus Project. With the help of learnings, I had in
his class I could understand how various Project Environments can be set up in a Docker.
I also had an opportunity to understand Docker working in Software Industry. I attend
my Mentors Tech talk on Docker to automate CI-CD in Omaha.
Course CSE 5311:
Algorithms was an integral part of all the development process. While I have not
explicitly created any new algorithm during my Internship, I have used many data
structures in that I used in class. Most of the different data Structures that I used were
in my first Project: that is Creation of Portable Redis Cache Library.
Course CSE 6324:
This was one of the best courses that helped me understand Agile Software
Development Life Cycle. Dr Khalili gave us an industry-like experience and having put
into practice was nothing less than deeper understand of Sprints. Code refactoring,
writing cleaner code etc helped me write better solutions.
Spreetail also gave an opportunity of understanding different technologies. There was a
flexibility to change the squads (Back-end to Front-end). As a part of trainings during Intern
onboarding I learnt various C# 6.0 features and understood the concepts like Dependency
Injection, Attributes, Reflection in .Net Framework.
