ABOUT

Glad to work any technology which involves L&D based on client/workplace requirements. I have been working on multiple roles starting from Developer to Management & Operations. My current role is a Technology lead which involves day to day hands on development on Go Lang & Java based projects. Also involved in team mentoring and training the rest of the team with cutting edge technologies. I would Rate myself as a Back-end Developer, who is good in dev ops and able to work on Front end. Experienced in Managing/Leading teams, Project Estimation, Scrum/Agile and Client Facing scenarios. Well versed in logics, basics of programming and ready to code, independent of platforms. Happy to spend lot of time with machines and love to write codes night and day. Able to learn new languages and ready to work in significant contribution to the organization. Eager to meet challenges and usually adopt to the culture of the surroundings to fit in. Happy to learn new methodologies and looking for better functionality at all times. I just believe in the fact that learning all sorts of code never means to use them all the time, it becomes an enjoyable hobby to learn, adopt, test and implement new platforms & their logics at some point of time is of great use.

Internal SQLite/Realm Database for book contents

Night Mode (less light for cockpits at night) using a toggle on the main screen, Search (from SQLite

UI.

• The database is a PostgreSQL instance in RDS.

However, it is not a traditional RDBMS model.

Instead, it is a hybrid between key / value store and traditional SQL. First, our PostgreSQL uses the

hstore module to provide key / value store within

the database.

• contractor -> subcontractor, service provider,

service professional (if they are a part of the

contractor's company), themselves

• subcontractor -> service professional (if they are a part of the subcontractor's company), themselves

Scott IPC Plotting Chart (07/2018 – 01/2019)

• The Plotting Chart utilizes the ARINC

(Aeronautical Information Regulation and

Control) NAV Database, provided by ScottIPC.

• The ARINC NAV Database needs to be parsed

to upload and provide only that data from

within the defined areas outside of the

polygons that are provided. This document

delineates the polygons that encircle

landmasses that are NOT to be used from the

ARINC database. All the areas outside the

polygons delineated in the document are

required.

• The ARINC NAV database needs to be updated

on a published cycle. The database can be

uploaded to portal, processed to extract the

specific records required for PC support, which

will result in a internal version of a

'PC_database' for all App user's to import.

Note: To minimize the amount of data

transferred to the App, only the delta changes

to the 'PC_database' will be imported versus a

complete database update.

• The portal will provide a function that will

allow a selected set of iPads to be configured

for a QA test of the ARINC database import

and creation of a 'PC_database'. This function

will allow for testing prior to general App user

availability in a production environment.

• App will have a hamburger menu item to

display the version of ARINC NAV database

that was utilized to create the internal

'PC_database' and currently in use by the App

Tools Used – Go Lang with PostgreSQL

deployed on AWS with Docker containers,

ARINC DB.

Tools Used – Go Lang with PostgreSQL deployed on

AWS with Docker containers.
