Data Processing Pipeline for Geospatial Data

A data pipeline that ingests data from public data sets in batch, IoT sensors, and drones in real-time. The pipeline automatically scales depending on incoming data. It processes incoming data automatically to store it in specialized data stores such as data warehouses and objects for reporting and machine learning.

Ground Segment Infrastructure for Cryptographic Satellites

https://docs.cryptosat.io/cryptosat/api-documentation
A back-end system to support end-to-end command operations to cryptography satellites. The architecture was built using a serverless architecture paradigm and supported public APIs for sending commands to the satellite for operations like storing private keys, signing messages with stored keys, signing tweets from satellites, etc. The system was responsible for managing registered users, tracking all their command operations, billing data, integrating with satellite command control systems, collecting and storing responses from the satellites, etc.

Network Configuration Management System

A RESTful API architecture to support automated network configuration of Cisco and Juniper routers to support new region builds for an enterprise. The system allowed developers to programmatically integrate network updates in their deployment pipelines using the APIs.
