How to Build a Startup for Remote 4G Drone Operations
udemy. com/course/lets-build-startup-for-remote-4g-drone-operations
In this Project/Course we are building a Cloud Application for Remote Drone Operations
from the grounds up - line by line - from 0 to the complete working solution.
Application main capabilities:
- on the web page user will be receiving very low latency live video stream from all of
the drones
- sharing video link with anyone anywhere in the world,
- seeing all of the drones on the interactive map,
- full manual control of each of your custom build DIY Drone
- control it from anywhere in the world,
- at any time to setup and activate missions on any of those drones while they are
flying.
Tech used:
- Java, to build a single file easy to deploy backend of our cloud platform that will
manage drone connections. This is a control station app in the form of a Uber Jar that can
be deployed either on a VPS or at the home server. This application exposes frontend on
the http port so the user, knowing VPS IP address can access app from anywhere and any
device. This app allows user to see on a map location of each of his drone, access their
video feed, talk from a drone loud speaker and manipulate each drone to perform
missions or FPV flights.
- Python, to build a drone control app that runs on a companion PC mounted on the
drone itself. On drone startup it automatically connects to the Java Control Station app
and constantly transmits drone telemetry data, video feed and also receives and executes
command coming from the Control Station.
- JavaScript, to write a single page application for our interactive user interface
We integrate all those applications to work together as a single cloud platform for remote
drone operations
By the end of this course, students not only learn a useful skills in Java, Python and
JavaScript, but most importantly, they see how all these technologies could work together
as one coherent distributed application that could easily have a real world usage.
Tech Stack:
Java / Python / JavaScript, Spring Boot, Sockets, Protobuf, Multi-threading, WebSockets,
MAVlink APIs, DroneKit framework, HTML/CSS, JQuery

My journey in programming spans from Java 8 to the latest version, Java 17.
In the database realm, I've navigated both relational (Postgres, MySql, SqlServer) and non-relational databases (Redis, MongoDB, Cassandra, RocksDB).
My tech toolkit includes Spring Boot, Spring Framework (Security, Data, MVC, Cloud, Config, Eureka, Feign), Hibernate, Jooq, Flyway, Liquibase, Mockito, and JUnit, etc.
On the DevOps front, I have experience with Docker, Rancher, and Kubernetes, Git, CodeCommit, and implemented CI/CD pipelines with CodeBuild and Jenkins.
My current project, which relies on event-based communication, includes 50+ microservices. During the last year, we've migrated all of the infrastructure from on-premises to AWS. My team is on the front lines of delivering new features to the customers. The last and biggest task we've implemented so far was to create a bunch of services (based on the SAGA approach) that communicate using the SNS/SQS to track some order states.
At this point, we're hight involved in the development of the service responsible for tracking shipments.
In my role, I handle various key responsibilities:
1) Developing Features: I create new features and enhance existing ones, actively contributing to the software's evolution.
2) Ensuring Code Quality: I make sure my code is reliable by thoroughly testing it with unit and integration tests.
3) Research and Innovation: I stay updated on new approaches and technologies, bringing fresh ideas to the team.
4) Collaborative Planning and Design: I actively participate in discussions and planning sessions, offering insights to shape new features in line with project goals.
5) Mentorship: I act as a mentor, sharing my knowledge and supporting the professional growth of team members.
In addition to my primary responsibilities, I also play a crucial role in the recruitment process by conducting interviews for potential team members.
My current goal is to continue my growth in the DevOps, and DevSecOps direction.
