IoT-ware is an IoT system that communicates to and orchestrates IoT devices, integrating software tools for design, development, engineering, commissioning, operation, and optimization steps.

I acted as a full-stack developer and team leader in designing and implementing IoT system deployment processes laid out by academic research.

A Java Spring framework-based application for consolidating and managing food aggregators. Import public food menus from food aggregators and manage them in a normalized entity model for efficient and easy access by restaurants.

I worked on the command and control of air defense assets such as weapons, sensors, command and control centers, and integration units. I contributed to the combined air picture with correlated data from sensors and NATO air track sources. The communication layer uses TCP/IP and X.25 protocols.

Development of a race direction system front-end web application for evaluating incidents in the time car race game Assetto Corsa.

The 3D rendering of race track, onboard view from inside the race cars, play, pause, and seek timeline features were done with TypeScript, React, Three.js, MUI, HTML, CSS, and GraphQL. The back-end API implementation of the race direction system was done using GraphQL, AWS, and Hasura.

Custom CNC machine controller C#.NET desktop program implementation for a company that prints on t-shirts using their proprietary CNC machine. The Arduino software communicates with the machine through RS-232 serial port. (C#.NET, GRBL interface, Arduino)

A desktop application that runs on MS Windows that can encrypt and decrypt files when dropped on top of the program's main window. Automatically renames the encrypted and decrypted file after operation.

A crypto-wallet mobile application implemented using React Native that runs on iOS and Android. Integrates to Bitcoin and Ethereum networks, tested using Ganache blockchain simulator. It can create a mnemonic phrase for the user, generate receive addresses for networks, and displays balances for favorite ERC-20 tokens.

Software for receiving commands through a Raspberry Pi's UART
interface and plays, pauses, or stops playback of video files inside the Raspberry Pi based on the command received. It is implemented in Python and runs on Ubuntu Mate.

An application suite for application store management systems for industrial devices. The front-end web application is implemented using React and MaterialUI. Application store is configured using a private custom Docker Registry and Docker Containerization API. Authentication into Docker Registry is done using Docker Authentication Server (github.com/cesanta/docker_auth).

Worked on implementing microservices running on a desktop computer and embedded software running on an Arduino microcontroller board.
I developed automation of factory crane movement, discovery and avoidance of objects on the factory floor, and an optimization algorithm for material placement.

I provided translation services on Kubernetes cluster using jobs and cronjobs. I worked on implementing an API gateway (dispatcher) for requests for spinning up Kubernetes job for the bi-directional transfer of translations for locales on the IBM Kubernetes cluster.
My duties were the following:
• Storing completed translations in Amazon S3 compatible IBM Cloud Object Storage
• Accessing Contentful (headless CMS) content preview, delivery, and management APIs for content retrieval
• Implementating Contentful front-end application for displaying translation status on the Contentful dashboard

A software catalog system for managing software installed on various nodes across an organization that I developed for Deskcenter AG using ASP.NET Core, MediatR, CQRS, the Unit of Work pattern, and Entity Framework.

Developed and maintained a comprehensive legislation and bill management system for the State of Colorado, actively used by General Assembly members to streamline legislative processes. Designed and implemented scalable back-end RESTful APIs with Java Spring MVC, supported by robust unit tests using JUnit and Mockito. Built a dynamic, user-friendly front end with React, Material-UI, AG Grid, and modern state management techniques using Redux and Context API. Integrated LDAP for secure authentication, role-based access control, and optimized database operations with MS SQL Server. Delivered a high-impact solution by leveraging React Hooks, adhering to best practices, and collaborating with cross-functional teams to meet legislative requirements effectively.
