Contributing to the completion of a large microservice-based application for a global automobile manufacturer. This platform integrates connected vehicles with the manufacturer’s systems, enabling remote commands, map updates, and data synchronization. Among other things, I worked on:

• Handling secure data ingestion for vehicles, processing encrypted zip files to enable certificate-based secure communication
• Synchronizing databases across multiple regions to maintain consistency and availability
• Managing synchronous and asynchronous communication for data flow coordination between services

Coordinating the team to deliver the applications that the customer needs using Agile methodologies, doing my best to get some coding done as well during the day.

The main projects I have been focusing on are:

• Delivering a big microservices project for a telecommunications company that handles several business flows, integrating new microservices and platform with their existing ecosystem
• A platform built and designed from scratch by our team which put in contact companies that wanted to do POSM/marketing with different freelancers who could accept and work on such “missions”

Working on different applications either in a team or by myself as a full-stack developer:

• platform for a telecommunications company that handles different business flows using Java, Spring, Angular, on a microservices architecture
• facility management platform that handles ticketing cases, written in Kotlin, Spring, Angular
• oauth2 server and endpoints to allow clients to more easily integrate with the romanian banks that have exposed their APIs based on the the PSD2 standard
• an app for the government, which managed city hall’s organization flows and helped schools receive fruits/vegetables by different producer/distributors from the county

As a Dev Engineer in ING Tech I have worked in two different departments on different projects:

• Wholesale Banking department - built a REST API that was used to expose an application which was used for supply chain finance logic and started rewriting parts of that application from Legacy code to Java/Spring
• Security department - build APIs (REST, TCP, JMS) as a middle layer in a fraud detection flow. Also built components as means of authentication/authorization for ING Group’s several application as part of the main security tribe/flows
