As a skilled Software Engineer specializing in IT startup environments, I have 5 years of experience in designing and developing innovative software solutions using technologies such as JavaScript, Python, Java, C++, C#, Node.js, React, MongoDB, and Docker. I am currently finishing Master of Science in Algorithmics at the University of Konstanz. Here, I am developing a novel method for Approximate Nearest Neighbor Search using skip graphs, leveraging Java for implementation. My professional trajectory is distinguished by my roles in managing and executing complex projects that integrate advanced technologies and Agile methodologies.🌟 Top Three Achievements1️⃣ Modernization of John Deere's Financial SystemsI led the modernization of John Deere's financial systems, transitioning from legacy COBOL applications to scalable microservices optimized for AWS cloud deployment. This project replaced outdated SAS reports with advanced data processing modules using microservices developed in Node.js with TypeScript and Java with Spring Boot. I implemented indexing and pagination for faster SQL queries, significantly enhancing processing speed and data accuracy while ensuring compliance with modern data standards. Leveraging various AWS cloud services such as EC2, ECS, Lambda, SNS, and ELB, I focused on scalability, maintainability, and cost optimization. This initiative highlighted my technical expertise and ability to lead critical technological upgrades in a cloud-based environment.2️⃣Leadership in Development and Integration of the Kovalent PlatformAt American Technology Consulting, I led the development of the Kovalent platform, an integrtion platform that enhances middleware solutions for various HRIS clients including Hibob and Shopify. My leadership in using technologies like Node.js, Express, and MongoDB was crucial in streamlining operations and improving data management. This achievement not only optimized client service but also demonstrated my ability to manage large-scale software development projects effectively. 3️⃣ Best performer award: VymoAt Vymo, I was honored with the Best Performer award for my work on the Goals microservice with the client HDFC. This service tracked employee performance on an individual level and maintained organizational targets, which could be set monthly, quarterly, and yearly. Developed using Node.js and TypeScript, I also leveraged Kafka message queues for implementation. This module not only boosted existing business performance but also attracted new client contracts.
