With over 7 years of hands-on corporate experience, I have helped my previous clients to Migrate their Monolithic Java Applications to a Distributed Microservices System. I also specialize in helping teams become more productive and efficient by improving their builds time, decreasing deployment times and helping to increase faster production shipments. I am incredibly fast at crafting tailored solutions to your technical problems, not just for the short term but for the long term. I have honed my skills not just in coding but also in collaborating with stakeholders, to understand the business needs and translating them into revenue producing products. My expertise resolves around Java, but it extends beyond Spring Boot to include various Java libraries, NodeJS, and frontend frameworks like JQuery, React, and VueJS. I am confident that I can make a significant contribution to your team without needing extensive supervision or training. Let's connect and discuss how I can add value to your organization.
