Throughout my career I've been focused on developing 0-shot information extraction technologies, including Named Entity Recognition, Relation Extraction, and Text Classification. Apart from that I created a unique approach for "table extraction": the model that converts textual sources into structured tabular databases by extracting relational data. Example: Company X secures $25m series C funding. Fund Y led the round among additional investors W and Z --> Company - Company X | round - series C | amount - $25m | lead investor - Fund Y | additional investors - W, Z. 0-shot learning enables any values collection just by defining them in Natural Language. All technologies surpass known competitors, like GPT4, IBM, John Snow labs, and others.

Who am I? I am a seasoned Java developer with 13+ years of experience and 20k+ completed hours of work including 5+ years of team leader experience. What can we do together? I'm here to assist you with your Java project. Whether it's: * a regular developer work: - resolve your business problems with Java software, - translate your business requirement into technical and implement it, - find and resolve glitches, - write a new small project from scratch; * a Java lead work: - review your architecture and code and provide recommendations for improvement based on your goals, - make a plan to transfer your app from the current state to a better one, - lead the development with quality, delivery, and cost management, - help you achieve a product that aligns with your vision. I have solid experience with software development from planning a feature to the deployment strategy, from writing a code to A/B testing implementation. Why can I do it? Since 2011, I have worked as a Java specialist for various outsourcing companies in Ukraine. I have assisted world industry leaders in enhancing their products across several domains, including information technology and services, automotive navigation systems, banking and finance, real estate, and outsourcing and consulting. For the past five years, I have been leading teams consisting of 2 to 12 people. I have extensive experience with Java, Spring/Spring Boot, REST, relational and NoSQL databases, message brokers, microservices architecture, AWS, Docker, k8s, etc. I also have experience with Scala, Groovy, JavaScript, TypeScript, and React. What I'm not ready to do: * CSS - I can not center a div (well, I can, but it hurts) * DB design - I can write an SQL query, but I have no experience designing a complex database from scratch that is more intricate than a Pet Clinic. Therefore, I cannot accept payment for that. Upwork: I'm just starting to work on this platform, so I'm strongly motivated to get new clients here and ready to negotiate. Please message me to work together to make your business even more successful! Let's have a call or chat and discuss possibilities!
