During the past 17 years, I've developed both Internet sites and Intranet/enterprise systems - from news portals to dating sites to ISP billing systems to HVAC controllers to Logistics Management systems, and more. My core skills are Java/J2EE, with experience in both commercial (Orion, WebSphere) and open-source (JBoss, Tomcat, Glassfish) application servers and most popular databases (MySQL, Oracle, MS SQL Server, Sybase, etc). I have a good understanding of modern Web technologies and several years of experience developing Web applications using Vaadin Framework, but my primary focus and my primary strength are backend technology stacks. I have experience with developing highly scalable clustered systems supporting up to 8000 concurrent online users. I'm familiar with in-memory data grids (like Hazelcast), NoSQL databases (like AWS DynamoDB and MongoDB) and other high-load/high-availability technologies. I have extensive experience developing applications that run on Amazon Web Services cloud computing platform. I'm familiar with all phases of software development - from coming up with functional requirements to design, development and testing/support. I've been leading teams of up to 10 developers, as well as managing projects lasting up to 5 years. I have good working knowledge of Scrum agile software development methodology. I'm a long-time open-source proponent. Over the years, I've contributed to several open-source research projects, such as Freenet and I2P. I develop some of my own open-source projects as a hobby in my spare time. I hold a position of research fellow at the Department of Computer Science, Lomonosov Moscow State University (my primary scientific interests are small-world peer-to-peer networks, natural language processing and application configuration management), and for this reason I, unfortunately, can't accept jobs that absolutely require more than 30 work hours per week. **I'm looking for opportunities to work on your Web or internal project using Java/J2EE technology stack, as well as to manage a software/Web development project.**

Hi! I want to work with you on finding solutions to your IT problems. Mainly working with PHP back-end and database design, but can help you with software architecture and problem solving in general. Prefer using Symfony framework to meet the project needs, but can easily work with other frameworks and techs as well. After all tools are just that, tools, which are there to help us in reaching our goals. Sometimes finding the right tool for the job can be bigger part of the job itself. Skills: * Languages PHP, JS, C# * OOP and design patterns using popular coding principles like DRY and SOLID * Database design * Code testing, both Unit and Functional * Striving for clean and documented code * Experience with SOAP and REST interfaces * Versioning systems, GIT, SVN and popular flows * Queues (AMQP) * Experience with server configurations, Apache and Ngnix on both Windows and Linux (multi distros) * Experience with hosting services such as AWS, DigitalOcean, Linode and more Of course, problem solving and coding aren't the only part of programmers job, there are also unavoidable meetings, workflow optimizations, team syncing and plethora of other stuff programmers usually would like to skip through. While these can be mentally cumbersome, they shouldn't. Both employees and employer should work on maintaining healthy professional relationship and be open to giving and taking constructive criticism as well as support to each-other. So good, healthy working environment is, in my opinion, maybe the most important thing, which gives stable legs for everything else.

In the realm of Microservices Design and Implementation, I specialize in transitioning monolithic applications to scalable microservices using Laravel and PHP. With a focus on aligning solutions to your business requirements, resources, and existing architecture (if applicable), I offer a comprehensive approach to modernizing your systems. Microservices are carefully evaluated to determine if they are the right fit for your needs, ensuring the design and implementation process supports optimal scalability and maintainability. Assistance can be provided to review, implement, or design microservices, whether starting from an existing architecture or building from scratch. Additionally, you will benefit from PCI DSS expertise, ensuring that application development adheres to the highest security standards. This includes not only technical implementations but also comprehensive documentation and team leadership, guiding development teams through best security practices. Your systems will evolve into a modern architecture while maintaining compliance with industry standards. I also have experience in developing and implementing AI/ML (NLP) solutions, including creating and training transformer-based models, optimizing datasets, and working on Retrieval-Augmented Generation (RAG) systems using Python and the Haystack framework. Skills: • Microservices Design and Implementation • Laravel • PHP • Docker • Kubernetes • Apache Kafka • RESTful APIs • SQL & NoSQL Databases • PCI DSS Compliance (Best practices from documentation to implementation) • Artificial Intelligence (AI) Model Development and Deployment • Retrieval-Augmented Generation (RAG) Systems Hourly Rate: $80 - $150 USD per hour Project-Based Pricing If clients prefer project-based pricing, consider structuring it depending on the scope of the work: - Small/Mid-size projects (reviewing or assisting with microservices architecture): $5,000 - $10,000 USD - Large projects (full microservices implementation, PCI DSS review, or comprehensive audit): $15,000 - $30,000 USD or more, depending on the project duration and complexity. Considerations: • Higher-end pricing would apply to businesses that need a complete transformation with high compliance standards (e.g., fintech, healthcare). • Lower-end pricing could be used for startups or smaller companies that need a quick consultation or review.
