Since November 2022, I have been operating as a freelance full-stack developer, technical lead, and IT consultant, collaborating with multiple U.S.-based startups and tech companies. In these roles, I have led the design and development of scalable web applications and SaaS platforms, utilizing technologies such as React, Next.js, Node.js, Python, and AWS. My responsibilities have encompassed architecting end-to-end solutions, implementing DevOps practices with Docker and Kubernetes (EKS), and establishing CI/CD pipelines (GitHub Actions) to enhance deployment efficiency. Additionally, I have provided strategic technical consulting, advising clients on best practices in software development, infrastructure, and technology stack selection to align with their business objectives.

In this role, I was responsible for designing the architecture and selecting the tools and frameworks to build an application from scratch. The application was highly complex, aimed at gathering performance and monitoring data from various sources, visualizing the overall status of different applications and environments, and tracking various types of incidents and alerts. I utilized clean architecture and hexagonal architecture principles to ensure a scalable and maintainable system design. I oversaw the entire lifecycle design, including the DevOps work for various pipelines according to the environment and the generation of Docker images. Some of the technologies used included Next.js with TypeScript for the frontend, and Node.js for creating APIs and various microservices. Additionally, I utilized AWS for all infrastructure services, ensuring scalability, reliability, and efficient resource management (ECS, EKS). My work ensured a robust and efficient system capable of handling high levels of complexity and delivering critical performance insights and monitoring capabilities.

In this role, I utilized technologies such as ReactJS, Next.js, RTK, Node.js, Backbone.js, and Micronaut for full-stack development, focusing on both frontend and backend solutions for web applications. I developed features and enhancements using JavaScript (TypeScript) and Java, delivering key functionalities for product releases, including ACH payments, 3D Secure, JSON-LD metadata, and translations. I helped new team members, supporting and collaborating with various squads on the design and implementation of new features, refactors, upgrades, and maintenance. Additionally, I participated in Performance and Instrumentation Working Groups, contributing to the enhancement of system performance and monitoring. My contributions ensured high-quality software delivery, team growth, and effective cross-team collaboration.

Design and implementation of CI & CD solutions for web and desktop applications. Developed and maintained automated pipelines to ensure seamless integration and delivery of software. Utilized Python scripting to automate various tasks and enhance the efficiency of the CI/CD processes. Employed Jenkins for orchestrating build, test, and deployment workflows, ensuring continuous improvement and reliable deployment of applications.

As the leader of the development team, I successfully spearheaded the release of diverse applications for supermarket chains, industrial factories, and other sectors. I was responsible for the maintenance and enhancement of customized ERP, payroll, logistics, and HR applications, along with developing interfaces with products such as SAP and Nodum. I also led the development of mobile applications for Android using the Flutter framework. Additionally, I designed and implemented CI/CD pipelines for web applications and services using Azure and Azure DevOps, ensuring efficient, reliable, and automated deployment processes.

Responsible for maintaining and developing .NET applications and SQL databases. Provided support to DevOps and Systems Administrators teams from a Software Engineering perspective, assisting in the definition and implementation of CI/CD processes.
