Veriom

Lead Full Stack Engineer

Veriom • Freelance

Jul 2024 - Present2 yrs 1 mo

I work as part of the engineering team at Veriom, building and maintaining secure, scalable web applications using Ruby on Rails, React.js and JavaScript. My work involves writing clean, maintainable code and collaborating closely with other developers, product managers and designers to turn product requirements into reliable, high-performance features. I develop background jobs and asynchronous workers in Ruby on Rails to handle data-intensive tasks efficiently, and I use RSpec and other testing tools to ensure code quality and stability. I’ve also helped automate deployments through CI/CD pipelines to make releases smoother and more consistent. I’ve contributed to integrating AI-powered functionality to improve product personalization and user experience, and have worked on connecting the platform with more than twenty external services, including AWS, GitHub, GitLab, Bitbucket, Confluence and Notion. I participate regularly in code reviews to maintain quality and consistency across the team and help design modular components that fit within a microservices-based architecture.

WOSH

Founding Engineer

WOSH • Fulltime

Mar 2021 - Jun 20243 yrs 3 mos

I joined WOSH as the first engineer and played a key role in taking the product from an early-stage idea to a scalable production platform. Working closely with the CEO, I helped shape the product roadmap, define the technical direction, and lead development across the full stack. The platform was primarily built using Ruby on Rails, React, Redux, Google APIs, and AWS. I was responsible for key architecture and system design decisions, backend services and APIs, dynamic frontend experiences, Google API integrations, and selected Node.js microservices and utility scripts. I also created technical documentation and architecture diagrams, implemented unit, integration, and end-to-end testing, and managed deployment, reliability, and scaling across Heroku and AWS. Throughout the project, I worked closely with the business side to translate product requirements into technical solutions and continuously improve the platform as it grew.
