Spain · 9 years of experience · Advanced/Fluent ·Published 29 April
For the past three years, my responsibilities have included:
Writing simple, reliable, maintainable and testable code
Organizing team work: Delegating and distributing tasks, as well as resolving technical blockers.
Leading teams and conducting interviews, including pre-sales activities.
Communicating with architects, product owners, and other teams to create technical stories, ensuring the timely delivery of valuable features to production.
Creating proof of concepts.
I've actively participated in designing and implementing startup that being sold for 85$ mil.
I have redesigned systems multiple times to enhance their efficiency, implementing various optimizations that resulted in cost savings for the companies. For example:
Relocated image and document generation to the client side, reducing server CPU/GPU usage by 70%.
Downsized a system that heavily depended on AWS infrastructure. By migrating several services to on-premises solutions, we were able to reduce server costs by threefold.

Further development/wish:
-------
My aspirations for further development: Ideally, I would like to participate in creating a large-scale project from scratch, utilizing cutting-edge technologies such as Next.js or the upcoming React 19. Given my experience in both large and small teams, on long-lived projects, and in initiating projects from scratch, these factors are not critical for me; both scenarios are suitable.
Additionally, I would like to be involved in backend development. I would be thrilled to contribute to a cool public project that can be used by many people and provides significant benefits (for example, in education, tourism, or history).
- Successful rewriting of extensive and complex legacy components from class-based to functional, code decomposition, adherence to DRY principles
- Addressing critical bugs in asynchronous web requests that occurred irregularly and required thorough investigation to identify the root cause, develop a corrective action plan, and implement the necessary fixes
- Optimization and refinement of complex GraphQL queries to retrieve only the data directly utilized by the specific case/component
- Optimizing and fixing file uploads in request forms
Nissan AOP:
- Successful creation of a project from scratch
- Accomplishing over 95% of tasks on time without delays
- Full test coverage of the entire application, including the backend part
- Successful deployment of an application on AWS with subsequent configuration, followed by a successful deployment into the client's environment
- UAT (User Acceptance Testing) was successfully completed after delivering the product to the client and required only minor adjustments or clarifications, with no critical errors or issues
- All functionality that was not discussed during the planning stage but emerged as client wishes during development was implemented or modified as required during the process
Nemours (parallelly helped while working on Nissan AOP):
- In a short period of time, I assisted the core development team in fixing critical errors related to working with multiple forms, asynchronous operations, styling, error processing, and error handling, among other areas.
I am also open to a hybrid work schedule. While I already have experience in the development world, it would be great to have colleagues of varying levels of knowledge so that I can share experiences, seek advice, or receive recommendations.
I would prefer not to work in the gambling industry.
