In another project, I contributed to the development of an e-commerce application. My tasks involved refactoring the code to identify and fix critical phrasing errors. I also introduced new features such as generating the name of the product's color based on its name, handling cases such as black and white, black, and red. Optimizing queries was also part of my responsibilities, resulting in reduced request completion times.
Furthermore, I worked on developing solutions for data scraping, including bypassing bot protection systems like Cloudflare bot protection. From 0, I have developed a solution for automatically generating cover letters and resumes for vacancies based on candidate and vacancy data using LLM, with subsequent automatic responses to job postings. From 0 I have developed a system for accessing site content based on the client's location, screening unwanted visitors, and implementing bot protection. Additionally, I optimized page loading to achieve a Google PageSpeed score of 90+.
Looking for an interesting challenge project where I can improve my skills

Experienced dev/lead, love writing/desiging robust code. I do like coding as well as designing software on higher levels. I think the less meetings the better. For me it is important that code that i produce is easily readable and maintainable. My preferred area is backend using nodejs and nest js, but i’ve done quite some frontend as well. In my free time i’m trying to keep my self in good shape, playing video games. And no, i do not think that AI will take programing jobs.

Get in the project where everything is a mess with responsibilities with goal to set up processes to deliver high quality stable features in time and to make a team to work effective; work with people and their desires and motivation; a little of coding with a lot of code review; a huge amount of communication; direct responsibilities in architecture and codebase maintainability, making a decision in lack of context, technologies maintaining, features planning → decomposition → delegation. Great advantage is English is the only language for communication
