What I'm looking for

I’m seeking a Backend Developer role where I can build and maintain scalable, secure web applications and RESTful APIs, optimize databases and system performance, and continue learning while contributing to reliable solutions and business growth.

At Innover Digital, I developed, enhanced, and maintained PHP-based web applications, working on bug fixes, code optimization, and system performance. I also wrote and optimized PostgreSQL queries.

At Eleviant Tech (CTG Group), I developed and maintained a CRM application using PHP and Laravel. I implemented a PubNub chat system and worked on an AI-powered Call Summary feature for transcription, summaries, categorization, and translation options.

I also worked on chatbot features using Python and NLTK, contributing NLP improvements and performance enhancements. Across projects including Contact Centric, Renault Planned Ordering System, My Renault, and IT Track, I worked on application support, bug fixes, and backend development.

For Contact Centric, I implemented Laravel REST APIs for an Angular frontend, integrated PubNub chat and a third-party CRM, and deployed the application on Linux. I also worked with AWS services and contributed to service migration.
