About

Professional summary

I am a software engineer with experience building web applications, REST APIs, cloud-based services, and automated testing solutions. I work primarily with Python, JavaScript, PHP, and modern frameworks including Django, Flask, Vue.js, React, and Laravel.

I have delivered backend and frontend integrations for e-commerce, payments, lending, and enterprise applications. My experience includes designing RESTful services, integrating third-party APIs, developing data-processing pipelines, and improving application performance and reliability.

I have also worked in software quality assurance, where I created automated test suites using Cypress, Geb, Spock, Selenium, and ServiceNow ATF. I focus on practical testing strategies, CI/CD integration, reusable test assets, and reducing manual regression effort.

As a solutions architect, I have led technical initiatives involving OCR adoption, event-driven architecture, automated loan processing, stakeholder communication, and evaluation of the business impact of technical decisions.

I am experienced with Azure, AWS, Docker, CI/CD, relational databases, Cosmos DB, virtual networking, Git-based workflows, and Agile delivery practices. I hold a BSc in Computer Science and an MSc in Open Informatics.
