What I'm looking for

I am seeking a dynamic organization where I can apply my ERP, software development and data science skills to improve system reliability, drive data-driven decisions, and grow professionally while emphasizing clean code, user-focused design and minimal downtime.

I am a dedicated software developer with over three years of experience building and implementing robust ERP systems, RESTful APIs, and optimizing database performance. I have designed and delivered custom Dynamics 365 Business Central solutions, created AL extensions, led data migrations, and implemented modules for Finance, HR & Payroll, Pension, Investments, CRM and Property while emphasizing clean, reusable code and CI/CD practices.

I also bring data science and cloud experience—Python-based analysis, machine learning, data visualization, Azure and Google Cloud certifications—and a track record of user training, system support, and documentation. I seek roles where I can reduce downtime, improve system performance, and help organizations scale reliable, data-driven software solutions.
