About me
I am a BI Developer with over 6 years of experience specializing in creating end-to-end data-driven solutions across industrial, mining, and energy sectors. My expertise lies in building insightful dashboards, automating reporting pipelines, and uncovering actionable business insights using tools such as Power BI, SQL, and Python. I have worked extensively on both frontend aspects like visualization, UX, and business logic, as well as backend components including data modeling, queries, and integrations across multiple BI platforms including Power BI, Tableau, Fine BI, and Oracle Analytics Server.
Throughout my career, I have delivered more than 50 dashboards for C-level stakeholders and successfully reduced manual reporting time by up to 50% through automation. I have also migrated BI logic and models across more than four BI platforms, ensuring seamless transitions and optimized performance. Beyond traditional BI development, I have hands-on experience creating custom visualizations using Vega-Lite and D3-based specifications, developing Python API connectors for custom data sources, and managing database administration and optimization for PostgreSQL, MySQL, and MS SQL.
I am also experienced in working with AWS cloud infrastructure, including EC2, S3, and RDS, to host and automate BI solutions. As a freelance BI consultant, I assist clients globally in building, optimizing, and troubleshooting their BI systems by combining strong business acumen with technical implementation to deliver clear, scalable, and visually engaging analytics.
I am passionate about data, creative problem-solving, and transforming complex data into clear insights. I am open to full-time or freelance remote opportunities and eager to connect with professionals who value data-driven decision making and innovative BI solutions.
Feel free to reach out or DM me to discuss how I can help your organization leverage data for better business outcomes.
