What I'm looking for

I’m looking to lead end-to-end data platform architecture on AWS—owning data governance, building scalable ETL pipelines, and delivering reliable analytics and reporting that turn business needs into measurable outcomes.

I’m a Senior Data Engineer and Data Architect with 6 years of experience across Data Science, Data Engineering, and Data Architecture roles. I specialize in designing and building scalable data platforms from scratch, defining end-to-end data architectures, and delivering analytics and reporting solutions on AWS.

Most recently, as Data Team Lead at Paynopain, I’m leading the design and implementation of the company’s entire data platform—defining the global AWS-based data architecture, building a centralized AWS Data Lake with data governance and fine-grained access control via Lake Formation, and developing scalable ETL pipelines. Earlier roles strengthened my foundation in data quality, analytics pipelines, and dashboards using AWS services (including Glue, Lambda, S3, and Athena), Python/SQL, and BI tools like QuickSight, Power BI, Tableau, and QlikSense.
