I’m Mahesh, a Senior Data Engineer and Cloud/Data Architect with 13+ years building compliance-ready data platforms for large banks and fintechs. My focus: turning messy, multi-source data into governed, auditable, and cost-efficient analytics on AWS, Snowflake, and Databricks. Core specializations: AWS data lake/lakehouse (S3, Glue, EMR, Step Functions, Lambda, Lake Formation) Snowflake medallion modeling, row-level security, and performance tuning CTR/AML pipelines with automated data quality, lineage, and SLA monitoring Ab Initio → PySpark migrations, CI/CD, Terraform/IaC, Kafka streaming How I can help you: Architecture & Migration Review – share your current diagram or repo; I’ll provide a step-by-step modernization plan with trade-offs and a 30/60/90-day roadmap. ETL/Cost Tuning – identify bottlenecks (partitioning, parallelism, storage/layout), set lifecycle policies/tags, and target measurable SLA/cost goals. Governance & Compliance – implement DQ/lineage checks, audit trails, and regulator-ready controls. Career Coaching – resume/LinkedIn rewrite, mock interviews, and portfolio guidance for DE/DA roles. What to bring: a short problem statement, a sample dataset/schema (optional), and your success metrics (SLA, cost, throughput). You’ll leave with concrete next steps, sample code/snippets, and templates you can reuse. Sessions available in English (Telugu on request).
