As a customer-centric professional, I prioritize acknowledging and addressing customer needs above all else. With extensive experience in project delivery, project management, and customer success, I consistently deliver successful projects while ensuring customer satisfaction.
• End-to-end data & BI architecture (from scratch → scale): Started with a greenfield POC and built the platform from zero, proving value quickly and then scaling it into a production-grade analytics stack (Medallion Bronze/Silver/Gold) across Microsoft Fabric + OneLake + Power BI, aligned to Marketing, Finance, and Sales outcomes. • POC-to-Production approach: Delivered an initial “thin slice” (1–2 critical KPIs + minimal pipelines + first semantic model), then expanded into governed data products, broader coverage, and operational excellence without rewriting everything. • Layered design with clear contracts: Bronze: ingestion + raw history retained for traceability Silver: standardized schemas, enrichment, business logic, deduplication Gold: curated marts/aggregations optimized for Direct Lake and reporting performance • Performance-first architecture: Moved expensive logic upstream into Spark/Delta and introduced daily/monthly aggregated tables to keep Direct Lake models fast while preserving metric consistency. • Data product mindset: Treated gold outputs as owned data products (defined consumers, KPI sign-off, SLAs, quality gates) so teams reuse the same trusted definitions across dashboards. • Governance & reliability built-in: Added naming standards, lineage-ready structure + documentation, automated QA checks and alerting (staleness, duplicates, referential integrity, cross-table reconciliation) to prevent silent drift. • Deployment & safety: Designed for DEV/TEST/PROD separation with Git versioning / CI-CD patterns to enable repeatable deployments and reduce overwrite risk.
• End-to-end data & BI architecture: Introduced and scaled a modern analytics platform (Medallion-style Bronze/Silver/Gold) across Microsoft Fabric/OneLake + Power BI, aligning data products with business outcomes (Marketing/Finance/Sales). • Lifecycle ownership (build → run): Led initiatives from discovery and KPI definition through implementation, release, and ongoing operations—treating dashboards and datasets as production products with SLAs. • Data engineering in Fabric: Built PySpark/Delta pipelines (incremental loads, merges, shortcuts, partitioning) to deliver trusted fact/dimension layers and reusable marts for high-volume reporting. • Semantic model excellence (Direct Lake): Designed and optimized Power BI semantic models for performance and scale (aggregations, star schemas, measure patterns, Tabular Editor scripting, field parameters). • Governance & documentation: Drove data governance with KPI glossaries, lineage documentation (Confluence-ready), and metadata-driven standards to keep definitions consistent across teams. • Quality engineering: Implemented automated data quality checks (uniqueness, referential integrity, staleness, cross-table reconciliation) with actionable alerting (e.g., Slack) and clear remediation workflows. • CI/CD & environment strategy: Established DEV/TEST/PROD separation and introduced Git-based versioning and deployment practices for Fabric/Power BI artifacts to reduce risk and improve release reliability. • Security & access design: Delivered pragmatic RLS/OLS approaches and identity patterns (service principals/fixed identity) to enable secure self-service analytics at scale. • Stakeholder collaboration: Partnered closely with analysts, engineers, and leaders to translate ambiguous questions into clear metrics, data contracts, and decision-ready dashboards.
Developed a highly utilized customer 360 tool combining MicroStrategy Dossier and Power BI dashboard. Consolidated client interactions, consulting engagements, support tickets, and education services data. Enhanced customer relationship management and identified areas for improvement.
As a project manager, I led successful projects migrating MicroStrategy platform from on-premise to the cloud. I planned and defined project scope, assembled cross-functional teams, and managed vendor relationships. I oversaw critical activities around the cloud platform set up. Effective communication and rigorous testing ensured reliable functionality and performance. My technical expertise and strong project management skills delivered successful migrations to cloud-based BI platforms.
