Data Engineer II
Over the past several years at Amazon, I have worked at the intersection of data engineering, finance technology, and large-scale analytics—designing, developing, and scaling critical data pipelines and platforms that directly influence multi-billion-dollar decision-making. My role centers around enabling the WW Stores FinTech and Global Finance teams with reliable, secure, and timely data that leadership depends on for operational visibility, compliance, and strategic planning.
I specialize in architecting cloud-native pipelines on AWS, optimizing Redshift workloads, building BI reporting solutions, and implementing governance standards across global datasets. In doing so, I have delivered innovations in real-time revenue insights, platform scalability, compliance readiness, and operational reliability. Beyond technical execution, I lead engineering initiatives, mentor Data and BI Engineers, and partner with leadership to align long-term strategy with Amazon’s business objectives.
Below is a detailed account of the scope and impact of my work at Amazon:
Real-Time Insights | Insist on the Highest Standards + Data Modeling
One of my most impactful contributions was the design and deployment of a layered hourly dataset for intra-day ASIN-level revenue insights. Previously, financial reporting relied heavily on daily aggregates, limiting leadership’s ability to respond to fast-moving market and operational shifts.
I built a multi-layered data pipeline with raw, staging, and denormalized layers that systematically transformed order and item activity into a robust hourly dataset. To ensure accuracy and alignment with daily customer order item (DUCOI) metrics, I implemented:
• MD5 hash change detection for efficient deduplication and change tracking.
• Record versioning to maintain historical integrity and allow point-in-time analysis.
• Business rule transformations to handle revenue allocation, cancellations, and late-arriving data.
• Time zone normalization for global financial reconciliation.
The result was a high-fidelity, intra-day reporting dataset that empowers the Amazon Stores Finance Team to conduct near real-time financial analysis. This solution now supports decision-making across leadership levels, enabling faster insights into ASIN-level performance, demand spikes, and regional sales patterns. It has directly influenced how the finance organization evaluates performance in fast-moving business contexts such as promotions, product launches, and holiday events.
ETL Automation & Reliability | Customer Obsession + SLA Governance
Reliability is the cornerstone of financial data reporting. In 2024, I led a pipeline reliability program for the Daily Sales Flash (DSF)—a flagship dataset used by S-Team (including the CEO and VPs) to track sales.
Key initiatives included:
• Pipeline failure reduction: Identified and eliminated systemic failure points by refactoring scripts and improving orchestration logic.
• Proactive alerting: Integrated Klaxon alarms across all DSF profiles to provide real-time monitoring and automated escalation.
• SLA governance: Designed automated SLA adherence checks and validation layers that alert engineers and stakeholders of potential breaches.
These improvements increased pipeline SLA adherence to 99.7% in 2024, ensuring that leadership always has access to accurate, timely DSF metrics. This program directly reinforced the WW Stores FinTech team’s mission of delivering trustworthy financial data to inform strategy, investor relations, and quarterly financial reporting.
Scalable Data Platforms | Think Big + Data Architecture
Amazon’s platform scalability demands constant reinvention. I took ownership of the Andes 3.0 migration, one of the largest data infrastructure modernization efforts, spanning nearly 7000 tasks across multiple organizations.
My contributions included:
• Designing scalable orchestration workflows to migrate pipelines with zero downtime.
• Refactoring data tasks into modular, reusable components, reducing maintenance overhead.
• Establishing documentation best practices to onboard new engineers and accelerate adoption.
• Partnering with cross-org stakeholders to align migration milestones with VP-level goals.
The Andes 3.0 migration not only modernized infrastructure but also improved cost efficiency, reliability, and scalability of financial data pipelines. The success of this initiative has become a reference point for future migrations, demonstrating how large-scale platform shifts can be executed with minimal business disruption.
Performance Optimization | Dive Deep + Redshift WLM Tuning
Redshift sits at the heart of Amazon’s finance reporting ecosystem. Performance bottlenecks in clusters were impacting SLA compliance and delaying leadership dashboards.
To address this, I:
• Tuned Workload Management (WLM): Segmented queries into prioritized queues based on business criticality.
• Optimized ETL pipelines: Re-engineered query logic, restructured tables with appropriate sort/dist keys, and applied compression.
• Implemented monitoring dashboards: Built near real-time performance metrics dashboards to track cluster utilization.
These improvements reduced query times, eliminated SLA breaches, and ensured leadership reports—including S-Team sales trackers—were delivered on time. The initiative exemplified operational excellence by balancing performance with cost efficiency.
BI Reporting & Leadership Insights | Deliver Results + Business Intelligence
Recognizing the need for accessible financial insights, I developed BI dashboards and reports consumed directly by Amazon’s highest levels of leadership.
Highlights include:
• IN FP&A Daily Sales Flash Metrics: A critical dataset that integrates into finance workflows across multiple marketplaces.
• QuickSight dashboards: Built executive-facing dashboards enabling S-Team leaders to track near real-time sales trends.
• Self-service tooling: Designed dashboards with drill-down capabilities, empowering finance analysts to explore data without engineering dependency.
These solutions have been instrumental in leadership decision-making, offering visibility into financial performance across countries, marketplaces, and product categories.
Data Ingestion & Accuracy | Frugality + ETL Automation
Data ingestion for external and cross-team datasets is often prone to manual errors. I automated ingestion for critical datasets, including:
• Foreign Exchange (FX) Rates
• Marketplace Finance (MP Finance)
• Curves Upload for forecasting models
By implementing validation layers, deduplication checks, and schema-driven ingestion workflows, I reduced manual errors by 80%, significantly improving the accuracy and reliability of downstream financial models and reports.
Compliance & Governance | Earn Trust + Data Governance
Compliance is non-negotiable in global finance. I spearheaded several governance initiatives to align with regulatory and internal audit standards:
• DMA and GDPR readiness: Ensured data pipelines adhered to European data privacy and portability requirements.
• Kale Attestation & EU Seller Tagging: Standardized tagging and attestation across 20+ datasets for legal compliance.
• Credential management: Migrated legacy Chime webhook and EC2 script credentials into AWS Secrets Manager, enhancing security posture and reducing operational risk.
These initiatives not only ensured compliance but also improved stakeholder confidence in Amazon’s ability to handle sensitive financial data securely and transparently.
QuickSight Dashboarding & Operational Excellence | Think Big + BI Tooling
Beyond leadership reporting, I developed operational dashboards to drive accountability and governance across teams:
• Permission Audit Dashboard: Gave leaders visibility into dataset access, reinforcing least-privilege principles.
• SLA Tracker Dashboard: Provided real-time adherence tracking, enabling proactive resolution of potential misses.
• Category Details Dashboard: Delivered category-level financial insights to support pricing and product strategy.
By standardizing reporting and reducing manual tracking, these dashboards improved transparency, governance, and leadership decision velocity.
Leadership & Mentorship | Learn and Be Curious + Enablement
Technical impact is amplified through people. I have consistently invested in mentoring and enablement:
• Mentored new Data Engineers and BI Engineers, accelerating their onboarding and career development.
• Conducted SQL workshops to upskill engineers and analysts across teams.
• Actively participated in Amazon hiring panels, ensuring high standards in recruiting top talent.
These contributions fostered a culture of technical excellence, curiosity, and continuous learning.
