Overview
End-to-end cloud data platform for a fast-growing neobank, with core event tables ingesting large volumes of data daily and hundreds of terabytes of cumulative data. The platform underpins reconciliation, partner integrations, and financial reporting – operating on a cloud-managed infrastructure where both reliability and regulatory compliance are non-negotiable. Given the nature of the business, any pipeline failure or data discrepancy carries direct financial and audit consequences.
Achievements
Automated reconciliation pipelines for primary payment gateways, eliminating the vast majority of manual effort and materially strengthening audit readiness. Built internal tooling for workflow generation that became a team-wide standard, significantly compressing the time from requirement to deployed pipeline. Improved execution times on core legacy workflows through architectural refactoring. Designed a data compaction system for cold storage that reduced both read latency and long-term maintenance costs. Identified and resolved a query efficiency issue that measurably reduced cloud compute consumption at the organizational account level — one of the more impactful cost engineering wins on the platform.
Responsibilities
- Migrated reconciliation and partner-integration pipelines from self-hosted to cloud-managed orchestration, eliminating a category of infrastructure failure and freeing the team from operational toil.
- Designed automated reconciliation pipelines for primary payment gateways, replacing error-prone manual processes with auditable, testable data flows.
- Built internal tooling for DAG generation and operational workflows, establishing consistent patterns that reduced both development time and onboarding friction across the team.
- Refactored legacy workflows using modular DAG patterns and dynamic task mapping, achieving substantial gains in average execution time.
- Worked closely with finance and compliance teams to ensure data automation aligned with regulatory requirements.

Multi-Asset Market Data Platform
Senior Data Engineer
Mission-critical market data platform covering equities across dozens of global exchanges, FX, and fixed income, serving both internal quantitative trading desks. At this scale and in this context, reliability is not a quality attribute – it is the product. The system had to sustain consistent ingestion and low-latency access during peak trading hours across multiple time zones, with no tolerance for data gaps or processing delays that could affect trading decisions.
Enterprise Data Warehouse Migration & Recommendation Systems
Senior Data Engineer
Data platform modernization for one of the largest US retail chains, spanning over a thousand physical stores and a major e-commerce operation. The scope covered legacy warehouse migration, recommendation pipeline rebuilding, and data governance implementation – all across a petabyte-scale environment without disrupting ongoing retail analytics.
