About
I build systems that scale. Currently SDE3 at Walmart Global Tech designing payroll infrastructure for millions of employees. Previously founded a music-discovery startup and scaled a social platform to 650k+ users. I love hard engineering problems at the intersection of distributed systems and product.

Walmart Global Tech
Software Engineer III
2024 – Present
Seattle, WA
- Orchestrated a high-scale payroll computation engine using Spring Boot and Apache Spark on GCP Dataproc, automating end-to-end processing for 2M+ employee records with 100% audit compliance.
- Engineered a real-time benefits eligibility pipeline via Cosmos DB Change Data Capture and Kafka with consumer groups and dead-letter queues, reducing system latency by 24% and false-positive alerts by 45%.
- Designed and implemented the Transaction Stack pipeline — an automated error-remediation system that replays associate payroll data from a validated Checkpoint state, eliminating manual cross-team escalations.
- Standardized RESTful service contracts via OpenAPI specifications across the Payroll Integration Engine, Watchtower, and Checkpoint Service, reducing cross-team integration cycles from weeks to days.
- Authored the design for Engram, an AI-driven payroll reconciliation system that detects anomalies in historical payroll data via outlier analysis on Walmart's internal AI agent platform.

Audion Technologies
Founder & CEO
2021 – 2022
Atlanta, GA
- Founded Glimpz and led full-stack development on a unified Ionic React and AWS Amplify codebase delivering a consistent music discovery experience across mobile and web.
- Built a personalized recommendation engine using Spotify's audio feature vectors and genre/artist metadata — scoring track affinity against user listening history while computing user-to-user similarity.
- Architected a fault-tolerant AWS Batch crawling pipeline to ingest and deduplicate a 20M+ song catalog, implementing rate-limit-aware scheduling and idempotent checkpointing.
- Integrated Spotify Web API and Apple MusicKit JS to enable one-tap track saving, handling OAuth token refresh and cross-platform rate limits.
Projects
RDVous
Private iOS Couples App
A full-stack private iOS app for couples featuring shared postcards, boards, voice whispers, and a paired calendar — built on SwiftUI/Combine with a TypeScript Firebase backend.
- Engineered a two-phase postcard image upload pipeline that acquires a stable Firestore document ID, uploads pair-scoped full/thumbnail images, and rolls back on failure to prevent orphaned records.
- Built a hybrid real-time/paginated feed using a live Firestore snapshot listener for instant delivery and cursor-based pagination for history, with pair-scoped access control via security rules.
GoalGroup
Collaborative iOS Goal-Tracking
A collaborative iOS goal-tracking app used by a real weekly accountability group, supporting short/medium/long-term goals, shared habit tracking, todos, and group management.
- Implemented a fully configurable iOS Home Screen widget via WidgetKit's AppIntentConfiguration (custom filters, fonts, colors), syncing goal state from Firestore through a shared App Group UserDefaults bridge.
- Built deep-link group joining and a repository-pattern Firestore layer cleanly separating data access for goals, habits, todos, groups, and users.
