Intuit

Senior Backend Engineer, QuickBooks Bill Pay / B2B Payments

Java-based B2B payments service on Intuit's QuickBooks Bill Pay team, following an internal transfer from Data Exchange Platform: hardening payment validation and correctness, and automating stale Payment Instruction lifecycle cleanup.

• Hardened batch-level payment validation and abort handling in the B2B payments service: blocked unsupported Credit Card + Real-Time Payments (RTP) batch combinations before persistence or downstream processing, and corrected abort handling for pending-approval credit-card Payment Instructions — preserving existing validation precedence and payment-state behavior.
• Implemented runtime-refreshable configuration for Payment Instruction auto-abort expiration (TTL).
• Designed and built a ShedLock-coordinated scheduled job — a single runner per sweep — that discovers and safely aborts stale in-flight Payment Instructions, replacing full-table scans with a self-owned, end-to-end-provisioned sparse, sharded DynamoDB GSI for age-ordered discovery, revalidating authoritative state before every abort as a distributed-correctness guard, and adding a global kill switch, company-level feature-flag gating, and per-candidate failure isolation.
• Implemented read-path filtering that excludes failed credit-card Payment Instructions from Payments UI/API results, preserving existing behavior for ACH and legacy payment methods.

Intuit

Senior Backend Engineer, Data Exchange Platform / IDX

Core contributor on a centralized distributed execution engine that processes millions of executions per minute across tens of thousands of API and scraping-based data providers, deployed on AWS and Kubernetes.

• Extended and maintained a decision-routing execution engine that reads a per-provider configuration and dispatches work across REST, XML/SOAP, and DOM-based scraping execution paths.
• Drove the migration of a 15-year-old legacy scripting pipeline onto a modern internal execution engine, with zero customer-facing disruption.
• Built engine extensions for document (PDF) data extraction and for publishing results to internal event streams mid-execution, decoupling downstream consumers from full script completion.
• Owned retry and failure-handling logic across a hybrid Kafka/Pulsar event-driven architecture, guaranteeing at-least-once processing for high-volume financial data flows.
• Extended and stabilized an internal Model Context Protocol (MCP) integration that lets Claude and other AI agents submit AI-generated code changes into an internal review pipeline. Owned the agent-upload flow and the automated test-migration tooling around it.

UMTB Bank

Senior Backend & Platform Engineer

Platform and developer-experience lead on a greenfield banking platform. Owned the Kafka routing layer end-to-end and took majority ownership of the BFF infrastructure that generates and runs the bank's backend-for-frontend services.

• Designed and owned a centralized Kafka router, independently and through self-directed research, later validated with the principal architect, handling millions of monthly events with automated error-based routing and dead-letter-queue management.
• Built a BFF-as-a-Service platform that generates NestJS services from Swagger specs, cutting new-service creation time from days to hours, and took ownership of roughly 70% of that infrastructure layer's codebase.
• Built a regenerate.keep preservation policy that let developers run the standard regeneration flow against a newer Swagger version while carrying their own files forward untouched.
• Developed and maintained core Node.js SDKs (HTTP, Kafka, Redis) used across 50+ microservices to enforce architectural consistency.
• Maintained 82%+ automated test coverage using Testcontainers for realistic integration testing in a regulated banking environment.
• Acted as the team's onboarding focal point. Built the technical onboarding roadmap and was the go-to engineer for platform and production questions.

Momentum

Full-Stack Engineer, Fintech

Full-stack engineer on a fintech product, re-architecting analytics pipelines and owning payment integration correctness.

• Re-architected real-time analytics pipelines (NestJS + React), driving a measurable increase in sales conversions.
• Tuned PostgreSQL queries, indexing, and joins to deliver sub-second latency on million-row datasets.
• Owned end-to-end integration of payment providers, ensuring reconciliation accuracy and financial correctness.

2021 – 2023

Harel Insurance

Full-Stack Engineer

Full-stack engineer on insurance processing systems: asynchronous messaging, internal tooling, and data migration.

• Designed and owned asynchronous inter-service workflows using RabbitMQ, guaranteeing reliable message delivery across insurance processing pipelines.
• Built a React + Node.js configuration dashboard backed by HashiCorp Vault, enabling secure live updates of application settings on Kubernetes without a deploy: the UI loads a secret from Vault, an AWS Lambda applies it to the target Kubernetes ConfigMap, and the affected pipeline reruns with the new configuration.
• Used MongoDB to manage service configuration as data, letting product managers update settings directly without developer involvement.
• Engineered a Java-based ETL pipeline to migrate data from an on-premise relational database to MongoDB, handling transformation, sanitization, and secure transfer.
• Delivered GDPR-compliant workflows with encryption at rest and secure PII handling.
• Architected multi-layered caching (Redis + in-pod) to improve stability and response times for high-traffic customer portals.

2018 – 2021

Israel Air Force

Full-Stack Engineer

Full-stack engineer building secure command-and-control and network-monitoring systems in a mission-critical defense environment.

• Designed and delivered secure command-and-control platforms managing communications across multiple sites.
• Built a real-time event-ingestion pipeline processing live SNMP traps from network units, routing alerts immediately to sustain 99.9% uptime for mission-critical systems.
• Implemented SNMP-based network management for programmatic configuration and control of network units.
• Delivered secure-by-design systems with encryption protocols validated through penetration testing.
