Matt McFarlane
Senior Software Engineer
Summary
I'm a senior software engineer at FanDuel, where I've spent almost 4 years working in the Core Marketing Platforms vertical, progressing from Junior to Senior in under 3 years. Day to day I own a portfolio of 10 services handling up to 50k RPS, lead system design, mentor engineers towards senior, and work closely with stakeholders and product. I also have an engineering background (BEng in Aircraft Engineering and an MSc with Distinction in Mechanical Engineering) which shapes how I approach technical problems.
Experience
Senior Software Engineer
Mar 2025 — PresentFanDuel · Full-time · Remote
- Senior engineer within the Core Marketing Platforms vertical, owning a portfolio of 10 services handling up to 50,000 requests per second.
- SME for the domain: leading system design, defining technical direction, and managing architectural trade-offs across the team of 10.
- Own end-to-end delivery of engineering initiatives, from requirements and design through to production, including risk identification and mitigation.
- Lead technical integration with third-party providers, owning the design, stakeholder alignment, and delivery across teams.
- Work closely with stakeholders and product across vertical and cross-functional teams to shape and prioritise engineering work.
- Responsible for platform reliability and scalability across a distributed Java microservice architecture on AWS, using Kafka, Flink, and event-driven patterns.
- Set technical standards within the team, guide architectural decisions, and support good engineering practices.
- Mentor junior and mid-level engineers through 1:1s, code reviews, and pairing, with a focus on helping them progress towards senior.
- On-call for the Core Marketing Platforms domain, owning incident response and resolution.

Notable Work
Internal Polling Framework Library
FanDuelDesigned, built, and maintains an internal Java library adopted across multiple engineering teams.
- Provides a configurable, task-based execution framework backed by RDS task queues — services store tasks, the library polls and handles execution.
- Exposes configuration for orphan task detection, orphan polling intervals, and continuous heartbeating for long-running tasks.
- Built for high resilience in multi-pod environments, handling concurrent execution safely across horizontally scaled services.
- Reduces boilerplate across teams and gives them a consistent, well-tested pattern for async task processing.
Service Standards & Maturity Framework
FanDuelDeveloped vertical-wide standards and tooling to raise and maintain the quality of services going to production.
- Created a service requirements checklist for new services entering production, covering observability, monitoring, documentation, performance, and security.
- Developed a service maturity matrix letting teams grade their services across key dimensions, with defined tiers (Basic, Standard, Optimised, Innovative) and clear guidance at each level.
- Gives teams a structured way to identify weak spots and prioritise engineering investment rather than letting standards drift.
- Rolled out across all teams in the vertical, working directly with staff engineers to get buy-in and make sure it fit how each team actually works.
Streaming Platform Adoption & Migration
FanDuelFirst team to onboard to a new internal data streaming platform, establishing the patterns and tooling used by subsequent teams.
- Led the migration of use cases from a legacy service to the new streaming platform, designing reusable transformations and golden path patterns to accelerate adoption across teams.
- Built shared libraries enabling other teams to connect to the platform quickly, reducing onboarding friction and ensuring consistency across integrations.
- Onboarded and guided a contracting team brought in to assist with migrations — providing technical direction, conducting code reviews, and maintaining quality standards throughout.
- Acted as the internal SME for the streaming platform within the vertical, sitting between the platform team and consuming teams.
Third-Party Vendor Assessment
FanDuelLed technical due diligence and POC integration work to assess the suitability of third-party vendors.
- Designed and built POC systems to evaluate vendor integrations, assessing technical fit against FanDuel's architecture and requirements.
- Conducted performance testing using Locust to validate vendor capacity against required RPS thresholds.
- Documented findings and presented evidence-based recommendations to stakeholders on vendor suitability, covering performance, reliability, and integration risk.
Legacy Service Migration & Decomposition
FanDuelLed the full rewrite and decomposition of a legacy EC2-hosted service into two modern microservices.
- Migrated a core service from legacy EC2 infrastructure — built on Google Guice and poorly-understood internal frameworks — to two well-defined Spring Boot microservices deployed via Helm to EKS.
- Decomposed the service deliberately: extracting a reusable piece of functionality into a shared microservice consumed by multiple teams, and isolating the core domain logic into a separate service with clear ownership.
- Designed and executed full RDS schema migrations and data replication strategies, with no data loss or duplication during cutover.
- Improved maintainability, observability, and deployment consistency by removing legacy dependencies and bringing the services in line with the team's current platform standards.
