Work Experience

• Senior Back-End Software Developer, Roofr

  Apr, 2023 - Present

  Senior backend engineer contributing to core domain services (payments, invoicing, proposals), with an emphasis on DDD-style architecture, reliability, and raising engineering standards across production systems.

  • Introduced Value Objects as a mechanism for encoding business rules at the domain boundary; the pattern was adopted across three other teams, shifting how the org approached domain integrity and invariant enforcement.

  • Advocated for clear domain boundaries across services — reducing cross-team coupling, enabling teams to build deeper expertise within their domain, and increasing autonomous delivery.

  • Led architectural transition from ORM-coupled models (CycleORM) toward repository-based domain boundaries, improving decoupling, testability, and long-term system flexibility.

  • Drove cross-team alignment on authorization patterns through reusable policies and typed DTOs, clarifying access boundaries and reducing duplication.

  • Introduced stricter pre-merge validation gates (static analysis, enforced test suites, custom PhPStan rules), reducing regression risk and increasing engineering accountability across services.

  • Standardized local development workflows to reduce environment drift and improve confidence in pre-merge validation and onboarding.

  • Led post-incident analyses for production issues, identifying root causes and driving preventative changes to reduce recurrence.

  • Authored and supported RFCs to improve engineering standards, development workflows, and architectural consistency across teams.

  • Tech: PHP 8, Laravel, PostgreSQL, Redis, Docker, GitHub Actions, PHPStan, Sentry, MetaBase

• Senior Full-stack Software Developer / Tech Lead (Pricing Domain), SSENSE

  Nov, 2017 - Jan, 20235 years 2 months

  Led the Pricing domain to improve correctness, performance, and availability of global price calculation and related services.

  • Led the Pricing domain team, guiding feature exploration, technical design, and delivery with a focus on scalability and operational safety.

  • Modernized parts of a legacy monolith by extracting capabilities into cloud-native services.

  • Built an eventually-consistent framework for near real-time per-product aggregates from multiple data sources, minimizing incremental effort for new aggregate types.

  • Designed and deployed a Slack integration to query real-time product information (price, stock, description, discounts) from internal systems.

  • Owned incident response and post-incident reporting for production services, defining mitigation strategies and preventative actions.

  • Contributed to engineering standards through code reviews, coaching, and participation in hiring (interviews + debriefs).

  • Tech: PHP, Python 3, Lambda, DynamoDB, SQS, S3, SNS

• Lead Code Auditor (Internal Product Security Team), MindGeek

  Feb, 2017 - Nov, 20179 months

  Tech lead for internal product security reviews and security engineering guidance across teams.

  • Reviewed internal applications to identify security weaknesses, bugs, exploit paths, and violations of secure coding standards.

  • Provided technical guidance to security analysts and engineering teams; contributed to security awareness trainings for new hires.

  • Triaged bug-bounty submissions, assessed impact, and coordinated follow-ups with engineering and infrastructure stakeholders.

• Tech Lead / Senior Software Developer, MindGeek

  Oct, 2010 - Feb, 20176 years 4 months

  Led teams and services across multiple products; later worked on a high-traffic advertising platform improving CMS and analytics capabilities.

  • Led a team of ~7 developers across multiple projects; served as the interface between frontend, backend, and product stakeholders.

  • Redesigned and consolidated inherited codebases to reduce duplication and improve maintainability across multiple services.

  • Designed a framework to unify multiple domains into a single backend codebase, reducing development and maintenance overhead.

  • Improved performance and reliability by identifying bottlenecks, tuning systems, and supporting production operations.

  • Participated in hiring by running technical interviews and contributing to debrief sessions.

Projects Experience

• Serverless-offline-lambda-docker

  - Present

  Serverless plugin enabling local development with Serverless Offline while deploying AWS Lambda as Docker images via CloudFormation, to keep local/dev/prod behavior closer and reduce friction.

  • Improved local development ergonomics for teams using Lambda container images.

  • Focused on transparent developer experience: same workflow locally and in AWS.

• Cachier (bug fix contribution)

  - Present

  Contributed a backwards-compatible fix for a bug that could lead to deadlocks under certain conditions, implemented as an opt-in behavior for users.

  • Bug fix with careful backwards-compatibility considerations.

• S3rver (bug fix contribution)

  - Present

  Fixed an issue with improper handling of HTTP Range requests, which caused downstream failures for clients relying on correct partial-content behavior.

  • Improved protocol correctness for local S3-compatible development tooling.

• Serverless-step-functions-local-docker

  - Present

  Fixed configuration behavior so the stage is resolved from provider configuration and falls back to legacy values when required.

  • More robust configuration resolution while preserving legacy compatibility.
