  • Supported vendor selection, route/cost decisions, and high-volume tour processing at approximately 3,000-4,000 tours/day across daytime and evening workflows (internal estimate).
  • Resolved cross-service bugs, API integrations, SQL migrations, and data-flow issues; improved performance by narrowing database queries to required data only.
  • Built and maintained 200+ Grafana dashboards and alerts for multiple teams using Prometheus and Splunk, with Opsgenie notifications.
  • Supported Jenkins pipelines for dev / int / prod and AWS configuration tasks (including JSON outputs stored in S3), with regular collaboration across PO / PM / BA.

Full Stack Developer

Colengo by Tek Def Co., Ltd.
05.2022 - 09.2024
  • Built and maintained the full-stack oneCORE platform for admin operations (products, users, shipping, payments, site management) across 10+ companies / multiple storefronts.
  • Designed and implemented configurable-product behavior in the admin system, including multi-step product structures, dynamic controls, selection constraints, and cross-step dependency rules (show/hide/disable).
  • Worked deeply across the stack in a 2-developer team: Angular admin UI, .NET Core APIs, SQL Server data modeling, CQRS foundation work, and API optimization.
  • Developed customer-facing storefronts with ASP.NET Razor Pages (SSR) + TypeScript and delivered reusable SEO/performance improvements (semantic markup, indexing, page speed, structured content) across shops.
  • Built campaign features and contributed to SEO/storefront performance improvements for client storefronts; one storefront recorded approximately ~USD 200,000 in first-week sales after deployment, and I supported 8+ storefronts (including Tabledusud, Livecard.net, and AmsterdamNightLife) in the oneCORE ecosystem (internal observation).
  • OneCORE e-commerce admin platform + multi-shop storefronts
  • Tech: C#, .NET Core, ASP.NET Core, ASP.NET Razor Pages, Angular, SQL Server, TypeScript, CQRS, SEO

  • Contributed full-stack to Anyday (Denmark-based payment-splitting fintech) admin tooling for installment-payment operations, including schema changes, APIs, batch jobs, and Angular UI for webshop user management and credit-limit evaluation.
  • Worked within a CQRS-style, log-driven data flow (state rebuilt from logs/read models), and automated monthly credit-limit jobs to reduce manual admin work; batch execution completed all users in approximately 1.5 hours with no job failures during runs.
  • Internal staffing app + client-facing fintech admin tooling (Anyday, Denmark-based payment-splitting fintech)
  • Tech: Angular, TypeScript, .NET Core, Node.js, SQL Server, Firebase, CQRS
