About

Software engineer with 15+ years of experience. I take on big projects and see them through, from design to rollout. At Kittl I built the subscription and payments platform, then the AI generation platform. I work closely with product, design, and other engineering teams. Main tools: TypeScript, Node.js, PostgreSQL, Python, Stripe, and AWS.

Work Experience

2024 - Present

Senior Software Engineer

Engineer on the monetization team, then the AI Product team. Technologies: TypeScript, Node.js, PostgreSQL, Prisma, Stripe, Redis, and AWS.
  • Built a dynamic pricing system, so prices can be set per country without code changes.
  • Expanded the payment system to support multiple Stripe accounts across regions.
  • Moved subscriptions from user level to workspace level, so one owner can pay for many workspaces and seats.
  • Made payment flows safe against race conditions and duplicate charges using locking and idempotent requests.
  • Built a CMS-driven AI model system, so new image and video models can be added through config instead of code changes, and non-engineers can ship them without us.
  • Added multi-provider AI generation with automatic fallback and traffic splitting between providers.
  • Added video generation, image editing tasks like inpainting and outpainting, and token pricing based on input options and subscription plan.
