Profile: https://flows.cv/sleyter

Software engineer with 5+ years building high-performance, data-intensive applications for fintech, gaming, and investment platforms in New York City.

I specialize in real-time UI systems, complex data interfaces, and API-driven architectures. My core stack is React, TypeScript, WebSocket, and GraphQL, with full stack experience across Node.js, Django, PostgreSQL, and AWS. I am comfortable owning features end to end, from architecture decisions through to deployment.
My background spans prime brokerage fintech, retail sportsbook platforms, real estate investment tools, and high-traffic auction marketplaces. Across all of it I have built interfaces that handle high-frequency data updates, real-time state synchronization, and complex hierarchical data relationships at production scale. I have owned features end to end, led code reviews, built and maintained internal component libraries, and contributed to full platform migrations from legacy architectures to modern stacks.

What ties all of my work together is a consistent pattern: taking complex, ambiguous requirements and translating them into interfaces that feel simple and fast to use. That requires holding both the technical architecture and the user experience in mind simultaneously, and I have done that across regulated fintech, high-traffic consumer platforms, and data-heavy investment tools.

Right now I am focused on the intersection of frontend engineering and AI. I want to build the interfaces that make AI agents and LLM-powered products actually usable at a high level. Most AI products today are chat boxes. The next generation of AI interfaces is a fundamentally harder and more interesting problem, and that is where I want to be.

Open to frontend, full stack, and AI product engineer roles at AI-native companies and high-growth startups. Also available for contract and freelance engagements.
