# Nicholas Young

> Senior Software Engineer | AI System | C#, React, Angular | Fintech, Healthcare, SaaS & Startups

Location: North Tonawanda, New York, United States
Profile: https://flows.cv/nicholasyoung

I’m a senior full‑stack engineer with 10+ years of building production systems across fintech, healthcare, and SaaS. Translation: I’ve spent a decade making sure apps don’t crash when thousands of people hit “refresh” at the same time.

• Backend wizardry: C#/.NET, Python, microservices — basically the plumbing that keeps everything flowing.
• Frontend fun: React, Angular, Next.js — turning complex workflows into clean, modern interfaces that don’t make users cry.
• Performance tuning: I enjoy refactoring legacy code the way some people enjoy Sudoku — oddly satisfying.
• Team stuff: I mentor engineers, lead reviews, and try to keep meetings shorter than a Netflix episode.
• AI integration: I’ve been sneaking ML services, embeddings, and LLM features into products like secret ingredients — enhancing workflows without breaking the recipe.

At the end of the day, I’m about shipping dependable systems, helping teams grow, and finding clever ways to bring new tech into the mix. If you’re building something ambitious and want it to scale without drama, I’m your guy. Bonus: I promise not to name variables after Game of Thrones characters… anymore.
