I build scalable financial and data systems that operate in real-world, high-volume environments.
 
I’m a Software Engineer with 8+ years of experience across startups, global tech companies, and AI-focused organizations. My work focuses on financial infrastructure, distributed systems, and AI-powered applications, designing systems that handle complex workflows, high-throughput transactions, and production-scale data.
 
At Overflow App Inc., I design and scale backend systems for a nonprofit financial platform processing over $1B annually across ~1,000 organizations, supporting both traditional payments and non-cash assets like stock, cryptocurrency, and donor-advised funds . My work includes building payment infrastructure (Apple Pay, Google Pay, Tap-to-Give), distributed data pipelines processing millions of records, and AI systems such as natural language → database query pipelines with secure multi-tenant data controls.
 
Previously, at Amazon, I contributed to backend systems powering global hiring infrastructure supporting ~1.5M workers, building scalable services and event-driven pipelines across regions. I also worked with Scale AI, where I evaluated and improved LLM-generated code systems for real-world engineering use cases.
 
Beyond my core work, I’m actively building AI-native systems, including an AI-first ERP and developer tools exploring how AI can function as a core system layer, not just an add-on. My focus is simple: build systems that scale, handle real-world complexity, and apply AI where it actually works in production.

Beyond engineering, I’m driven by curiosity, exploring the intersection of AI and cloud systems, and occasionally diving into astronomy and the broader questions around complex systems and the universe.
