About

Professional summary

I am a full-stack software engineer specializing in backend architecture and third-party API integrations, with hands-on experience building and hardening production systems.

I have worked across fintech, backend engineering, and mobile development, with a strong focus on reliable, secure, and scalable products.

As Co-founder and CTO at Wrap Investing, I led end-to-end product development, including the Go backend, cross-platform mobile app, and non-custodial wallet layer.

My work has included brokerage integrations, KYC/AML onboarding, JWT authentication, idempotent financial transactions, TLS hardening, rate limiting, and secure deployment practices.

I also have experience with Flutter, React, Next.js, PostgreSQL, Docker, AWS, Solidity, and account abstraction concepts such as ERC-4337.

In parallel, I have taught data engineering and programming, and I enjoy applying analytical thinking from poker and chess to software design and problem solving.

I am currently seeking remote backend or full-stack roles where I can contribute to technically challenging products and continue growing in secure, product-focused engineering.
