I’m a software engineer with about 5 years of experience building fast, clean, and maintainable systems that help users solve real problems. I enjoy owning work end-to-end—from clarifying ambiguous product goals to shipping scalable features—across web, mobile, and backend, especially in complex domains like in-app trading, crypto payment flows, and KYC compliance. Recently, I’ve helped turn vague ideas into production-ready capabilities, including real-time, LLM-driven “agentic” features, while also strengthening reliability through refactoring, testing, and CI/CD improvements. I’m comfortable spanning Flutter, TypeScript/React/Next.js, and Node.js, and I like building integrations that are secure, measurable, and easy for teams to maintain.…I’m a software engineer with about 5 years of experience building fast, clean, and maintainable systems that help users solve real problems.
