I'm a product-focused frontend / full-stack engineer with 10+ years of experience building and shipping user-facing applications. I work close to the product, own problems end-to-end, and enjoy turning complex systems into clear, intuitive, high-leverage experiences.

I care deeply about UX, system clarity, and reducing friction—between frontend ↔ backend, product ↔ engineering, and users ↔ complex technology. While frontend is my core strength, I regularly step outside strict role boundaries when it helps the team move faster or build better abstractions.

• Building a B2B SaaS ticketing platform (validating product-market fit)
• Experimenting with AI-assisted development workflows (Claude Code, Cursor, MCP protocols, CodeRabbit)
• Open to full-stack or frontend engineering roles (remote/hybrid)

Frontend & Product: Building user-facing applications with focus on UX, clarity, and accessibility
Full-stack Integration: Complex systems spanning frontend ↔ backend ↔ Web3/blockchain

I helped take the product from idea to mainnet, scaling to: 2M+ users, $7M TVL, $55M+ trading volume.

I initially led frontend and product initiatives, then stepped deeper into the backend when gaps appeared. To unblock progress, I ramped up on Rust and Go, identified avoidable system complexity, and helped remove a CosmWasm proxy layer that was increasing coupling and slowing development.

Impact:

• Clearer system boundaries
• Lower maintenance overhead
• Faster iteration
• Better cross-team collaboration and onboarding for new hires

Below you'll find pinned repositories showcasing different aspects of my work—from production applications to experimental tools. Each has detailed READMEs explaining the problem, approach, and tech stack.

I contribute to open source when it helps solve real production problems—whether that's debugging tricky issues, improving documentation, or collaborating with maintainers.

• Product first — user needs, clarity, and reliability come before abstractions
• Ownership — comfortable being accountable for the final user-facing result
• Collaboration — close work with design, backend, and stakeholders
• Adaptability — learn new tools quickly when the problem requires it
• Pragmatism — simple solutions beat clever ones

I enjoy working on early-stage products, improving onboarding flows, and helping teams move faster with less friction. I'm especially drawn to roles where engineering, product, and real users intersect.

Beyond product work, I love exploring new technologies, whether it's building mining rigs, tinkering with hardware setups, or experimenting with new frameworks and tools. Staying hands-on with tech keeps me curious and constantly learning.

I'm currently open to full-stack or frontend engineering roles (remote or open to relocate).
