Profile Description

Hi! I’m Nathaniel — a Senior Full-Stack Engineer, UI/UX-focused builder, and creative technologist with experience shipping production-grade products across frontend, backend, infrastructure, blockchain systems, and design.

Over the past year, I rapidly grew from Junior to Senior Full-Stack Engineer at a UK/Singapore-based blockchain company by leading high-impact product work, performance optimization, and cross-stack system improvements across multiple live platforms.

My work focuses on building fast, reliable, and scalable systems while keeping UX clean, intuitive, and maintainable.

I’ve worked on:
• Full-stack web apps using React, Next.js, TypeScript, Node.js, PostgreSQL, Firebase, ----------
• Production blockchain-integrated systems, wallets, indexers, and crypto payment/ramp platforms
• Large-scale performance optimization (including reducing heavy operations from minutes to seconds through batching, caching, and server-side optimization)
• AI-assisted engineering workflows and automation systems
• OCR-powered mobile utility systems with offline sync support
• UI/UX systems, dashboards, operational tooling, and responsive interfaces
• Long-term freelance illustration, game UI design, and creative asset production since 2018

Some notable experience includes:
• Shipping and scaling crypto ramp systems with multi-currency support, automated workflows, admin tooling, and transaction monitoring
• Building wallet, gifting, transaction, and account-management systems across desktop and mobile
• Contributing to blockchain indexing infrastructure and improving throughput/reliability for production environments
• Designing and implementing security-focused systems, safer auth flows, and operational safeguards
• Creating full RPG-inspired portfolio experiences with custom UI systems and responsive frontend architecture

I’m highly organized, fluent in English (CEFR C1), and experienced with remote collaboration tools including Slack, Notion, Trello, GitHub, and Google Workspace.

I’m open to:
• Full-Stack Development
• Frontend or Backend Engineering
• AI-assisted tooling and automation projects
• UI/UX-focused product development
• Creative and technical hybrid roles

I value clean engineering, thoughtful architecture, maintainable systems, and practical AI usage that enhances development rather than replacing engineering judgment.

I’m a fast learner, reliable, adaptable, and comfortable working independently or across teams.

Let’s build something meaningful together.
