About

I’m a Web3 and AI-focused fullstack developer who enjoys turning complex ideas into simple, fast, and trustworthy products. Over the last few years, I’ve gone from building dynamic form systems and marketing sites to shipping real-world asset marketplaces and AI-powered mobile apps.

Today, I focus on leading small frontend teams, designing clear architectures, and iterating quickly with real user feedback — whether that’s guiding users through crypto onboarding for RWA marketplaces, or giving people a better way to talk about their relationships with SocialXray’s AI guide. I’ve led teams to ship mobile apps in about three months.

Experience

Case Studies

• SocialXray — AI Relationship App

  Fullstack Developer (AI focused) · Feb 2025 – Present

  SocialXray is a mobile app that helps people talk through their relationships with an AI guide, combining conversations with curated tests and reflections.

  Problem

  Ship an AI-powered relationship coach to both app stores quickly while keeping model costs under control and responses helpful and safe for users.

  My role

  • Led the frontend team using Expo/React Native from zero to launch.
  • Worked closely with product and AI engineers on flows, prompts, and user journeys.

  Challenges

  • Balancing response quality, cost, and latency for a conversation-heavy app.
  • Designing prompts and flows that stay useful across a wide range of relationship topics.

  Solution & impact

  • Launched on both Android and iOS, reaching over 5,000 users in the first week.
  • Optimized token usage by 50%–70% with better prompts and context handling, improving performance and privacy.
  • Set up a cadence of weekly releases, folding real user feedback into new features and refinements.

• Aconomy — RWA Trading Web & Mobile

  Web3 Frontend Developer · Sep 2024 – Present

  Aconomy is a real-world asset marketplace that lets users tokenize, trade, and manage assets across web and mobile interfaces.

  Problem

  Extend an existing Web3 RWA web app into a mobile app with more features and a better user experience under tight timelines and with evolving tooling.

  My role

  • Led the frontend team across web and mobile, owning key UI pieces for both experiences.
  • Helped new team members ramp up on the stack and codebase.

  Challenges

  • Web3 onboarding tools that worked on web did not translate well to mobile.
  • Compliance and licensing constraints made app store approvals difficult.

  Solution & impact

  • Guided the team to build a mobile version of the RWA app in about three months with Expo/React Native.
  • Iterated on multiple onboarding and wallet providers to get a decentralized flow that felt straightforward for users.
  • Strengthened the frontend architecture so web and mobile experiences could evolve together.

• The Tarzan Way — Configurable Form System

  Frontend Developer Intern · Sep 2020 – Dec 2020

  The Tarzan Way is a travel company that needed to launch new campaigns and booking flows quickly without rebuilding every form from scratch.

  Problem

  Creating custom interactive forms for each campaign was slow and repetitive and risked breaking the brand experience.

  My role

  • Designed and built a React-based form system driven by simple configuration.
  • Worked closely with the team to ensure new forms felt on-brand and easy to use.

  Challenges

  • Translating flexible JSON into reliable UI components with good defaults.
  • Doing this as an intern while learning React in a production context.

  Solution & impact

  • Reduced the time to create new forms by 40–50% compared to the previous approach.
  • Powered a Christmas campaign form that allowed users to book discounted travel packages, earning positive feedback from senior teammates.

Skills

Leadership & Approach

I enjoy leading small, focused teams and building products in messy, fast-moving domains like Web3 and AI. A lot of my work sits at the intersection of frontend, product, and architecture.

• Coach and onboard new frontend developers so they can contribute meaningfully in a short time.
• Lead teams to ship new products (often web and mobile) in roughly three months, with a bias toward iterative delivery.
• Use metrics like time-to-deliver, token usage, and user feedback to guide technical decisions.
• Stay comfortable working with evolving standards, tools, and constraints in Web3, compliance, and AI.
