Full-Stack Engineer · Web3 Infra · AI Workflow Automation

I’ve spent 6 years building infrastructure, automation, and mobile experiences across crypto, SaaS, and AI. I don’t just write code — I solve engineering problems most people avoid. I love turning constraints into elegant systems. And if something seems impossible — that’s usually where I start.

Selected Projects

Tiexo NFT Marketplace

An NFT analytics and marketplace platform that support real-time tracking across 10+ blockchains. This includes complex analytics, mobile dashboards, and performance that could match $100M+ competitors — all with a small team.

  • Helped design backend flow for real-time data processing and aggregation
  • Created native iOS and Android widgets inside an Expo app -- without ejecting -— using Swift, Kotlin, and custom plugins
  • Developed custom Expo modules to inject native code without ejecting the app
  • Collaborated on frontend dashboard UI
Impact:

✅ Enabled real-time tracking of 500K+ transactions/day across 10+ chains
✅ Delivered home screen widgets with live NFT metrics on iOS and Android
✅ Created systems that supported marketplace and dashboard functionality without 3rd-party APIs
✅ Contributed to a platform with cross-chain reach and native UX most Web3 apps couldn't match

Sui Analytics

The Sui analytics tool tracks project activity, token usage, and contract engagement in real time on the SUI blockchain — with an intuitive dashboard interface and fast data exploration UX.

My Role:

  • Developed the frontend dashboard UI in Next.js, with dynamic filters and activity breakdowns
  • Designed interfaces for token insights, transfer tracking, and leaderboard views
  • Assisted backend team with schema design and data normalization structure for efficient queries
Impact:

✅ Delivered a user-facing dashboard used to track activity across dozens of Sui projects
✅ Translated raw blockchain data into actionable insights for end users
✅ Helped shape backend structure to optimize frontend rendering performance

Moonlet Docs

Built a custom AI-powered documentation assistant using n8n + LangChain. It reads and answers user questions based on the latest Moonlet docs — a plug-and-play chatbot that trains on any structured content.

CaribeScout Ongoing

Full-featured real estate platform covering all Caribbean countries. Users can search listings, filter by region, and contact sellers directly. Agents can sign up, manage profiles, and list properties with full control. Built from scratch with dynamic search, multi-country support, and integrated inquiry flows.

AuditForge Ongoing

AuditForge automates SOC2 and ISO 27001 compliance by ingesting logs from AWS, GCP, GitHub Actions, and more — then uses AI to map findings to controls, detect drift, and generate PDF/CSV checklists and summaries.
