I don't wait for the next wave. I'm already building on it.

Every wave runs
on solid infra.

Before the frontend, before the contract, before the agent — there's the system that makes it all work. Backend architecture, databases, queues, deployments. This is what I build everything on.

API & Service Architecture

Core Discipline

NestJS and Express APIs powering real-time applications. Session management, data aggregation from multiple sources, WebSocket integration, Bull queues for async processing. REST and GraphQL interfaces.

Real-timewebsockets + queues

Data & Storage

Core Discipline

PostgreSQL for relational data, MongoDB for documents, Redis for caching and pub/sub, Supabase for rapid prototyping with auth and real-time subscriptions. Data modeling across SQL and NoSQL systems.

Cloud & DevOps

Core Discipline

AWS (EC2, S3, RDS, Lambda), Railway, Vercel for deployment. Docker and Kubernetes for containerization. GitHub Actions CI/CD pipelines. Multi-environment deployment standardization.

Smart contracts.
Real money.

Self-taught Solidity before most people had heard of DeFi. Deployed contracts across Ethereum, Optimism, and Arbitrum. Built wallets, stablecoins, and cross-chain systems.

Agents.
Automation.
What's next.

Building AI agent architectures, RAG pipelines, and production automation systems. Same pattern — see the wave early, go deep, ship before the crowd arrives.

AI Agent Systems

Builder & Architect

Designing and shipping AI agent architectures with LangChain and LangGraph. RAG pipelines with Pinecone vector search. Production-grade n8n automation workflows connecting AI to real-world systems.

The skill isn't mobile or web3 or AI.
It's the foundation underneath — and knowing where to build next.

// three waves. each time: early entry, deep execution, real products, real users.

// work_with_me

Let's build
something real.

Technical Leadership

Fractional CTO, architecture reviews, team scaling. I set the technical direction and make sure it ships.

Mobile Development

Native iOS/Android, React Native. Greenfield to app store to millions of users.

Web3 & Contracts

Solidity, DeFi integrations, protocol architecture. Contracts that handle real money safely.
