À propos de Ian

I’m a full-stack engineer and solopreneur who’s been shipping real products since 2019—starting in technical SEO and WordPress/PHP, then moving into React/TypeScript, Node.js, Python, and cloud-native DevOps. I love taking ideas from zero to production, owning the messy middle (data, infra, performance), and delivering clean, maintainable code that users actually enjoy.

What I work with daily
  • Front end: React, Next.js, TypeScript, React Query, React Hook Form, Jest, React Testing Library, Cypress.
  • Back end: Node.js/Express, Python (Flask; adopting FastAPI patterns), REST/GraphQL, WebSockets.
  • Data: PostgreSQL/MySQL/SQL Server, MongoDB, Redis, SQL optimization, partitioning, materialized views.
  • DevOps: Docker, Nginx, CI/CD (GitHub Actions), AWS (ECS/Fargate, Lambda, API Gateway, S3, CloudWatch, Route53), GCP (Cloud Run, Scheduler, Pub/Sub), Terraform/IaC, secrets, IAM, cost-aware architectures.
  • AI: OpenAI, embeddings/RAG, LangChain, Pinecone, Whisper; classic analytics (EMA, anomaly rules).
How I can help

  • Build or refactor MVPs and dashboards.
  • Design scalable APIs and data pipelines.
  • Stand up cloud infra with Terraform/IaC, CI/CD, monitoring.
  • Integrate LLMs (chat, RAG, summarization, classification).
  • Technical SEO/performance audits to keep growth compounding.
