Capabilities

Four areas, one engineer.

    • Next.js App Router (SSG, ISR, server components)
    • React 19, TypeScript
    • Tailwind CSS, design tokens, dark mode
    • Accessibility, SEO, Core Web Vitals

  • Backend & Cloud

    APIs and infrastructure that stay up and stay clear.

    • Node.js, Fastify, Express, Laravel
    • AWS Lambda, Cognito, SQS, S3
    • PostgreSQL, MongoDB, Redis, BullMQ
    • Docker, Azure DevOps CI/CD, Entra ID

    Useful AI features with sources, guardrails and fallbacks.

    • RAG with pgvector and citations
    • OpenAI, Claude and Gemini APIs

  • Mobile & TV

  • 01

    Static by default

    Every page is prerendered at build time. Case studies use generateStaticParams, so there is no server work per visit.

  • 02

    Accessible

    Skip link, semantic landmarks, visible focus states, keyboard-first navigation and full reduced-motion support.

  • 03

    Typed end to end

    TypeScript in strict mode, one typed content file drives the pages, sitemap, metadata and structured data.

  • 04

    Search-ready

    Per-page metadata, canonical URLs, JSON-LD (Person, WebSite, CreativeWork), a real sitemap and generated Open Graph images.

  • 05

    Lean JavaScript

    No animation or 3D libraries. Motion is CSS and a few lines of IntersectionObserver. Fonts are self-hosted by next/font.

  • 06

    Hardened contact API

    zod validation, honeypot field, per-IP rate limiting, HTML-escaped notification emails and security headers on every route.
