Experience

  1. Founder & Full-Stack Developer | Orbitally

    – Present

    orbitally.tech (opens in a new tab)
    • Founded an independent web studio and, as sole developer, built and launched the Company Enrichment API (Node.js, Express, TypeScript, PostgreSQL) on RapidAPI with a free tier and paid plans; it turns a domain into a structured company profile with a 0–100 confidence score.
    • Engineered for reliability: request coalescing, two-tier caching with per-error lifetimes, proxy fallback and dead-lettered async writes, so the API still returns data when the LLM is down; Gemini structured output with micro-batching; load-tested with k6 on a 300-domain corpus.
    • Deployed in Docker on GCP behind Nginx with TLS; Neon PostgreSQL tuned to scale to zero when idle.
    • Built orbitally.tech (Next.js 16, React 19) with a live API playground secured by a server-side proxy, Cloudflare Turnstile, four Redis rate-limit tiers and masked data; 63 tests, CI, and 100/100/100 Lighthouse.

  2. Contract Full-Stack Developer | Bridginex (BezBroker platform)

    –

    bezbroker.com (opens in a new tab)
    • Hired by Bridginex, a European software firm, to build BezBroker, a real-estate marketplace, from their Figma design; owned the frontend and backend and worked with their team and project manager through launch.
    • Built the backend (Next.js route handlers, Prisma, PostgreSQL): 10-model schema, 25+ REST endpoints, search with cursor and offset pagination, favorites, and 1-on-1 messaging.
    • Implemented email/SMS OTP login (Brevo, Twilio) with HTTP-only cookie sessions, plus Cloudflare resumable video uploads with HMAC-verified webhooks and direct-to-CDN image uploads.

  3. Web Developer (Blog & CMS) | YICN Roofing

    –

    yicnroofing.com (opens in a new tab)
    • Built the blog platform for yicnroofing.com as part of a team (Next.js 15, Contentful): listing, dynamic post pages with static generation and ISR, and a custom rich-text renderer.
    • Added CMS-driven SEO (titles, descriptions, Open Graph and Twitter tags) so the owner can publish and optimize posts without a developer.
