I run a small studio called EsperH — a one-stop shop for startups and product teams that need software that ships. Web apps, custom software, design systems, and infrastructure — the whole stack, owned by a small team that gives a damn.

• 🛠️ Senior fullstack — TypeScript end-to-end, from Postgres schema to CDN edge
• 🎨 Product designer — Figma → Tailwind, no friction; design that converts
• 🛡️ Security-conscious — OWASP-aligned, JWT/OAuth, rate limits, audit logs from day one
• 🚀 Ship in weeks, not quarters — lean delivery with weekly demos and shippable increments
• 🌏 Based in Indonesia · open to remote engagements globally

MERN (MongoDB · Express · React · Node) · PERN (Postgres · Express · React · Node) · TALL (Tailwind · Alpine · Laravel · Livewire) · T3 (TypeScript · Tailwind · tRPC · Next.js)

• Beautiful is non-negotiable. Every screen should pull its weight.
• Security at v1, not v100. OWASP defaults, not afterthoughts.
• Ship small, ship often. Weekly demos beat quarterly reveals every time.
• TypeScript end-to-end. One language, schema-first, zero context-switching tax.
• Own the stack. Postgres to CDN, design system to deploy pipeline.

I take on a small number of high-trust engagements each quarter. If you're building something interesting, I'd love to hear about it.
