Ask HN: Freelancer? Seeking freelancer? (July 2025)
Please only post if you are personally looking to hire a freelancer or work as one. Agencies, recruiters, job boards, and so on, are off topic here.
Senior Frontend Engineer — I help startups ship fast and stay focused
10+ years building web products from scratch, often with small teams and directly with founders.
· Co-founded Movieo.me — 10K users in week one, front page of Product Hunt
· At Glean.ai, launched first revenue features and supported Series A
· At SolarisBank, built a frontend framework that cut dev time and sped up onboarding
Remote-first (was onsite in SF & Berlin). I focus on UX, delivery, and working independently. Open to full-time or part-time roles. If you need someone to own the frontend and move fast, I'm happy to chat.

Hi HN! I'm a full-stack developer with a strong frontend focus - 10+ years of experience building fast, clean, and scalable web apps.
On the frontend, I work with React, Vue, and Svelte. On the backend, I've shipped systems using Go, Python, and Node (Nest.js, Django, FastAPI, etc). I enjoy working on thoughtful product design and efficient APIs just as much as hacking on UI.
Lately I've been freelancing through ainurhq.cloud, doing both client projects and internal tools. Some recent work includes:
● jsDelivr: contributed engineering support and improvements
● Radiabase: contributed to a CRM-style lead and sales management platform
● UniDeck: a no-code, plug-and-play dashboard builder with built-in integrations. Built from the ground up with my team at AinurHQ
I'm currently looking for freelance/contract roles (or possibly full-time) - ideally on a modern product team where I can contribute across the stack.
Feel free to reach out if you're building something interesting:
