I build production-ready MVPs in 1–2 weeks.
MVP Engineer · Building at Buildberg
Web apps. AI agents. Internal tools. Whatever the wedge looks like for your idea.
Most founders spend months speccing v1. By then the market moved. I cut the loop — we agree on the wedge on a 30-minute call, you have something to push to users by the end of the next week.

How it works.
- 01
Day 0. 30-minute call. We agree on the wedge — the smallest thing that proves the idea.
- 02
Week 1. Core flow lands. Deployed, behind auth, with the one path that matters.
- 03
Week 2. Polish, payments if needed, handoff. You start showing it to real users.
- 04
After. Iterate weekly on what users actually do, not what we guessed.
Recent MVPs.
Mark
CTA widget management for blog posts.
One dashboard for the calls-to-action across every blog you've written. Swap, A/B test, and track without redeploying the site.
AdReel
AI UGC video generator.
Generate creator-style ad videos from a single product URL. Migrated from a Clerk/Cloudinary/Gemini patchwork to a fully open-source stack in one sprint.
FoxReach
Cold email outreach for AI agents.
Sender-rotation, warmup, sequence engine, and an API designed to be called by LangChain, CrewAI, and Claude agents — not just humans.
cold.md
An open spec for cold email — and a Claude Code skill.
Markdown-first sequences you can version, diff, and ship. Free skill for Claude Code, plugs into FoxReach. The marketing wedge that pulls people into the stack.

How a Clerk + Cloudinary + Gemini handoff became Better-Auth + MinIO + Kie.ai + BullMQ on a single VPS — without losing a working app along the way.

What I build.
-
Founder MVPs
Pre-seed teams that need v1 in users' hands now.
-
AI agent products
Agents that do real work, not chat demos.
-
Internal tools
The dashboard / portal / ops console you keep meaning to build.
-
Validation experiments
Landing page + working backend, ready for paid traffic in days.
The stack.
Next.js, Postgres, Better-Auth, MinIO, BullMQ, Docker on Hetzner. Claude + GPT for anything model-shaped. Cloudflare for the edge. I lean open source and self-hosted, because shipping fast and owning your data shouldn't be mutually exclusive.
Two weeks of building beats six months of speccing. Ship something users can poke. Then decide.
