# Clutch Developer > Clutch Developer — the product studio of Pedro Manfredi. Own apps, client work, zero fluff. Software engineer and indie product builder based in Barcelona. Twelve years shipping native mobile — Swift on iOS, Kotlin and Java on Android, Flutter when one codebase makes sense. Today I pair that experience with an AI-first workflow to build and ship around 10× faster than I could a few years ago — and I help teams do the same. I've also sat on the other side of the table. I founded VipKing in 2014 and spun out Pictus from it, went through Yuzz — Banco Santander's pre-accelerator — and NEXT, Powered by Google for Entrepreneurs, and have mentored startups since 2016. Since 2019 I've been tech lead on a native iOS app with over a million downloads at L+R in New York. So when a CEO and a CTO stop understanding each other, I've usually been both. ## Consulting - [Consulting](https://clutchdeveloper.com/consulting/): Ten ways to plug me into your team — from a first AI intro to full product delivery. - [Intro to AI](https://clutchdeveloper.com/consulting/intro-to-ai/): First session for teams and execs. - [AI adoption & rollout](https://clutchdeveloper.com/consulting/ai-adoption/): From tools to habits. - [AI product development](https://clutchdeveloper.com/consulting/ai-product-development/): LLM features that reach production. - [AI assistants](https://clutchdeveloper.com/consulting/ai-assistants/): A helper that knows your business. - [Native app development](https://clutchdeveloper.com/consulting/native-app-development/): 12 years of mobile. - [Websites](https://clutchdeveloper.com/consulting/websites/): Marketing sites that ship in days. - [Auditing](https://clutchdeveloper.com/consulting/auditing/): Know where your app really stands. - [10X delivery](https://clutchdeveloper.com/consulting/10x-delivery/): Startup speed, senior quality. - [Automation & integrations](https://clutchdeveloper.com/consulting/automation-integrations/): Your ops on autopilot. - [Cloud & backend](https://clutchdeveloper.com/consulting/cloud-backend/): The boring parts, done right. ## Pricing - [Product Audit — From €300 (1 hour)](https://clutchdeveloper.com/#pricing): A senior second opinion on what you already have — before you commit a budget to fixing it. - [Build Sprint — €7,500 (2 weeks)](https://clutchdeveloper.com/#pricing): Two weeks, one shippable outcome, a price agreed before we start. - [Embedded Partner — €6,000 (per month)](https://clutchdeveloper.com/#pricing): For teams who need a roadmap run, not a single deliverable handed over. ## Products - [Products](https://clutchdeveloper.com/products/): Live products from the studio — designed, built and shipped in-house. - [Luna](https://clutchdeveloper.com/products/luna/): AI bedtime stories where your child is the hero. - [Luna — Open the live site](https://lunastorytelling.kids): Luna is the studio's bedtime-story app for children around two to nine.
