Fuat Fucucuoglu

AI-Native Software Engineer

Fuat is an AI-native software engineer with more than six years of experience building products across startups. He works across the product and its underlying systems: the interface people use, the services behind it, and the data that makes it useful.

As the founder and lead engineer of UpHunt, he built an AI job-search platform with search, matching and background processing. His matching work combines OpenAI embeddings, a production vector database and custom ranking. He also built Qaft as an internal tool for UpHunt, bringing together LLM agents, public web data and real-time monitoring.

Before founding his own products, Fuat worked on cloud data infrastructure at Para, backend services at Konneka, and security research and backend development at PRISMA CSI. That background spans early product development and the practical work of keeping data, permissions, jobs and monitoring working together.

At Rosecraft, his focus is AI products, backend engineering and data systems. He brings experience taking SaaS ideas into working products, with attention to the business purpose as well as the implementation.

The studio

Close to the problem.
Responsible for the result.

You work directly with the engineer shaping and building your software. That keeps technical decisions connected to the business, and the conversation connected to the person doing the work.

We build software the way craftspeople build heirlooms — with intention, precision, and pride. Every line of code serves a purpose. Every architecture decision considers the long game.
The principles

Our values.

The principles that guide every line of code and every client relationship.

01

Craftsmanship

Every line of code is intentional. We build software the way artisans build furniture — with precision, pride, and an eye for detail.

02

Innovation

We stay at the frontier of web technology, bringing cutting-edge solutions to real-world problems without chasing hype.

03

Integrity

Honest estimates, transparent communication, and code we stand behind. No shortcuts, no surprises.

04

Results

Beautiful code means nothing without business impact. We measure success by the outcomes we deliver for our clients.

From the first conversation

How we work.

Our engagement process from first call to ongoing support.

  1. 01

    Discovery

    We listen deeply to understand your business, goals, users, and constraints. No assumptions — just questions and clarity.

  2. 02

    Design

    Wireframes, prototypes, and visual concepts that align with your brand. We iterate until the design feels right.

  3. 03

    Build

    Clean, tested, production-grade code built with modern technologies. Frequent demos and open communication throughout.

  4. 04

    Launch

    Rigorous QA, performance optimization, and a smooth deployment. Your project goes live with confidence.

  5. 05

    Support

    Ongoing maintenance, monitoring, and iteration. We treat launched projects as living products, not finished deliverables.
