Frontend systems
Interfaces that stay sharp as the product grows.
My default lane is typed, component-driven frontend work with enough structure to scale without feeling rigid.

Bucharest-based, shipping globally
Full-stack development for ambitious digital products
I build digital experiences that feel clear, fast, and impossible to ignore.
I'm Catalin "cLu" Stroe, a full-stack developer blending product thinking, motion, and modern frontend engineering. I help founders and teams turn ambitious ideas into polished sites, dashboards, APIs, and full-stack products that people actually enjoy using.

Direct collaboration, fast iteration, and a strong bias toward shipping work with character.
Current focus: full-stack product builds, interaction-heavy marketing pages, dashboards, and cleaner developer-to-design handoff.

Fast without feeling rushed
Need a launch, redesign, or product surface that feels premium from the first scroll?
I build it at warp speed.
Strategy, layout, motion, and implementation in one loop, so the work stays sharp instead of getting watered down between handoffs.
Why teams hire me
Full-stack thinking first. Better interfaces, cleaner systems, and products that hold together end to end.
I care about structure as much as spectacle. That means sharper navigation, clearer messaging, stronger interaction states, and systems that still feel good once real users start clicking around.

Selected focus
Interfaces that feel alive, not overloaded.
The goal is never motion for its own sake. It is to guide attention, reinforce hierarchy, and make the product feel more intentional.

2024 to now
2024 to now
Focused on shipping sharper product surfaces: portfolio experiences, frontend systems, and full-stack applications with better pacing, hierarchy, and interaction quality.
Building modern Next.js frontends with stronger storytelling and cleaner UX.
Connecting UI decisions to APIs, backend logic, and the realities of product delivery.
Improving visual systems, motion, and implementation quality in the same workflow.
Working with teams that need speed without landing in generic template territory.
2023
2023
Went deeper into full-stack delivery, pairing frontend craft with backend services, integrations, and the kind of practical decisions that make products easier to ship.
- Built with React, Next.js, TypeScript, and backend tooling instead of treating the frontend in isolation.
- Learned where animation helps comprehension and where it just adds noise.
- Started shaping stronger opinions around structure, content, and product direction.
Earlier
Earlier
Started from curiosity, experimentation, and a lot of iteration. That foundation still shapes the way I work: keep learning, keep shipping, and keep raising the bar on the details.
Learning by building and rebuilding.
Exploring how design and code influence each other.
Developing the instinct to make products feel more intentional.
Core stack
Full-stack tools I rely on when the product needs both speed and staying power.
Less filler, more signal: typed frontend architecture, practical backend work, and data tooling that helps ship real features without making the stack feel bloated.
Backend and APIs
Application logic that supports the product instead of fighting it.
I build the backend pieces needed to keep the frontend fast, consistent, and easier to evolve.
Node.js
Python
Data layer
Pragmatic tools for auth, storage, and product data.
I reach for managed backends when they help teams move faster without turning the codebase into a workaround factory.

Neon DB
Mobile and native
Cross-platform and Apple-platform work when the product needs to leave the browser.
I can work beyond the web too, whether that means React Native for shared product logic or Swift and SwiftUI for Apple-native interfaces.

AI tools
I actively use AI tools as part of how I build, debug, and refine products.
This is part of my workflow, not an afterthought. I use AI tools to move faster, evaluate alternatives, and keep momentum high while still making the actual product decisions myself.
AI-assisted development
I use AI tools daily to accelerate implementation, explore options, and unblock research faster.
Prompted iteration
I use them to test approaches, draft structures, and tighten rough ideas before I commit them to code.
Code review support
They help me pressure-test edge cases, spot weak assumptions, and move through repetitive work with more speed.
Workflow multiplier
The point is not replacing judgment. It is shipping better work faster with stronger feedback loops.
