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.

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.

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.
Capability map
Four pressure points where the work gains clarity, pace, and stronger structure.
Selected pressure points
01
01Editorial pulse
Marketing sites with character
Sharper hierarchy, bolder pacing, and landing pages that feel authored instead of assembled.
02
02Operator clarity
Dashboards with a cleaner flow
Operational surfaces that reduce friction, quiet the noise, and guide the next decision faster.
03
03Production grade
Launch-ready Next.js builds
Polished frontends wired to real structure, sensible states, and production-minded implementation.
04
04Design x logic
Full-stack features with stronger UX
Interaction details that survive handoff because the design and the system are solved together.
Selected milestones
A few turning points that shaped how I approach product design, full-stack development, and modern frontend engineering today.
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
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.

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.

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.
