Senior full-stack & product engineer
From rough idea to production.
I work across product, frontend and backend. Bring me in when the problem is still rough or the product needs to move.
Based in Romania, working internationally. Open to remote contracts, freelance projects and EU-based roles, with working hours that overlap Europe and North America.
Where I am most useful
I am usually brought in for one of three situations.
An idea needs to become a product.
I help shape the scope, make the first technical decisions and build a version people can actually use.
An existing product is hard to ship.
I find the real blockers, reduce unnecessary complexity and help the team move again.
A live platform needs better foundations.
I improve the parts that slow delivery down without treating a rewrite as the default answer.
PROOF OF WORK
Selected work
A few examples of the product problems I have worked on. Client details are intentionally kept private.
01
AI and ML workflow platform
Helped build a visual platform for creating workflows and running models in the cloud. I worked across the React and TypeScript frontend, Java and Micronaut services, authentication, teams, roles, performance and a reusable UI library.
Improved the product's accessibility and performance while making the interface easier to extend.
02
AI application builder
Took an internal AI web application builder from a rough idea to a working MVP. I worked across the product flow, rendering system and services using Next.js, Node.js, Python and Java.
Made the building and rendering flow faster and ready for real internal use.
03
Commerce platform modernisation
Helping modernise a live commerce platform while it continues to serve customers. The work spans Next.js, TypeScript, Node.js, Supabase, MedusaJS, testing and delivery workflows.
Improved delivery speed and reduced the time spent waiting for CI.
More selected work
- Built a property-management mobile application with React Native and Expo.
- Joined an insurance product close to launch, fixed blocking bugs and improved fragile product flows.
- Built the first version of a mortgage-technology product used in client demonstrations.
- Worked on public-sector digital products used to move services away from manual processes.
ROUGH / ALIGN / SHIP
I stay close to the problem.
The job is not finished when the ticket is closed. I keep the product, the system and the people using it in view.
- 01Rough
Understand what matters.
I ask questions, map the constraints and reduce the idea to the smallest useful problem.
- 02Align
Make the decisions visible.
I connect product choices to technical choices so the team knows what it is building and why.
- 03Ship
Build, test and learn.
I work across the stack, put the product in front of real users and improve it from evidence.
AI-enabled delivery
AI is part of the workflow, not the pitch.
I use AI across planning, coding, testing, reviews and documentation. It speeds up the work. It does not make the decisions for me.
Over the past year I have worked in a small experimental product team testing AI-driven ways of working. That included MCP integrations, plugins, reusable skills, custom workflows and different approaches to product delivery.
We may be a good fit if…
- You need one senior engineer who can work across product, frontend and backend.
- The problem is not fully defined yet.
- You want practical use of AI without handing judgment over to a tool.
- You care about shipping, but not at the cost of a product nobody can maintain.
- Your team works remotely across countries or time zones.
I can take on international contracts and freelance projects, or join an EU-based team. I prefer substantial product work where I can stay involved long enough to own the outcome.
THE ENGINEER
About Alex
I am a senior full-stack engineer in Romania, and I work with product teams internationally. I like work with unclear requirements, systems that cross several layers and products that need someone to stay close until the job is done.
My background covers product development, frontend, backend, mobile applications and live platform modernisation. I work with teams across Europe and keep daily overlap with the US and Canada until 23:00 Bucharest time.
