End-to-end systems
From the first request to the last useful screen.
I turn ideas into working software.
Summary about me
Who I am and what I enjoy building.
Who I am.
Hi, my name is Cristian-Adrian Colăcel.
I am a computers and information technology engineer from Bucharest, currently studying for a Master's in Information Systems at University POLITEHNICA of Bucharest, after a Bachelor's in Computers and Information Technology at the same faculty.
I enjoy working close to the problem: learning how a system behaves, testing ideas, and turning rough experiments into software that is useful, understandable, and easier to improve. I like tinkering with unfamiliar tools, following a problem until I understand what is really happening, and then shaping the result into something I can explain, test, and keep improving.
What I enjoy building.
I enjoy building full-stack products with a backend orientation: services, data models, AI components, dashboards, and automation working together in a clear and usable experience. That balance lets me work across the product while still focusing on the systems, flows, and decisions that make everything reliable.
Applied AI / retrieval
Search, models, evaluation, and useful answers.
Data and telemetry
Turning noisy inputs into something people can use.
Automation and infrastructure
The small systems that keep the larger ones moving.
