We build backend systems, full-stack products and AI features, and we run them in production.
COGITO CODE is a founder-led software engineering company in Bucharest, founded in 2023 by Jamil Zaitouny.
, therefore. The name COGITO CODE is a nod to Descartes’ cogito, ergo sum, “I think, therefore I am”. In our mark, two round dots are the premises and the conclusion is a square: a pixel, a block of code. Thought that resolves into something built.

01Services
What we build.
Backend and platform engineering
Services and event-driven systems on the JVM and in Python, with resilient integrations between them.
Full-stack product builds
Web products built end to end, with React and Next.js front-ends on top of our own APIs, and cross-platform mobile with Flutter.
AI and LLM integration
Retrieval over your own documents, with answers that link back to their sources, on self-hosted open-weight models or AWS Bedrock.
We are also building a product of our own: a booking tool and marketplace for independent photo, film and podcast studios, starting in Cluj-Napoca. It is pre-launch: the web app runs in production, and the iOS and Android apps are not yet in the app stores.
02Track record
What the founder has built.
Systems Jamil Zaitouny has built. They are his track record, not COGITO client engagements.
Low-latency trading connectivity
At Broadridge Trading and Connectivity Solutions, Jamil built the low-latency gRPC bridge between a high-touch trading solution and a high-frequency trading market-data platform, in Kotlin and Java, and owned the React trading terminal.
Secure knowledge aggregator and multi-agent platform
For a global automotive group, Jamil led a team of 3 engineers building a secure RAG knowledge aggregator, first on a self-hosted open-weight model for data compliance, then on AWS Bedrock. It grew into a multi-agent platform.
Event-driven microservices platform
For a European employee-benefits group, Jamil has built services on its Java and Spring Boot platform, with Kafka events, third-party API and CRM integrations, and consent and compliance flows.
