Hi, I am
Vladimir Evgrafov
CTO of the viju streaming service. Researching LLM-agent security as a PhD student at MSU CMC.
About
I am the CTO of Viasat Tech, leading a 35-person technology department (7 teams: Web, iOS, Android, Smart TV, Android TV, Go Backend, and systems analysis) that builds the viju streaming service for web, mobile, and TV platforms.
A CTO with technical roots: I started as a Go developer and grew into running an engineering department. I am good at quickly figuring out what is going wrong technically — in architecture, processes, or the team — and building a system that works. I have built an engineering department from scratch, migrated legacy systems to microservices, and I own the department budget, cutting infrastructure costs without sacrificing quality.
My profile sits at the intersection of engineering leadership, architecture, and AI. I manage development, DevOps, and the ML track, working with recommender systems, LLMs, and AI agents. In parallel, I am writing a PhD thesis at the Faculty of Computational Mathematics and Cybernetics of Lomonosov MSU and publishing research on LLM agent security and attacks on language models.
Open to part-time and project engagements as a fractional CTO or technical advisor.
Experience
Viasat Tech — Chief Technology Officer (CTO)
Responsible for development, QA, infrastructure, architecture, and the AI track. In 2025: a hundred releases across 7 platforms, quarterly plan completion up from 40% to 83%, Android crash rate cut 14× (down to 0.17%), video start time halved, and a new product stream launched on all platforms simultaneously.
Viasat Tech — Head of Software Development
Second hire in the technology department: recruited 35 engineers, QA specialists, and analysts, and established the development processes. Designed and implemented a Go microservice backend — the service now sustains 100× the load at one quarter of the resource consumption.
Atlas Biomed — Backend Team Lead
Built a multi-service system for processing and interpreting medical data.
TRMPLN Media — Golang Developer
Developed a high-load, fault-tolerant ad serving system with a focus on safe handling of personal data.
Multy — Golang Developer
Built microservices for communicating with various financial systems.
Okmeter — Golang Developer
Worked on a monitoring service: agents collecting metrics from physical devices and individual processes on Linux.
SolidWall — Python Developer
Wrote and maintained the core Python codebase, built the software build and deployment system, and administered CI and monitoring.
Education
Lomonosov Moscow State University, CMC — PhD candidate
Thesis on the security of LLM-based agentic systems.
Lomonosov Moscow State University, CMC — MSc
Lomonosov Moscow State University, CMC — BSc
