Technical Director of Mobile Engineering at Rostelecom Information Technologies
Valentin Telegin
Council Member
Valentin Telegin is the Technical Director of Mobile Engineering at RTK IT (Rostelecom), bringing over 20 years of experience architecting and scaling high-load mobile platforms for audiences of millions. Based in Moscow, Russia, he has built and led engineering organizations from the ground up, shaped cross-platform mobile strategy at one of Russia's largest technology holdings, and established engineering practices that have measurably accelerated delivery and reduced costs at scale.
In his current role at RTK IT, where he has served since 2019, Valentin Telegin directs the full scope of mobile engineering across the Rostelecom technology group. He built the department from scratch, growing it to over 100 engineers spanning iOS, Android, Flutter, Kotlin Multiplatform, backend, QA, DevOps, and engineering management. He transferred mobile development from external vendors entirely in-house, improving both delivery speed and code quality. Under his architectural leadership, the flagship application "Moi Rostelecom" grew to over 4 million monthly active users, while he also launched and scaled "Smart Home" to over 300,000 MAU and "Klyuch" to over 250,000 MAU. He designed and implemented a cache-first architecture with predictive prefetching that achieved interface response times under one second while reducing backend load and maintaining stability under peak demand. By introducing Kotlin Multiplatform and Flutter across the organization, he reduced development costs by up to 50%, and a component reuse strategy further cut costs on standard development tasks by up to 75%. Automation and CI/CD implementation reduced time-to-market by 50% and brought the release cycle down to two weeks. He also established unified Agile processes — including daily stand-ups, planning poker, and retrospectives — and designed a structured hiring framework that enabled the team to scale efficiently.

Prior to Rostelecom, Valentin Telegin served as Head of Mobile Development at Superjob from 2017 to 2019, where he managed end-to-end iOS and Android development for one of Russia's largest online recruitment platforms. He restructured development processes across multiple mobile teams, accelerating task delivery by 20%. He introduced a modern technology stack including Clean Architecture, Kotlin, Rx, and Room, and implemented a CI/CD pipeline using TeamCity, Docker, Artifactory, and Bitbucket that cut build and release delivery times significantly.
From 2014 to 2017, he led Android development at ABBYY, the international technology company whose products reach over 50 million users across more than 200 countries. He directed the development of Lingvo Live, a social language-learning platform that went on to win the prestigious "Zolotoye Prilozheniye" (Golden App) award. By standardizing architecture and implementing code and library reuse across ABBYY's mobile products, he increased the release rate of new functionality by 50% and reduced time-to-market by 25%.
Before ABBYY, Valentin Telegin built the Android development practice at Undev from 2011 to 2014, hiring and mentoring the team, delivering products including a video player, a conference application, and mobile games, and accelerating product releases by 50% through the standardization of shared components such as authentication, settings, and data storage.
Earlier in his career, he spent four years at Yandex from 2007 to 2011 as a Senior Software Engineer, where he developed the first mobile version of Yandex Maps — one of Russia's earliest mass-market mobile navigation services — and created the real-time traffic data processing algorithms that would eventually inform services used by over 35 million users. He also built core components of Yandex's mobile mapping platform. His professional origins trace back to 2004, when he spent several years developing mobile games and multimedia applications on J2ME and Symbian platforms.
Valentin Telegin is a member of the program committees for Mobius, the largest mobile developer conference in Russia, and CrossConf, the largest annual conference on cross-platform development. He has spoken at CodeTalks and Asterconf as well, and has served as a judge for the Premiya Runeta, Zolotoye Prilozheniye, and Tech Impact Awards. He has judged AI hackathons since 2019, including Digital Breakthrough, and serves as a reviewer of scientific and technical publications in the field.
