@olegbeloy
I build and scale secure Android products, SDKs, and international engineering teams.
PortugalWhat I'm looking for
At Point Wild, I lead the rebuild of an acquired Android antivirus SDK, owning its public contracts, product decisions, and full delivery lifecycle. I cut scan speed by 3× and helped raise detection rates from 25% to 99%.
Previously at Aura, I led Android engineering for internet security and identity-protection products used by more than 5 million people. I led a team of 10, delivered 200+ production releases, and owned roadmap and technical strategy across a portfolio of security apps.
I’ve led VPN SDK work across WireGuard, OpenVPN, Hydra, and IPSec; modernized apps from Java and RxJava to Kotlin, coroutines, and Flow; and advanced multi-module and Compose adoption. I also improved mobile health at Aura, cutting cold-start time by 50%, crash rate by 3×, and ANR rate by 2×.
Earlier at Wirex, I helped launch and stabilize its Android platform, moving a monolith toward a multi-module architecture and improving crash-free sessions to 98.5%. I value the positive impact my work can have on my team, company, and product users.
