Work Experience
AI Software Architect
Toptal Client
- Architected multi-agent orchestration systems for engineering teams using a Rust workspace to coordinate Claude Code, Codex, and Gemini CLI as agentic workers in a single runtime.
- Developed a 15-crate Rust workspace that covers orchestration, distribution, and infrastructure integration, utilizing Tokio async, Tower middleware, and OpenTelemetry for observability.
- Deployed in a production environment on GCP Cloud Build and Kubernetes using rustls for TLS, with pre-commit gates enforcing Clippy, cargo-nextest, and more than 80% coverage before any code merges.
- Delivered signed CLI binaries to engineering teams, implementing prompt routing, agent state isolation, and hook-based guardrails to ensure multi-agent coding survives in production.

Yahoo Immersive
https://www.yahoo.com/immersiveOpenStreetMap-based Maps and Navigation Application
https://osmand.net/With a firm understanding that growth required multi-platform support, a new multi-platform C++-based core development was started. Initially, support for Windows Phone was considered as well, in addition to iOS, yet the platform died before the project fully supported it.
The rendering approaches in the legacy Java core and the new C++ core differed dramatically since the new core aimed to support 3D with the terrain. This imposed many challenges as it required a lot of device-specific OpenGL-related issues to be worked around.
We successfully achieved the goal of publishing OsmAnd to iOS and introducing 3D rendering with terrain support to the Android version of the app.

R&D on Real-time Motion Capture Integration with VR
We worked on the project's goal of delivering a proof-of-concept demo, yet the technology behind some components was too young to produce any commercial product at the time.

Android Operating System Adapted for Partnered Telecom Operators
The adaptation included a completely new Android Home design, bundling of regional applications, and custom firmware updates delivery.
The project was based on the system from one of Qualcomm's partners. It included various unwanted country-specific alterations like state-sponsored TLS root certificates, which posed a threat and required a full security audit to reveal those undocumented modifications.
