About

Professional summary

I am a Senior Software Engineer with 8 years of experience in software development, primarily using C++. I specialize in building secure, scalable, and reliable systems where performance and efficiency are critical.

I have extensive experience with concurrent systems, multithreading, real-time communications, networking, and cross-platform development. My work includes improving latency, data handling, and resilience in high-scale cloud environments.

I have contributed to cloud storage and communication products serving more than 300 million users. In particular, I worked on WebRTC-based video calling, cryptographic protocol improvements, and file deduplication solutions.

I am comfortable working in security-critical environments and collaborating on architecture decisions, system optimization, and complex technical problem-solving. I use Agile practices including Scrum and Kanban.

Earlier in my career, I worked in systems administration across Linux and Windows environments, supporting enterprise infrastructure, incident response, monitoring, and service continuity. I also have experience developing PHP web applications and optimizing relational databases.
