I'm a Senior Software Engineer with 6+ years specializing in mobile and full-stack development. I tackle challenges others avoid — from creating a custom Android ROM to resolve deployment conflicts to building real-time communication plugins when third-party solutions fail, I’ve helped rescue enterprise projects from client loss. I led a company-wide AI transformation initiative and am security-focused, proactively discovering vulnerabilities before external audits. I’ve scaled production applications from 10K to 50K+ users and maintained systems serving 130K+ users, all while mentoring teams and driving architectural choices.
