Дмитрий Петрушин

I’m a Full Stack Developer with 5+ years of experience building AI-powered products across fintech, social intelligence, edtech, and healthtech. I focus on end-to-end product engineering—from frontend interfaces and backend services to APIs, data workflows, analytics, AI/ML integration, monitoring, and production support.

At Kaspi Kazakhstan, I developed AI assistant functionality for a high-scale banking super-app. I built full-stack assistant modules (chat/voice self-service, product navigation, support routing, and transaction-related scenarios), shipped 30+ production releases, and improved supported-flow response latency by ~35% through API optimization, caching, request validation, and asynchronous processing—while increasing self-service containment by ~20% and reducing operator escalation by 15–18%.

I also developed AiMap at KazDream Technologies, an AI-based service for monitoring social-media risks and digital signals for educational organizations. I integrated AI-enabled classification and data-processing workflows, reduced risk-review time by ~30–40%, lowered false-positive review workload by ~20%, and improved dashboard performance by ~35% using optimized queries, pagination, data validation, and better analytics views.

Beyond core roles, I’ve contributed to an AI education platform for tutors and online schools—cutting lesson-preparation workload by an estimated 40–60% and building analytics workflows for progress, weak topics, tutor activity, and retention. I’ve also supported MRI analysis software development for medical centers, helping clinicians review AI-assisted tumor detection and producing clinically usable result presentations.
