Building Digital Experience Analytics (DEA) within Splunk Observability Cloud - a platform correlating APM data with product analytics to surface customer behavior insights.

• Led integration of DEA data into the Splunk AI Assistant, acting as domain point of contact and collaborating with product, frontend, and AI teams to design query semantics for natural-language analytics exploration
• Designed AI-facing APIs and schemas (GraphQL over Java REST services) to make complex analytics data reliably consumable by LLM tooling
• Implemented MCP-based function calling and prompt optimizations to improve correctness and relevance of AI-generated analytics answers
• Designed and deployed cloud-native backend services on Kubernetes, including CI/CD pipelines and observability

Worked on Cisco AppDynamics, an APM platform for cloud and hybrid environments. Focused on a new storage model powered by OLAP databases.

• Evaluated and load-tested OLAP databases (ClickHouse, Druid, Pinot) for multi-terabyte event storage; delivered PoC reducing query latency by ~60%
• Contributed to design of a new analytics storage model used by core AppDynamics workflows
• Implemented remote configuration system for web and mobile SDKs, enabling dynamic behavior changes without app releases across hundreds of enterprise customers
• Mentored two backend teams on Node.js best practices, testing, and developer tooling

Worked on a large-scale user behavior analytics platform processing events, sessions, and crash data.

• Built session analytics APIs aggregating high-volume event data from Elasticsearch
• Developed anti ad-block proxy solution, recovering ~20% of previously blocked tracking data
• Developed crash reporting service handling 1M+ mobile crash events monthly (iOS & Android)
• Maintained RBAC and auth system supporting 400k+ users
• Improved CI/CD pipelines in GitHub Actions, reducing build times by ~30% and improving developer feedback loops

Designed and delivered fullstack systems and infrastructure for small and medium businesses, with focus on automation, integrations, and cost-efficient cloud architectures.

• Built reservation system with Telegram bot and email automation (500+ monthly bookings)
• Developed CRM with Apple Wallet passes and Dotykacka POS integration
• Migrated 5+ legacy web applications to AWS, reducing hosting costs by 60%
• Designed and deployed 10+ smart home networks (UniFi, Home Assistant)
