About

Professional summary

I am a Technical Customer Success Engineer and Technical Account Manager with more than 10 years of experience across software engineering, QA automation, enterprise support, and developer-tool adoption. I specialize in helping enterprise engineering teams implement and gain value from complex technical platforms.

I combine customer-facing technical consulting with hands-on engineering expertise in automation, APIs, cloud infrastructure, databases, and software development. I am experienced in conducting architectural deep dives, debugging integrations, resolving deployment blockers, and delivering technical onboarding and training.

In my current role at JetBrains, I lead Customer Success Engineering for EMEA, supporting high-value enterprise accounts and improving retention, adoption, and product feedback processes. I work closely with Product Management and Core Development teams to turn customer implementation gaps into actionable product insights.

I have managed large technical account portfolios, maintained strong customer-retention outcomes, and partnered with sales teams during renewals and expansion cycles. My work includes building proactive technical health checks, analyzing customer behavior signals, and coordinating escalations across cross-functional teams.

Earlier in my career, I led automation QA engineers and delivered backend test systems for high-volume API, billing, and payment platforms. I also provided tier-3 software support and developed Python and SQL automation for enterprise database and infrastructure environments.

I bring leadership, technical mentorship, Agile delivery, customer advocacy, and a practical problem-solving approach to technical customer success and account management roles.
