About

6+ years of experience as a Support Engineer and Associate Product Manager across SaaS and Blockchain platforms, operating at the intersection of Technical Account Management, product operations, and enterprise customer success. Core focus: building and scaling the operational backbone for Web3 and AI platforms, translating complex system behaviour into product decisions that improve the user experience. What I bring to every role: 1. Enterprise Customer Success & Account Management End-to-end management of enterprise accounts: onboarding, SLA adherence, escalation management, and renewal confidence. At GeneiCloud, reduced P1 MTTR by 57% and cut support ticket volume by 11% through improved API documentation and cross-functional collaboration with engineering. 2. Product Operations & Roadmap Influence Responsible for the full product lifecycle feedback loop between users and engineering. Support trends get translated into data-driven product roadmap inputs, prioritised within Agile delivery frameworks. At Polygon, stakeholder management spanned 45+ enterprise validator operators, with technical insights fed directly into protocol governance decisions. 3. Infrastructure Reliability (SRE) Managed critical node operations for Polygon and Oasys on AWS and GCP, achieving 97% uptime. CI/CD, Docker, Grafana, and Datadog form the core observability stack. Also led RLHF initiatives to improve LLM accuracy for enterprise AI models. The differentiator is the hybrid background. Most TAMs come from support or sales. Most APMs come from pure product. This background spans distributed infrastructure, developer community leadership, and co-authored validator economics research across five major Blockchain networks. That depth means fluency with both the enterprise client in the boardroom and the engineer in the incident channel. Actively targeting roles at SaaS or Web3-native companies where technical expertise, customer success, and product thinking need to live in the same person.
