At CoinTR, I worked as an Information Systems and IT Support professional in a hybrid role, providing both on-site and remote support within a highly regulated fintech environment.

I delivered end-user IT support to internal teams, resolving issues related to Microsoft 365 applications, Windows 10/11 workstations, mobile devices, and collaboration tools. I managed Azure Active Directory user lifecycles, including account provisioning, license assignments, security and distribution groups, MFA support, and routine access audits.

I deployed, configured, and maintained laptops, desktops, and mobile devices using Intune and Autopilot, ensuring compliance with security baselines and configuration profiles. I also managed ICT asset inventories, prepared devices for issuance, tracked allocations, and supported onboarding processes in coordination with HR and relevant units.

I supported users in effective use of Microsoft Teams, SharePoint, and OneDrive, assisting with permissions, shared drives, document collaboration, meeting setups, and storage compliance. In addition, I provided ICT support for meetings, conferences, and hybrid events, ensuring reliable hardware, connectivity, and video conferencing setups.

Alongside IT operations, I was responsible for technical operations, system integrations, and audit readiness in a highly regulated fintech environment. I tested web and mobile applications, identified functional and technical issues, and prepared detailed issue reports.

I resolved user-facing issues in withdrawal and deposit processes by performing SQL database queries, analyzing Kibana logs, identifying API-related transaction failures, and implementing corrective actions.

I technically managed end-to-end integrations including MKK API, KPS, Travel Rule, and Custody systems, covering demo environment setup, Postman-based REST API testing, execution of test scenarios, and validation of regulatory compliance and operational reliability.

I also assumed technical responsibility during SPK, MASAK, internal, and independent audits, preparing technical explanations, validating system workflows, supporting evidence generation, and coordinating with internal teams and external service providers.

In parallel, I developed automation tools for Fraud and Compliance teams, reducing manual operational workload by approximately 80% and significantly improving process efficiency. I actively participated in ICT meetings, maintained technical documentation, and contributed to the continuous improvement of IT, security, and operational processes.
