Hire the Best TeamViewer Specialists
in Ukraine

Customer Success Engineer with 12 years across technical support, integrations, and web development. Currently the sole CS owner at an AI support-automation startup — single point of contact for 8+ clients, first responder on every technical issue, and a direct contributor to the codebase. I sit in the gap most teams leave open: the person who can hold the customer relationship and also read the stack trace, write the fix, and ship it. SUPPORT OPERATIONS I run support as a system, not a queue. Setting up and tuning helpdesks in Zendesk, Intercom, Front, and Pylon — macros, triggers, automations, SLA policies, routing rules, tagging taxonomies, and reporting that shows where volume actually comes from. Platform migrations, knowledge bases from scratch (I wrote one company's entire customer KB in my first two weeks), and deflection content that measurably cuts ticket load. PAYMENTS & BILLING Hands-on with Stripe and Solidgate: subscription lifecycle, plan and metering logic, webhook handling, failed-payment and dunning flows, refunds and chargebacks, reconciliation against internal records. I've traced billing bugs end to end — from the customer's report, through the webhook payload, to the code path that dropped it. INTEGRATIONS & AUTOMATION Building the connective tissue between systems: REST APIs, webhooks, OAuth, retry and idempotency handling, event routing. I've debugged and fixed webhook routing failures, duplicate message delivery, and race conditions in live production. Custom workflow automation where off-the-shelf tooling runs out. MONITORING & PRODUCTION Log and trace analysis, SQL against Postgres/Supabase for health signals and root-cause work, proactive churn-risk monitoring instead of post-mortems. Shipped 8–9 production releases in three months; one deploy cut system errors ~99.7%. HOW I WORK Autonomously. I investigate before I ask, come back with findings and a proposed fix rather than a list of questions, and document what I touched so the next person doesn't have to re-derive it. Good fit if you need: support ops built or cleaned up, a billing integration that keeps breaking, customer-facing technical escalations handled properly, or one person who can own onboarding, integrations, and the engineering behind them.

For the past decade, I have been engaged in the Scaled Agile Framework, contributing to enterprise services in areas such as AI training and machine learning, particularly in data annotation and training intelligent bots to extract accurate, consistent data that aligns semantically with schema definitions and requirements; Knowledge Graph management - encompassing data entry, integrity assurance, and reconciliation. However, it is only 4 years that I have operated as a Contributor Lead, a role that, in this complex enterprise structure, encompassed responsibilities equivalent to project management, excluding budgeting. Nevertheless, I indirectly influenced budgeting by determining and assigning contributors based on expertise level (and, therefore, rates), urgency, project complexity, and budget constraints. I assessed client requests, evaluated feasibility regarding target dates, and engaged in service request discussions, providing references such as team capacity, throughput, and task distribution. Other than that I oversaw the performance and quality metrics of the team, ensuring that contributors meet their targets and deliverables with consistency and accuracy.

Hi, I’m Yaryna! I’ve been passionate about delivering top-notch service as a Project Coordinator, Customer Success Specialist, and Scrum Master. After obtaining a Master's degree in Economics and graduating from university in 2011, I started my career as an Accountant at Nestlé. Then, I took on the role of a Quality Assurance Specialist. Working in multicultural teams, learning from, and implementing the best practices of this global company, expanded my professional skill set. I then spent six valuable years at Veeva Systems, where I was promoted from Researcher to Data Quality Controller and finally to Operational Team Manager, leading a team of more than 30 research freelancers from around the world. In this role, I hired and trained new team members, tracked and improved performance and quality KPIs, and successfully increased team speed without compromising quality, which helped save the company costs. Next, I joined LoftyWorks as a Customer Success Specialist, where I became the first point of contact for customers. I was trained in property management, helping manage relationships with agents, landlords, contractors, and tenants. My daily responsibilities included keeping property management software up-to-date, onboarding new customers, arranging demo meetings, and setting up client data in the system. I provided product assistance and support, reported issues, and helped troubleshoot any problems. As a Customer Success Specialist, I was later promoted to the role of Scrum Master, where I led a rapidly growing international development team of 30 developers from China and Europe. In this capacity, I successfully managed both roles, continuing to support new customers while leading the team. My experience managing teams at Veeva Systems helped me transition smoothly into this role. As Project Coordinator, I facilitated Agile meetings, worked with Product Managers on backlog planning and prioritization, and made sure things moved forward without any roadblocks. I also tracked key metrics, reported on team progress using Jira and Confluence, and provided updates to the CTO. A big part of my job was ensuring that communication ran smoothly, despite the team being spread across different cultures and time zones. I worked to ensure that interactions were clear and precise, tasks were completed correctly, and deadlines were met. Additionally, I was responsible for gathering client-reported issues, addressing them with the development team, and making sure they were fixed in a timely manner to keep clients satisfied. I'm proud that I helped build a strong, self-organizing team and created a workflow that worked for everyone. By staying focused on deadlines and solving problems quickly, I ensured that stakeholders' and customers' expectations were always met. I'm happy to connect and chat about how I can bring my skills and experience to your team!
