Mariana K.

Customer Success & Operations Specialist | SaaS, AI, Onboarding

Customer Success, Operations, and Client Communication specialist with over 12+ years of experience helping international companies support clients, organize workflows, improve communication, and keep projects moving in remote environments. I’ve worked across SaaS onboarding, Account Management, Customer Success, sales support, operations, project coordination, and research/writing. My strength is being the person who brings clarity, follow-up, and structure without making things more complicated than they need to be. Expertise: Client Success & Onboarding: I manage client relationships, onboarding calls, training, follow-ups, feedback, and retention-focused communication. I’m especially strong at helping clients feel informed, supported, and confident. Operations & Project Coordination: I organize messy workflows, create SOPs, track deliverables, coordinate with internal teams, and make sure nothing falls through the cracks. Business Communication: I write and refine professional emails, proposals, reports, training materials, client updates, and internal documentation in clear, natural English and Spanish. AI-Assisted Workflows: I use tools like ChatGPT, Claude, Gemini, and Perplexity to support research, documentation, SOPs, content drafts, summaries, and communication workflows. I’ve also worked on AI-related projects with Outlier. Research & Content: I have written 200+ psychology and wellbeing articles and can support research, evidence summaries, qualitative analysis, and high-quality content creation. My background in psychology, law, and mediation gives me an extra layer of judgment, empathy, precision, and discretion, especially when working with clients, founders, senior stakeholders, or sensitive topics. I’m organized, proactive, reliable, and comfortable working independently with remote teams. If you need someone who can combine client care, operational structure, strong writing, and real ownership, I’d be happy to help.
