Umeadi Callistus

I’m Callistus, a detail-oriented and tech-savvy professional based in Lagos, Nigeria, with strong native-level English fluency and a passion for clear, accurate communication. I hold a B.Sc. in Computer Science and have hands-on experience in computer maintenance, networking, and digital operations—from supporting JAMB registration systems to managing warehouse logistics with 100% accuracy.

My strength lies in listening carefully, solving problems methodically, and communicating clearly—whether I’m troubleshooting a software issue, transcribing spoken words with emotional context, or assisting a client through a complex process. I’ve worked remotely since 2023, managing freelance tech support and operational tasks with full reliability, discipline, and attention to detail.

I’m proficient in Windows and Linux (Ubuntu, Mint), Google Workspace, Microsoft Office, and basic terminal commands. I type accurately, follow instructions precisely, and take ownership of every task I handle. While I may not be the loudest voice in the room, I’m the one who ensures nothing falls through the cracks.

I’m especially interested in roles that value consistency over charisma—such as:

Remote Customer Support (IT/Tech focus)

Technical Operations Assistant

Transcription & Annotation (audio/video)

Data Entry & Digital Documentation

Junior QA or Process Improvement Support

I work from a quiet, dedicated home office with stable high-speed internet and am available for full-time (40 hrs/week) or part-time (20+ hrs/week) remote work, including night shifts to align with EU or US time zones.

I believe great work comes from humility, honesty, and care—not just speed or flair. If you need someone who shows up consistently, communicates clearly, and treats every task as a promise, I’d be honored to collaborate with you.
