Media Marketing & Creator Partnerships

From launching a 100K+ YouTube channel, to finding creators/brands to sign, to creating a fully automated workflow from script to voice to video using AI. I help handle everything — content, community, and the brand partnerships behind it. Roughly 1.5M followers across all accounts I've managed.

Influencer Growth & Creative Ops — A Priori Productions
May 2025 – Sep 2025  ·  Remote

James Leonidas

I ran every social media platform for a creator with a cumulative following in the seven figures: TikTok, Instagram, YouTube, Snapchat, X, and LinkedIn. Posting, editing, comment replies, and community management were mine day to day.

The piece I'm proudest of: the YouTube channel didn't exist when I started. I helped launch @JamesLeonidas from nothing, and used short-form content as a catalyst to grow the channel to 100K+. It's past 120K now.

I also handled the unglamorous stuff — assistant work, sitting on call with him reading scripts aloud, writing scripts from scratch, and brainstorming content ideas were a part of my day-to-day.

Creators Agency

Influencer Marketing, Social, & AI Production Intern
Jun 2026 – Aug 2026  ·  Austin, TX

Creators Agency

Ghostwrote for both Creators Agency and its CEO across LinkedIn and Instagram. I posted almost daily: comedy skits I directed and edited, creator-economy commentary I scripted, and daily comment and reply management.

The work I'm proudest of: an autonomous video pipeline for Trusted Stack's YouTube channel (25K+ subscribers), using ElevenLabs and HeyGen for generation and Claude agents and Codex for scripting and editing. Topic in, published video out — 7 completed videos shipped for the week in a few hours, cutting production time by days.

On the partnership side, I've produced Instagram content for Caleb Hammer, Ramit Sethi, and the Credit Brothers, and ran affiliate campaigns for SoFi, Public, and Yrefy.

DLG International

I grew and promoted nightlife events for Barcelona's international student community on Instagram and Snapchat, building the audience that decides where the city's nightlife spends its money.

I promoted events with EDM artists including Matroda, Ian Asher, and Sidequest at Barcelona's top clubs — Shoko, Sutton, and Pacha — converting online reach into physical turnout at DLG's luxury events.

Rutherford Media Partners

Creator/Brand Sourcing, Outreach & Partnerships Intern
Feb 2026 – May 2026  ·  Remote

Rutherford Media Partners

I sourced and vetted high-growth YouTube creators for brand campaigns — outreach through Apollo.io, performance audits through Gospel Stats. The job was deciding who was worth signing before anyone else: checking audience authenticity and real engagement, not just follower counts.

I also help with brand outreach — working through brand lists Rutherford provided, I was able to find brands that best fit creators on their roster.
