Most teams only discover their AI agents' critical failures after silent token burns, hallucinations, or lost user trust in production. I build the infrastructure and verification layers that catch these issues before they scale.

Available 30+ hours per week. If you need robust Python AI agents, MCP infrastructure, RAG systems, or production-ready agent tooling that actually works at scale — send me a message.

I help creators and brands turn raw footage into clean, engaging videos that keep viewers watching. I work mainly with YouTube videos and short-form content (Reels, TikTok, YouTube Shorts). My focus is simple: good pacing, clean cuts, clear storytelling, and edits that feel natural — not overdone. Here’s what I can help you with: - YouTube video editing (long-form & short-form) - Reels, TikTok, and Shorts editing - Cutting, trimming, and pacing improvements - Adding subtitles/captions - Basic motion graphics and text animations - Sound cleanup and background music - Simple color correction I understand that every creator has a different style, so I follow references closely and communicate clearly before starting. Whether you want fast-paced short content or clean, distraction-free YouTube edits, I adapt to your needs. I’m reliable, detail-oriented, and focused on delivering work that actually helps your content perform better — not just look “edited.” If you have raw footage and a clear goal, I’ll take care of the editing so you can focus on creating. Send me your footage, references, and goal — I’ll handle the rest.
