Excel Espina is a technology leader and software engineer with 8 years of experience building AI-driven products, mobile apps, and resilient infrastructure across startups, education, and nonprofit sectors. As Director of IT at a large NYC church he scaled livestreaming and web systems to support 200% traffic growth while cutting costs 25% and improving load times 50%, and as CTO/co‑founder he designed LLM-based analysis pipelines that drove early user traction and monetization. He combines hands-on machine learning and computer vision expertise from his Computer Science studies with pragmatic product delivery—shipping iOS/Android apps, Django/React services, and automated deployment pipelines. Known for turning user feedback into actionable roadmaps, he also has a track record of improving operational support (95% ticket resolution within 24 hours) and securing platforms to reduce misuse by 40%. Based in New York, he is open to freelance and innovative roles where he can fuse research-driven ML techniques with production-grade systems. An uncommon thread in his background is experience spanning both grassroots community tech (church A/V and member apps) and early-stage startup product-market testing.
