About Demaceo Vincent

Shipped: Five production apps in twelve months, solo — civic tech, privacy AI, PropTech, spatial AI, and real-time voice.
Built: Firebase tokens verified straight against Google's JWKS — no Admin SDK, no service account sitting on a server to leak.
Owned: Architecture, security, compliance docs, 3D graphics. Nothing handed off because it wasn't my job.
On Record: A PBS documentary on public interest tech, and a panel at SXSW EDU 2025.

Strengths

Solo Full-Stack Shipper. Sole engineer, designer, and product owner across 5 production apps — civic tech, privacy AI, PropTech, spatial AI, and real-time translation — shipped within a single 12-month stretch.
Security-First Architect. Verified Firebase tokens directly against Google's JWKS endpoint instead of the Admin SDK, and built an on-device AES-256-GCM vault so raw personal data never leaves the phone.
AI Systems Integrator. Shipped real-time Gemini streaming, an ElevenLabs voice pipeline, and dual-key failover with rate limiting — production AI, not a demo wrapper.
Compliance-Minded Builder. Wrote the privacy policy, security policy, terms of service, and data-deletion docs myself — GDPR/CCPA readiness shipped alongside the feature, not after a legal review.
Mentor & Educator. Taught full-stack JavaScript as a bootcamp TA and ran 1:1 mentoring, mock interviews, and code reviews for Turing School alumni for over three years.
Public Interest Technologist. Featured in a Roadtrip Nation documentary on public interest tech and served as an SXSW EDU 2025 panelist on youth, technology, and media. Watch the documentary
Production-Grade Craftsman. Strict TypeScript, CI-gated pipelines (lint → typecheck → test → secret scan), and pre-commit hooks by default — across every shipped project, not just the polished ones.

UX is the sum of all things. There’s no style over substance here. I bring together form and function to create something that looks good and performs brilliantly. Simple.
Accessible to All. Design should be made for everyone, hence why I strive for inclusivity. Every user, regardless of ability, deserves a seamless, enjoyable experience.
Creator. Partner. Collaborator. Ideas are far from linear. As designer and developer, I can spearhead, support or polish your project or product at any stage it needs it.
Clean - In thinking & in style. Minimal and effective. This is my mantra and method. Clean code, fuss-free interfaces and expert execution, design as it should be.
Transparency in Collaboration. I believe in writing clean, well-documented code and fostering open communication. Whether in code reviews or team discussions, clarity is key.
Performance Matters. A great user experience extends beyond design. Optimized code, fast load times, and smooth interactions make all the difference.
Automation Over Repetition. If a task can be automated, it should be. From CI/CD pipelines to utility scripts, I minimize redundant work and maximize efficiency.
Tech for Good. Whether it’s environmental sustainability, accessibility, or community-driven innovation, I build with impact in mind.
