• Today – BrainRoad Labs Website

Summer '25

Built the BrainRoad Labs website from scratch, designing a custom scroll engine with inertia analysis to ensure smooth, intuitive navigation — especially on Apple devices (less optimal with traditional mouse scrolling) — and delivering a fully responsive, high-performance UI/UX.

• Founder & Full-Stack Dev – Betsy

May 2025 - In Progress...

Currently building BETSY, an AI-powered virtual language teacher that speaks in real time using GPT-4o and LiveKit — designed to feel like a real instructor, with upcoming support for written content and interactive exercises.

• Full-Stack Dev – CheckAI

April 2025

Engineered CheckAI, a proof-of-concept change detection tool using the “The Change You Want to See” co-attention model (WACV 2023) to automate before/after image comparison for short-term rentals. I integrated the full inference pipeline via Flask and served a responsive UI with bounding-box overlays.
To meet hardware constraints, I adapted the training and inference flow to run entirely on CPU — including Apple Silicon — by bypassing CUDA dependencies, optimizing model loading, and tweaking detection thresholds and visualizations.
The result: on-demand visual diffing with pixel-accurate masks and seamless UX on low-cost infrastructure.

• Founder & Full-Stack Dev – IK-Generator v2

February-March 2025

Rebuilt IK-Generator (v2) App, nine years after developing its first version. Migrated a monolithic Symfony app with MySQL, Elasticsearch, and OSRM — previously installed bare-metal — into a fully containerized architecture using Docker and Docker Compose.
Implemented secure server automation (Debian hardening, SSH lockdown, firewall, fail2ban...), streamlined data pipelines for database imports and ES population, and created scripted deployment flows for both dev and prod environments on Scaleway.

• Lead Dev – DoYouSpeakGaultier? [JPG's GenAI experience]

June-September 2024 (4-month build)

Summary.

Built the end-to-end GenAI experience for JPG's ecommerce site: users pick a Parisian phrase (available in 7 languages), record a short mouth clip, and the system isolates, beautifies, and composites the lips onto AI-generated skies, publishing brand-safe videos to a live “wall of mouths”.
At each key step, Xano orchestrated the flow and sent transactional emails via SendGrid to keep users informed.

Role & scope

• Lead engineer (me): front-end JavaScript, back-end, GenAI/ML pipeline (ComfyUI), DevOps, and moderation tooling.
• Team: UX/UI designer + one front collaborator; I owned the pipeline, infra, and all of the app logic.

Stack

• GenAI / ML: ComfyUI with custom SDXL model, custom LoRA(s) for lipstick styling (trained on synthetic dataset, released on CivitAI), AnimateDiff for frame-to-frame consistency, SAM + Grounding DINO for segmentation/detection, ControlNet, CLIP (pos/neg), KSampler, FILM VFI for interpolation, VAE, video combine...
• Infra: AWS EC2 (ComfyUI in Docker), S3 for input/output storage.
• Backend: Xano (job orchestration, APIs, DB in Postgres, callback handling, SendGrid integration).
• Front: vanilla JavaScript experience embedded in JPG's site; mobile & desktop camera capture.
• Content: backgrounds via Midjourney, JPG's voiceover via ElevenLabs.
• Admin: custom Vue.js back-office for moderation and wall management.

ComfyUI Workflow

1. Fetch video from S3 → drop 1 frame out of 2 to reduce RAM, since one user video produced 3 outputs (HD+FHD landscape for the site, and FHD portrait for social).
2. Generate new video via KSampler with prompts (pos/neg), ControlNets, the source video, and AnimateDiff to enforce temporal consistency.
3. Mask/detour the new video.
4. In parallel, generate a second “lipstick-only” red-lips video, used as a guiding mask to help SAM + Grounding DINO perform more accurate segmentation.
5. Apply this mask to the main custom video.
6. Upscale useful frames from 1024x576 to HD and FHD variants.
7. Composite lips onto AI skies.
8. FILM VFI interpolation → 60 fps for smoothness.
9. Mix original audio back into the final render.
10. Push 3 new videos (HD, FHD, social) to S3 + Postgres/Xano, triggering callbacks and user notifications via SendGrid.

Engineering highlights

• Designed a multi-branch ComfyUI pipeline combining AnimateDiff, ControlNets, segmentation feedback loops (red-lips masking) and more.
• Balanced RAM + GPU limits by frame-sampling + smart upscale, while still hitting high-res deliverables (example below).
• Automated 7-language UX with transactional emails for transparency (recorded → processing → published).
• Built a moderation back-office (Vue.js) with review queues, “On the Wall” toggles, and safe-publish controls.
• Containerized inference on EC2 for reproducibility and scale.

Result

A visually striking, multilingual UGC experience that transforms noisy webcam clips into branded AI videos, manages moderation, and delights users with live publication on the “wall of mouths”.

Live Generation Example

• CEO / CTO / Product Owner – Shaaare App

September '23 – April '25

• Pivot from Ko Social Network to focus on AI-powered content monetization.
• Developed Shaaare, a social network where photo & video posts were automatically evaluated by GPT-4o, rewarding creators in XKO tokens (25–100 XKO per post) directly on blockchain.
• Implemented anti-spam measures (3–5 posts/day limit, verified users) and automatic rejection of low-quality content (score ≤ 25).
• Built and released three full versions, published on Google Play Store, blocked on Apple App Store due to in-app crypto monetization rules.
• Achieved JEI (Jeune Entreprise Innovante) status in France.
• Raised nearly €1M from 100+ investors across both Ko & Shaaare projects.

• CEO / CTO / Product Owner – Ko Social Network [Featured at CES '23]

April '20 – September '23

Built and led a Web3 social network with a team of front-end and back-end developers, UI/UX designers, and a marketing squad. The project aimed to give content ownership back to users through NFT-based posts and a native cryptocurrency (XKO).
• Decentralized Ownership: Users could mint photo and video NFTs directly from their devices and manage them via a non-custodial in-app wallet.
• Seamless UX + Security: Implemented ERC-20 meta-transactions on Polygon and Ethereum, enabling gasless transactions with transparent signature handling.
• Native Token Economy: Designed Like+Ko (tip-based likes with customizable XKO amounts) and Pay-to-View content monetization.
• Crypto Features: Enabled peer-to-peer XKO transfers and NFT minting with frictionless mobile experience.
• Recognition: Invited to CES 2023 with a "Spotlight Tech for Good" mention, leading to high-level discussions with Jamie Holcombe (USPTO CIO).
• Social App Experience: Positioned as a blend of TikTok + Instagram, with support for text, audio, photo, and video posts — NFTs reserved for photo/video content.
Despite full feature completion and completion of many versions, Apple Store in-app monetization restrictions and fundraising challenges in France led to the project pivoting into Shaaare.
