  • RoleChief AI Engineer
  • StatusOpen to Work

I'm Zubayer — an AI & Machine Learning Engineer with 4+ years of hands-on experience building production-grade intelligent systems. My work spans natural language processing, computer vision, and generative AI, deployed across healthcare, media, and business automation sectors.

Currently serving as Chief AI Engineer at EVU Inc., a venture-backed startup ecosystem with 250+ members, where I architect advanced NLP models, RAG pipelines, and MLOps infrastructure. Previously, I've delivered AI solutions for USAID's Breakthrough ACTION program and international media organizations.

Beyond engineering, I'm a lifelong learner and open-source contributor. I believe AI should be accessible, multilingual, and purposeful — which is why my work consistently bridges technical innovation with real human impact.

Rolac World Cup Photobooth — AI Football Jersey Generator

Rolac World Cup Photobooth — AI Football Jersey Generator

Engineered a complete end-to-end system, not just a model demo. A React 18 + Vite SPA handles camera capture, team selection (10 countries) and result download; a Flask API served by waitress (64 threads) behind nginx generates the composite. Google Gemini fuses the selfie and a jersey reference in one pass, backed by a self-hosted CV pipeline (InsightFace buffalo_l + inswapper, ONNX Runtime, MediaPipe segmentation, GFPGAN/OpenCV) with affine alignment, LAB colour matching and seamless blending for direct face/head-swap modes. An admin panel reviews every generated record.

Face Swiper — Production-Grade AI Face & Head Swap
03AI/ML · Computer Vision

Face Swiper — Production-Grade AI Face & Head Swap

Built a two-mode pipeline. FACE mode swaps the face while preserving the subject's hairline and surrounding context; HEAD mode performs a full-head transfer. The system uses InsightFace (buffalo_l detector + inswapper) on ONNX Runtime for the core swap, MediaPipe segmentation to isolate regions, affine alignment for geometry, LAB colour matching for tone, and seamless blending to remove seams. GFPGAN restores and upscales facial detail in the final output. Supports group photos and a UI face picker.

V-TRYON AI — Virtual Clothing Try-On Studio

V-TRYON AI — Virtual Clothing Try-On Studio

Built a two-stage AI pipeline. Stage 1 uses SegFormer B2 Clothes to segment upper-body clothing regions (shirt, top, jacket, dress) from the person photo and produce a dilated binary mask. Stage 2 feeds that mask to Stable Diffusion Inpainting with a carefully crafted fashion-photography prompt to generate the new garment realistically onto the body. The person image is resized to 512×768 (Stable Diffusion's sweet spot) and the result is returned as a base64 PNG. A modern dark glassmorphism UI offers drag-and-drop uploads, real-time API health status, progress indicators and one-click downloads.

PinVault — Secure Internal Vendor Map Platform

PinVault — Secure Internal Vendor Map Platform

Built a full-stack platform with a Node.js + Express + MySQL backend and a fast single-file HTML/Leaflet frontend. Role-based access (super admin vs employee) is enforced with JWT + bcrypt. Vendors can be created from a location search or a direct map click, with fields for description, notes, phone, website, category and coordinates. Super admins manage staff, edit/remove vendors, and import/export data in CSV and JSON, plus export the map as an image. Browser-side privacy deterrents include username/timestamp watermarking, right-click and copy blocking, dev-tools deterrence, and Print-Screen detection with a capture-shield overlay.
