AI Engineer | Agents, Automation & Integrations

Cover image for I'm currently building Omnicrm.chat (http://OmniCRM.chat).

I'm currently building Omnicrm.chat (http://OmniCRM.chat). A CRM and multichannel communication platform designed to keep customer conversations, sales opportunities, and operational workflows in a single workspace. Most teams still manage WhatsApp, Telegram, email, proposals, tasks, and customer records across multiple disconnected tools. The result is lost context, duplicated work, and a fragmented customer experience. With OmniCRM.chat (http://OmniCRM.chat), conversations can evolve into opportunities, projects, and tasks without manual data entry. The goal is to connect communication, CRM, and execution into one platform, while creating a foundation for future AI-driven automation across the entire customer lifecycle.

Cover image for AI-Powered OCR Pipeline for Document Processing

Most OCR systems stop at text extraction. The real value starts after the document is read. In this project, I built an AI-powered OCR pipeline capable of extracting text from invoices, contracts, reports, and forms while also classifying the document type and identifying key information automatically. Instead of returning raw text only, the system structures the data into usable outputs for automation workflows, CRMs, ERPs, and AI agents. This reduces manual processing time and makes documents immediately actionable inside business operations. The stack combines OCR engines with LLM-based processing for contextual understanding, keyword extraction, and intelligent classification. The result is a more reliable document processing flow that can integrate directly with APIs, databases, and automation systems. This is where AI engineering becomes practical: transforming unstructured files into structured business data at scale

Cover image for Intelligent AI Agent for Business Automation

Most businesses are already experimenting with AI — but very few are using it the right way. A generic chatbot is not enough. What actually drives value is a custom AI agent built around your workflows, capable of calling APIs, automating decisions, and integrating directly with your systems. This is where AI stops being a demo and starts becoming infrastructure. With the right architecture, your AI can handle operations, reduce manual work, and scale processes without increasing costs — from customer support to internal tools, data processing, and beyond. If you're thinking about building a real AI solution tailored to your business, let’s talk.

Cover image for What if an ancient Egyptian

What if an ancient Egyptian relic was actually the hero of a lost retro console game? For the FLORA Museum Challenge, I reimagined the "Faience amulet in the form of a tree frog" (Ptolemaic Period, 330–30 BCE) from The Metropolitan Museum of Art’s Open Access archive into a playable, low-poly 32-bit platformer hero. 🏛️ Original Met piece: metmuseum.org/art/collection/search/243774

Cover image for WHAT WE WEAR TO PROTECT
What

WHAT WE WEAR TO PROTECT What if historical armor left the museum and walked into a 1990s fashion editorial? For the #FLORAMuseum challenge, I used four original armor pieces from The Met as my creative brief — without changing the pieces themselves. I only changed the context: real models, fashion photography, a magazine cover and a VHS-style behind-the-scenes. 5,000 years of protection. One new context. Original references from The Met: https://www.metmuseum.org/art/collection/search/24008 https://www.metmuseum.org/art/collection/search/25640 https://www.metmuseum.org/art/collection/search/23205 https://www.metmuseum.org/art/collection/search/24671 Built with @floraai #FLORAMuseum

Cover image for What if a "still life"

What if a "still life" wasn't dead at all? 🍎🌱 For the #FLORAMuseum challenge, I reimagined an open-access work from @metmuseum without changing its composition, lighting, or adding anything to the scene. I simply let time move forward. The fruit decays, seeds begin to sprout, and a “dead” still life slowly becomes a living cycle again. Built and iterated in FLORA, using the original artwork as the visual anchor. Nature is never truly still. And never truly dead. 🌱
