About Me

A little about how I got here, and what I do when I'm not shipping code.

๐Ÿ“ Currently @ Appnox Technologies
๐Ÿงฉ Started coding out of pure curiosity
๐ŸŒ Loves traveling & exploring new places
๐Ÿ“š Always learning the newest AI tooling

It started with curiosity โ€” wanting to know how the things on a screen actually worked underneath. That pull toward "how does this work?" turned into learning to code, then into a Computer Science degree focused on AI & Machine Learning, and eventually into a career building real backend systems for real companies.

Today that curiosity shows up as a habit: every new LLM provider, every new deployment pattern, every interesting open-source tool โ€” I want to understand it well enough to use it in production, not just read about it. That's how a CRM ended up with a self-hosted model running on RunPod, and how a customer support assistant ended up speaking three channels through one RAG pipeline.

Outside of work, I'm usually reading about whatever's new in tech โ€” new models, new frameworks, new ways to deploy things faster โ€” or traveling when I get the chance, because a change of scenery is the best debugger for a tired brain.

AI-Powered CRM Platform

An enterprise CRM with AI email intelligence โ€” automated summarization and contextual next-email suggestions, powered by Claude and Groq.

The Challenge

Sales teams were losing deals to slow follow-ups โ€” manually summarizing email threads and figuring out what to send next ate hours each week.

My Role

Sole backend architect โ€” data models, API design, and the AI integration layer end-to-end.

Impact

Self-hosted Qwen 2.5 on RunPod cut per-request AI costs vs. pure API calls while Claude/Groq handled higher-stakes summarization.

The Challenge

Companies needed one AI assistant that stayed accurate to their own docs across three different channels, for both logged-in and anonymous users.

My Role

Designed the RAG pipeline โ€” document chunking, S3-based knowledge storage, and the retrieval logic feeding the LLM.

Impact

One knowledge base, three channels, consistent organization-aware answers instead of three separate bots.

The Challenge

Six different supplier APIs (Sabre, Distribusion, Trenitalia, Italo, CDS Groupe, RateHawk), each with its own data format, needed to feel like one system.

My Role

Built the supplier sync layer, unified data model, and queue-based background processing.

Impact

Deployed live with SSL/DNS management โ€” one consistent booking flow across all six suppliers.

Plant Disease Detection

Deep dive
The Challenge

Farmers often lack quick access to plant pathology expertise, leading to delayed treatment and crop loss.

My Role

Trained the TensorFlow model, built OpenCV preprocessing, and integrated it with a Java Android frontend + Python backend.

Impact

90%+ model accuracy on disease identification, giving farmers actionable insights in the field.
