Profile

I am an Applied Mathematics student focused on machine learning, explainable AI, statistical modeling, real-time systems, and full-stack software engineering.

My work connects mathematical structure with practical implementation: ML experiments, production-minded web systems, backend workflows, and real-time platforms built for actual users and organizations.


Current Work

Okhten Group LLC

Founder / Full-Stack Developer
okhtengroup.com

I founded Okhten Group LLC, a Florida-based web studio where I build business-facing web systems for small local businesses.

The technical focus is on mobile-friendly websites, local SEO infrastructure, contact and booking workflows, lead-capture flows, structured metadata, deployment, and lightweight digital systems that help businesses present themselves more professionally online.


EECAA Platform

Founder & President / Full-Stack Engineer
eecaa-website.vercel.app

I founded and currently lead EECAA, a university student organization with 50+ active members.

I also engineered the platform behind it, including content workflows, event and media management, role-based access control, admin dashboards, and backend logic for organization operations.


Technical Direction

Machine Learning & Explainable AI
Model evaluation, feature engineering, CNN interpretability, saliency methods, Grad-CAM, Integrated Gradients, and counterfactual explanations.

Full-Stack Systems
Next.js applications, backend workflows, REST APIs, Supabase, PostgreSQL, authentication, admin dashboards, and user-facing web platforms.

Real-Time Engineering
WebSockets, Supabase Realtime, session synchronization, multiplayer state handling, and low-latency interaction design.

Applied Mathematics
Linear algebra, probability, statistics, optimization, numerical methods, and structured problem solving.

Philosophy

A system is not complete unless it can be understood, debugged, extended, and trusted under pressure.

I care about clear structure, predictable behavior, and engineering decisions that survive real use.
