Convoy is a full-stack SaaS application built for delivery companies, providing tools to manage couriers, assign delivery tasks, and optimize routing.

The backend is powered by Spring Boot with OAuth2 and Remember Me token authentication, PostgreSQL for persistence, and full-text search for fast lookups across orders and drivers.

The frontend uses React 19, React Router, and React Query.

Planned and in-progress features include revenue graphs filterable by time period, driver performance dashboards, driver ratings, and live order tracking for customers.

The project is actively in development.

Mudis is built on Netty with a custom client/server protocol leveraging NIO channels, boss/worker groups for separating connection acceptance from message handling.

It features an asynchronous pub/sub architecture with backpressure during high latency, implemented via Java’s Flow API SubmissionPublisher.

The project is multi-module and loosely coupled, with a shared module for domain objects — making it extensible and straightforward to build on.

Future goals include a caching layer with eviction strategies (LFU, LRU, MRU) and TTL support. Commands follow the Redis API convention: GET, SET, and more.

OpusDB is an academic deep-dive into relational database internals and concurrency mechanisms, implemented in Clojure. The goal is to build a minimal but fully functional database model using a practical mix of functional paradigms and object orientation — leveraging Clojure’s strong isolation semantics throughout.

The current implementation covers paging, a file manager, buffer pools, buffer management, and LRU/MRU eviction strategies backed by splay trees and dynamic state binding.

Transaction management is handled by a custom semi-eager STM implementation with eager conflict resolution, based on Tim Harris’s paper “Language Support for Lightweight Transactions.”

Future goals include indexing support, bitmap indexes, and further query execution primitives.

CarRevamp is a frontend website built for a local car detailing shop, serving as their social presence and advertising platform.

The site lists service pricing, provides easy navigation, and includes contact details — built with React, Tailwind CSS, and Motion for animations.

It also features a live chat integration for real-time customer support.

BeautyCode is the official website for a registered Georgian beauty products company, built to establish their social media presence and support marketing efforts.

Designed with a strong focus on UI/UX, the site is built with React, React Query, Motion for fluid animations, and Tailwind CSS. It includes live chat support for customer engagement.
