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.https://provokedynamic.tech/portfolio/mudis/Tue, 03 Feb 2026 00:00:00 +0000https://provokedynamic.tech/portfolio/mudis/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.https://provokedynamic.tech/posts/datasource-proxy/Wed, 14 Jan 2026 00:00:00 +0000https://provokedynamic.tech/posts/datasource-proxy/Why Use a DataSource Proxy? The Hibernate user guide recommends using a DataSource proxy instead of default logging frameworks like Log4j or Logback. While traditional logging frameworks can show you SQL statements, a DataSource proxy gives you much more insight into what’s happening at the JDBC level. Benefits of using a DataSource proxy: Statement execution time - See how long each query takes, making performance issues easier to spot JDBC batching logs - Verify that batch operations are actually being batched, not executed one by one Database connection monitoring - Track connection acquisition and release patterns N+1 query detection - Assert the expected number of queries in tests, catching performance problems early Traditional logging frameworks like Logback can be configured via spring-logback.https://provokedynamic.tech/posts/nginx/Mon, 05 Jan 2026 00:00:00 +0000https://provokedynamic.tech/posts/nginx/Nginx is a fast, efficient web server that handles lots of concurrent connections without eating your RAM. It’s used for serving sites, routing traffic, and load balancing. Root vs Alias root - Adds the request path to your root directory: location /admin/ { root /var/www/locked; } Request for /admin/secret.html looks at /var/www/locked/admin/secret.html. Notice it kept the /admin/ part. alias - Replaces the matched location: location /admin/ { alias /var/www/locked/; } Same request now looks at /var/www/locked/secret.https://provokedynamic.tech/about/Sun, 21 Dec 2025 00:00:00 +0000https://provokedynamic.tech/about/Hello, you’ve reached the blog of mine. I’m currently pursuing a Computer Science degree at Kutaisi International University; I don’t believe in utter idealism, and I’m always trying (at least) to understand how things work under the hood; I spend a lot of time reading books about software, still, they seem like the best way to learn things;https://provokedynamic.tech/portfolio/opusdb/Thu, 04 Dec 2025 00:00:00 +0000https://provokedynamic.tech/portfolio/opusdb/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.https://provokedynamic.tech/portfolio/car-revamp/Mon, 20 Oct 2025 00:00:00 +0000https://provokedynamic.tech/portfolio/car-revamp/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.https://provokedynamic.tech/portfolio/beauty-code/Sun, 18 May 2025 00:00:00 +0000https://provokedynamic.tech/portfolio/beauty-code/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.
