Volodymyr K.

I'm Volodymyr, a full-stack developer with 13+ years of experience building scalable web applications, eCommerce platforms, mobile apps, and security-focused systems. I work with startups and established businesses that need a developer who understands both the technical side and the business goals behind every project. Beyond client work, I'm the sole developer behind SecureBit.chat - an open-source cross-platform P2P encrypted messenger with a shared cryptographic core written in Rust. Web, desktop (Windows/macOS/Linux), and mobile - designed, built, and maintained by one person. Zero servers, zero metadata, end-to-end encrypted. It's how I stay sharp on security architecture, cryptographic protocols, and shipping real products that work in production. --- What I Build WordPress & WooCommerce Custom themes, plugins, and deep API integrations. High-performance stores built to scale - not bloated page builders stacked on templates. Laravel Scalable backend systems, RESTful APIs, admin dashboards, and complex business logic. Clean architecture built for long-term maintainability. Flutter & Mobile Development Cross-platform Android and iOS apps built with Flutter and Dart. From startup MVPs to full production releases - one codebase, native performance. Web3 & Blockchain Smart contract development, blockchain integrations, NFT platforms, and decentralized application architecture. Solidity, Ethereum, and Web3 tooling. Full Stack Web Development End-to-end builds using PHP, Python, JavaScript, React, Node.js, Django, MySQL, Firebase, and Supabase. Frontend, backend, deployment - full pipeline covered. --- My Approach Before writing a single line of code, I take time to understand your business, your users, and your actual goals. I ask the right questions, flag potential issues early, and give honest input even when it's not what you expected to hear. That approach saves clients time, money, and the painful experience of rebuilding something that wasn't planned properly from the start. --- Tech Stack Frontend: HTML5 · CSS3 · JavaScript · jQuery · React · Tailwind CSS Backend: PHP · Laravel · Python · Django · Node.js Mobile: Flutter · Dart · Cordova CMS: WordPress · WooCommerce · Drupal Web3: Solidity · Ethereum · Smart Contracts · NFT Databases: MySQL · PostgreSQL · Firebase · Supabase Tools: REST API · GraphQL · Git · Docker · AWS · Figma --- Who I Work With Startups building their first product · Businesses scaling existing platforms · Agencies needing a reliable senior developer · Entrepreneurs turning ideas into launched products --- Looking for a developer who communicates clearly, delivers consistently, and treats your project like it matters?
