I build and modernize mission-critical systems for finance, government, and healthcare organizations. I have delivered measurable performance improvements, including reducing response times by up to 94% and transforming manual data retrieval processes that took hours or weeks into workflows completed in 1–6 seconds. My back-end experience includes PHP, Laravel, Node.js, Express, Java, REST APIs, SQL, Redis, and legacy Zend Framework systems. I also build modern front-end interfaces with React, JavaScript, and TypeScript. I am experienced in production delivery, code review, deployment risk validation, CI/CD, Docker-based environments, and technical coordination with internal teams and external vendors. My staged delivery practices have been associated with significantly fewer production rollbacks. I have led full-stack modernization initiatives, API migrations, database optimization, caching implementations, real-time WebSocket features, and internal enterprise platforms. I have also served as an interim Tech Lead and Engineering Manager. I am especially interested in applying Generative AI, RAG, LangChain, and LLMs to practical business problems, including natural-language data access and corporate knowledge systems. ## Skills 30 capabilities[API Development](https://jobicy.com/talent/api-development.md)[Caching](https://jobicy.com/talent/caching.md)[CI CD](https://jobicy.com/talent/ci-cd.md)[Code Review](https://jobicy.com/talent/code-review.md)[Data Analysis](https://jobicy.com/talent/data-analysis.md)[Database Optimization](https://jobicy.com/talent/database-optimization.md)[Generative AI](https://jobicy.com/talent/generative-ai.md)[Java](https://jobicy.com/talent/java.md)[JavaScript](https://jobicy.com/talent/javascript.md)[Kanban](https://jobicy.com/talent/kanban.md)[Laravel](https://jobicy.com/talent/laravel.md)[Large Language Models](https://jobicy.com/talent/large-language-models.md)[Legacy System Modernization](https://jobicy.com/talent/legacy-system-modernization.md)[Microservices](https://jobicy.com/talent/microservices.md)[Performance Optimization](https://jobicy.com/talent/performance-optimization.md)[PHP](https://jobicy.com/talent/php.md)[Python](https://jobicy.com/talent/python.md)[RAG](https://jobicy.com/talent/rag.md)[React](https://jobicy.com/talent/react.md)[Redis](https://jobicy.com/talent/redis.md)[REST APIs](https://jobicy.com/talent/rest-apis.md)[Risk Management](https://jobicy.com/talent/risk-management.md)[Scrum](https://jobicy.com/talent/scrum.md)[Software Engineering](https://jobicy.com/talent/software-engineering.md)[SQL](https://jobicy.com/talent/sql.md)[System Modernization](https://jobicy.com/talent/system-modernization.md)[Team Leadership](https://jobicy.com/talent/team-leadership.md)[Technical Leadership](https://jobicy.com/talent/technical-leadership.md)[TypeScript](https://jobicy.com/talent/typescript.md)[UX Design](https://jobicy.com/talent/ux-design.md) ##
