Adam Horvath

Engineered and maintained AI-enabled systems for e-commerce operations using Apache Kafka, PostgreSQL, Go, and Docker, improving how customer-service data supports analytics and AI use cases. Built and maintained tooling integrations with Jenkins, Git, and Docker to standardize integration/deployment across multiple services and cloud environments. Partnered with product managers to align technical requirements with business goals, delivering CRM/AI data analysis that met stakeholder expectations. Performed code reviews and architectural refactoring to remove performance hotspots and simplify service operations under load. Designed AI-enabled system architecture with Kubernetes, Terraform, Kafka, and PostgreSQL to enhance data integration, failover, and workflow resilience. Authored documentation and service/deployment behavior guides using Swagger to reduce reliance on tribal knowledge.

Engineered and maintained API gateway-related microservices on Go, Node.js, Docker, and Kubernetes, supporting e-commerce operation data handling and smoother day-to-day workflow. Authored and maintained API specifications in OpenAPI, keeping documentation synchronized with live contracts to enable consistent cross-team integrations. Refactored performance-critical paths across Go/Node.js/PostgreSQL to keep resource usage efficient during high request load. Developed automated testing frameworks for API and service functionality using Jest, Mocha, and Jenkins. Established API versioning and OAuth2-based authentication protocols, improving integration consistency for consumers. Resolved production issues by tracing requests through microservices and using Grafana/Prometheus/Splunk for operational visibility.

Developed and maintained applications using Java, Spring Boot, Hibernate, and PostgreSQL for e-commerce-related systems, strengthening data access and service logic. Translated business data requirements into Jira tickets and collaborated with product managers and engineers on actionable increments for tooling integrations. Created comprehensive unit tests with JUnit and Mockito to enable effective verification and safer incremental releases. Debugged customer-service database issues using Splunk, New Relic, and SQL in collaboration with senior engineers to isolate root causes and improve system reliability. Conducted structured code reviews and supported quality-focused delivery using Git.
