Peter Puskas

Senior Software Engineer with over 20 years of experience in agile software development, with a strong focus on backend systems and cloud-native architecture. A hands-on engineer with proven expertise in designing and implementing scalable solutions using Python, with a strong foundational background in Java and Shell scripting. Specialist in cloud environments — primarily AWS — leveraging cloud-native services to deliver secure, high-performance applications.

Looking to continue growing as a hands-on senior engineer, deepening expertise in cloud-native and serverless architecture while taking on complex backend challenges. Particularly interested in roles that value technical ownership over people management, with a growing focus on applying AWS and backend experience to AI agent systems — tool orchestration, state management, and observability for LLM-based workflows.

Senior Software Engineer at Vestas (2024-01 – 2026-03)

Engineered and implemented cloud-native backend solutions within the AWS ecosystem, improving development velocity and operational efficiency while delivering measurable cost optimization.

• Built real-time data streaming pipelines with Apache Flink to process high-volume live telemetry from distributed energy resources, enabling high-performance analytics for mission-critical wind turbine operations.
• Built Databricks pipelines to process wind turbine telemetry, feeding calculated metrics into a custom Delta table and TimescaleDB that powered multiple downstream monitoring and analytics tools.
• Implemented an event-driven architecture enabling dynamic business report generation, supporting expanded market penetration and competitive product differentiation.
• Contributed to the technical integration of Utopus Insights' analytics engines into the global Vestas environment, ensuring compliance with enterprise-level security standards and high system uptime.
• Delivered Python microservices work as a hands-on technical contributor, designing optimized data-processing pipelines and core backend systems for complex business logic.

Senior Software Developer at Utopus Insights (2018-05 – 2024-01)

Owned the development of the core backend application, initially built with the Java Spring Framework. Following the company's acquisition by Vestas, led the cloud-migration effort — fully re-engineering the solution using AWS-native services with a Python-based implementation, ensuring development continuity, scalability, and operational resilience.

• Designed and optimized high-throughput RESTful services using AWS API Gateway, implementing request transformation, rate limiting, and robust security protocols (CORS, custom authorizers).
• Built cost-effective, scalable web backends and data pipelines (AWS Lambda, ElastiCache, TimescaleDB, Apache Flink) to process high-volume, live wind turbine telemetry and renewable energy analytics.
• Authored production-grade business logic following Clean Code principles and Test-Driven Development (TDD), ensuring reliability and long-term maintainability.

Senior Software Developer, IBM Research & Development Germany at IBM (2011-11 – 2017-12)

Key projects in agile product development, primarily using Java, Shell scripting, and SQL:

• Designed and developed the backend and REST API for the IBM Spectrum Scale GUI, improving administrability of a distributed cluster file system (formerly GPFS) used across enterprise storage environments.
• Contributed to the Storwize V7000 Unified Product — high-performance network-attached storage with Scale Out File Services, Cluster, and GPFS.
• Contributed to Scale Out Network Attached Storage (SONAS).

Senior Software Developer, IBM Research & Development Germany at Gamax Kft. (IBM Germany Contractor) (2002-01 – 2011-10)

Key projects in agile product development, primarily using Java, Shell scripting, and SQL:

• Contributed to the Storwize V7000 Unified Product, Scale Out Network Attached Storage (SONAS), and IBM Director.
• Developed embedded telemetry and fleet management systems (Hochtanus Universal Embedded Telematics Framework), enabling remote device monitoring and management at scale.
• Built manufacturing automation and shop floor control systems (MOF, ACS), improving production tracking and operational visibility.
• Delivered the OTCS Operation Training and Certification System.
