Senior Software Engineer | Backend Platforms | Python, AWS | Scalable Microservices & Real-Time Systems
I'm a Senior Software Engineer with over 20 years of experience building high-performance backend and data systems for real-time, transactional, and e-commerce platforms. I specialize in Python, Java, Node.js/NestJS, and AWS, with strong experience in LangChain, Scala, PostgreSQL, MongoDB, DynamoDB, and ArangoDB. My expertise spans full project lifecycles—from architecture design to production deployment—always with a focus on scalability, resilience, and clean engineering practices. I also work extensively with AI-assisted development tools, with nearly 2 years of hands-on experience building custom Claude Code skills and agents, and applying Spec-Driven Development (SDD) as a structured methodology to boost delivery speed and code quality in production environments. Key achievements: • Supported transactional backends in Scala for high-volume systems • Migrated legacy Java monoliths to Spring Boot microservices • Built serverless Python apps with AWS Lambda & LangChain agents • Designed ETL pipelines and real-time APIs for data platforms I thrive in remote, agile teams and combine technical depth with practical delivery.

Cultural Fit Analysis
The candidate has worked in various company sizes and types, from startups to established enterprises and consultancies, indicating adaptability to different organizational cultures. The experience spans multiple domains (e-commerce, finance, logistics, telecom), suggesting a broad interest and ability to contribute to diverse projects. The long tenure at Zaga Labs (10 years) and Emida Technologies (7 years) suggests loyalty and stability. However, the lack of explicit project details or team collaboration descriptions makes it difficult to fully assess cultural fit beyond technical adaptability.
Soft Skills & Operational Fit
The candidate's extensive experience across diverse projects and companies suggests adaptability and problem-solving skills. The descriptions of leading development lifecycles and improving operational efficiency indicate strong ownership and impact-driven work. The variety of roles and technologies implies a capacity for continuous learning and integration into different team environments. However, without direct assessment data, specific soft skills like teamwork, communication style, or stress handling cannot be definitively evaluated.
