Hi, I'm Andrej Kincel

Staff+ Engineering Lead of Global eCommerce Teams

Tech and people lead of globally distributed engineering teams in the eCommerce domain, building highly available, fault-tolerant systems that process millions of transactions with exceptional throughput. Expert in RESTful microservices with TypeScript/Node.js and C#/.NET core, AWS cloud services, and serverless architecture.

Where I've Worked

Principal Software Engineer @ Cimpress
July 2023 - Present

Engineering Lead for global platform teams building and scaling eCommerce Website and Wholesale Pricing systems. I own technical direction, architecture, and engineering quality across distributed teams working in a modern, API-first, serverless environment on AWS.

  • Leading architectural design and modernization efforts, with an emphasis on event-driven, scalable, and maintainable systems aligned across multiple product teams
  • Collaborating closely with Product, UX, and Engineering Management to turn complex business needs into robust, performant technical solutions
  • Driving engineering best practices, including code quality, CI/CD workflows, performance tuning, and AWS cost optimization
  • Mentoring engineers and supporting their growth through technical coaching, feedback, and structured promotion processes
  • Guiding system evolution through thoughtful adoption of new technologies and proactive handling of non-functional requirements like scalability, reliability, and availability
Lead Software Engineer @ Cimpress
August 2017 - July 2023

I led cross-functional software engineering teams in the fulfillment, pricing, and invoicing areas.

  • Acted as a people manager, coached team members, led performance reviews, 360 feedback sessions, hiring, technical and behavioral interviews
  • Collaborated with product managers, UX researchers, and team leads in fully-remote settings across time-zones
  • Prepared and held technical demos, presentations to customers, and knowledge sharing sessions
  • Designed and implemented microservices utilizing serverless architecture (AWS Lambda, Fargate) and asynchronous event-processing (AWS SNS, SQS, Step Functions)
  • Optimized the response time, availability, and security of RESTful HTTP APIs (AWS CloudFront, ApiGateway, WAF)
  • Used SQL (PostgreSQL) and NoSQL (DynamoDB, ElasticSearch) databases and built transformation pipelines for data products (DBT, Snowflake)
  • Built frontend web applications using Vue.js and React.js
  • Managed deployment stories (GitLab, GitHub actions) and wrote Infrastructure as Code (CloudFormation)
Software Engineer @ Zalando Payments SE & Co. KG
November 2015 - July 2017

I worked on a payment processing product (credit card, invoice, cash on delivery). I was focused on the steering part deciding when a payment should be executed, keeping simple accounting, calculating payment balances, and performing reconciliation with payment gateways.

  • Built scalable microservices in Java and Spring boot deployed to AWS ECS backed by EC2
  • Run and monitored self-managed Cassandra cluster
