Solution Architect · Full-Stack Technical Lead
Cracow, Poland
Solution Architect and hands-on technical lead. I take fragmented, legacy systems and turn them into consolidated cloud architectures - then stay in the code to deliver them.
This assistant only answers questions about Maciej Ziolko's professional background, grounded in his real CV - nothing else.
Led the end-to-end re-architecture of a complex multi-provider system onto consolidated AWS services, removing fragmented third-party infrastructure while the existing platform stayed live.
Designed and shipped an AWS Bedrock (Claude) content-moderation pipeline integrated into the backend domain layer, with automated classification, fallback logic and audit tracking.
Introduced a production Redis caching layer for API queries and EFS-based image caching across Kubernetes pods, reducing latency and enabling horizontal scalability.
Partnered with the Product Owner and VP of Engineering to set technical direction and delivery strategy, and grew the engineering team around it.
I lead architecture end to end: gathering requirements with product and executive stakeholders, defining the technical roadmap, and staying hands-on through implementation. At DoSomething I directed the full transformation of a fragmented multi-provider stack into a unified AWS platform - replacing third-party infrastructure, redesigning the data model around Domain-Driven Design, and introducing caching and event-driven messaging to cut latency and operating cost, all while keeping the legacy system stable in production.
I design with Domain-Driven Design, CQRS, microservices and event-driven patterns across a broad AWS surface, and I am AWS and Google Cloud certified in Generative AI. I have shipped production GenAI systems, including an AWS Bedrock content-moderation pipeline embedded in the backend domain layer with fallback logic and audit tracking.
I lead people as well as architecture - growing and mentoring the engineering team at DoSomething, and partnering directly with Product Owners and VP-level stakeholders to align technical direction with business outcomes.
