Backend / Cloud
Go services, AWS/n8n automation, API integration, and cost-aware decisions shaped by FinOps thinking.
Maciej Karczmarz
I connect Go with 3D tools, focusing on performance and compute cost across both sides of the pipeline.
Profile
Performance across both sides of the pipeline.
I combine 3D graphics experience with learning backend and cloud. I look at systems through constraints, data flow, and compute cost.
3D / Technical Art
Blender models, mesh optimization, LODs, PBR, UE5, Unity, and procedural tools.
Skills / Stack
Go, cloud, automation, APIs, and 3D tools.
Go, Blender, UE5, Unity, Houdini, AWS, n8n, Gaea, Quixel, and Substance 3D Painter.

Selected Projects
Systems, automation, renderers, and simulations.
Projects shown through the problem, technical constraint, and practical value. This is not a technology tag cloud; it is a cross-section of how I think.
Project / 01
Gix
Real-time currency monitoring system that aggregates data from exchange points to provide current market insight.
- Role
- Backend / cloud cost engineering
- Constraint
- Live exchange-rate data, hosting, and operating cost must stay controlled.
- Impact
- Hosted on DigitalOcean and optimized for cost efficiency using FOCUS FinOps principles.
Project / 02
AI Agent / SmartOffer
Automation system for AB Bechcicki that transforms inquiries into Premium/Budget estimates using technical standards and parameters.
- Role
- Automation / RAG workflow engineering
- Constraint
- Requests need to become ready estimates quickly, consistently, and technically.
- Impact
- Connects RAG, n8n, and AWS into a repeatable sales and technical workflow.
Project / 03
GRAT
Interactive weather data visualization system integrating OpenWeatherMap, Google Maps, and Windy into one readable application.
- Role
- Application / API integration
- Constraint
- Environmental data from several sources has to become consistent and readable.
- Impact
- Shows API integration, data visualization, location context, and desktop-tool thinking.
Project / 04
GRATS
Minimal graphics renderer built to explore OpenGL and graphics programming fundamentals.
- Role
- Low-level graphics programming
- Constraint
- A renderer requires understanding the graphics pipeline closer to hardware and API behavior, not only finished engines.
- Impact
- Strengthens technical rendering knowledge that informs later asset, scene, and real-time performance decisions.
Project / 05
Sand Sim
Granular physics simulation focused on natural particle behavior and environmental interactions.
- Role
- Simulation / performance thinking
- Constraint
- A high number of particles needs simple, stable rules and efficient behavior updates.
- Impact
- Shows simulation thinking, compute efficiency, and believable behavior under motion.
