Turning business vision into systems that scale.
I'm Dzmitry Harupa, Head of Architecture. 17 years of high-load systems, 10 of them in iGaming. I design architecture, take AI/ML to production and still write code myself. TOGAF, SAFe and AWS certified. 100% remote.

Outcomes you can measure.
AI call-center automation
>$1.2M saved per year on AWS Bedrock & SageMaker.
NATS event mesh at scale
200K+ msgs/sec across 1000+ systems, <100ms p99 latency.
Monolith → microservices
40% of transactional load migrated; release lead time down 57%, deploys under 15 minutes.
Decisions on data. Results in numbers.
An architect who stays until it ships.
Ten years in iGaming: Casino, Sports, Poker, PAM, payments and CRM. Production AI/ML on AWS Bedrock, SageMaker and LangGraph.
I grew an architecture practice from 6 to 12 architects plus 20 system analysts, mentored three of them to Head-of-Technology roles and led 200+ engineers. I still write production code.
Notes on architecture and AI.
What I work with: architecture, AI/ML, iGaming.
From canvas to studio: a reusable library, parallel runs and auto-packaged clips
Earlier the canvas assembled a single clip. Now it has a name — Vini Studio — and it grew from a graph into a workspace where I can turn out clips in batches. Inside: why the element library and the render cache are one mechanism over an artifacts table; a prompt manager with system and personal templates; a node that compresses the previous episode into ~1000 tokens of memory; parallel runs and the topological-sort bug that made scenes start before the scriptwriter feeding them; subtitles built not from my script but from what was actually said on screen; a design system I generated with a single prompt, and packaging rendered in Remotion. Plus an honest look at the numbers — twelve dollars a clip and 22% full-watch retention.
ReadKeeping the same characters across AI clips: universal elements instead of the first frame
In episode two of "Sheriff Potato" the cast grew, and the first-frame trick stopped carrying it — to keep characters from drifting between scenes I moved the canvas to references, my "universal elements". Inside: why video models force you to choose between a first frame and elements (and why Kling is the exception), what 8 seconds cost on Grok, Gemini and Seedance, the 480p trick, ImageRef tags and characters' distinguishing marks. Plus an honest look at scene-six bugs — and the finished episode at the end.
ReadMy node canvas for video: building a whole clip on a single graph
The first three parts took the pipeline apart piece by piece — the LLM for the scriptwriter, the video model, the storyboard. Here I show the whole canvas at once: my own node editor on litegraph and the ComfyUI core, where Claude writes the script, characters live as reusable "souls", and the "one frame → video" trick holds a scene's opening. Plus the first clip the canvas assembled on its own, and the "cabbage hat" bug that taught me the most.
