Snowflake & Data Platform Architecture
Data platforms built to survive scale.
I'm Yasin Altun — an independent data architect with 13 years across banking, FMCG and high-volume real-time systems. I design, migrate and optimize Snowflake platforms for European enterprises. Directly. No agency in between.

SERVICES
Three ways I make Snowflake earn its invoice.
Every engagement is delivered by me, personally — from the first architecture diagram to the last dbt model in production.
Migrations to Snowflake
/ migrate
01
Legacy Oracle, MSSQL or on-prem DWH moved to Snowflake with zero-surprise cutovers — schema conversion, pipeline redesign, validation frameworks.
Assessment & migration roadmap
ADF / Airflow orchestration design
Parallel-run validation & cutover
Cost & performance
/ optimize02
Most Snowflake bills aren't a warehouse-settings problem — they're an architecture problem. I fix the 80% everyone overlooks.
Workload & credit consumption audit
Clustering, caching, query redesign
RBAC & multi-account governance
Real-time & CDC pipelines
/ stream03
When the business needs minutes, not hours: Debezium, Kafka, Snowflake Streams and triggered Tasks — proven against regulatory SLAs.
CDC architecture (Debezium + Kafka)
Streams & Tasks consumption design
dbt modeling & audit frameworks
HOW I WORK
A short path from diagram to production.
Understand the real system
01 · AuditOne to two weeks reading your platform the way I'd inherit it: workloads, lineage, costs, failure modes. You get a written findings report either way.
Design for the next 3 years
02 · ArchitectTarget architecture, migration or optimization roadmap, and the trade-offs stated plainly — sized for your team, not for a consultancy's billing model.
Ship it, hands on keyboard
03 · BuildI implement alongside your engineers and leave behind documentation, CI/CD and people who can run the platform without me.

ABOUT ME
I've spent my career where data platforms are unforgiving: regulatory reporting at UniCredit Türkiye, a global HR data warehouse for Danone, Snowflake and dbt delivery for Nestlé, and a real-time platform at BrainRocket that I built from the first S3 bucket — now processing 300M+ rows a day under 15-minute regulatory SLAs.
When you work with altAI, there's no bench, no juniors learning on your budget, no account manager. You get the person whose name is on the architecture.

I take on a small number of engagements at a time. First call is a working session, not a sales pitch.
