Senior Data Architect

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

    / optimize

    02

    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

    / stream

    03

    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 · Audit

    One 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 · Architect

    Target 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 · Build

    I 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.
