ZİFT — Umut Sever · evidence over adjectives Build. Measure. Verify.

01 / STATEMENT

Claims are not proof.

I'm an incoming first-year Econometrics (Ekonometri) student at Bursa Uludağ University — classes begin 28 September 2026 — building toward data engineering: pipelines, contracts, run ledgers, and evidence pages that anyone can open and audit.

My rule is narrow and unforgiving: a project counts only when it has a public artifact, a green pipeline, and an honest limitations section. Where a claim can't be verified, the page says so out loud — including missing scheduled days and synthetic-fixture modes.

The other half of my brain writes renderers from scratch: raw WebGL2 with hand-written GLSL, zero runtime dependencies, plus a UE5 racing sim. Data pipeline or fragment shader — no black boxes either way.

class UmutSever:
    school     = "Econometrics (Ekonometri) @ Bursa Uludağ University"
    alumni     = "Tofaş Science High School"
    location   = "Bursa, Türkiye"
    target     = "AI & Data Engineering — verified milestone by milestone"

    building   = ["econ-lakehouse", "pulsegrid", "ekodiff", "cosmic-econometric-observatory"]
    learning   = ["PostgreSQL at depth", "Docker", "AWS DEA-C01", "time series"]
    edge       = "Zero-dependency WebGL2 / GLSL · UE5 · Blender"

    philosophy = "Tested > claimed. Deployed > demoed. Evidence > adjectives."

Open them. They run in your browser.

Every link below was reachable at the time of writing — no screenshots, no promises.

Experience What it is Live
SEVER/05 — Portfolio Editorial case-study site: ownership, key decision, and the line between tested and deployed umutseve4.github.io
PulseGrid 3D A cinematic data-reliability city in Three.js — failure → quarantine → replay → recovery, with a full accessible table equivalent when WebGL is unavailable open
Kozmik Ekonometri Rasathanesi 144 real course records, 147 nodes / 146 edges, every row carrying source id, line position and SHA-256 digest open
Tercih Atlası 2026 Explainable decision surface for 20 career fields — score = 0.30F + 0.25G + 0.20I + 0.15X + 0.10E, stated as an editorial model, not advice open
Çanakkale 1915 Single-file Three.js cinematic scene — a commemorative sequence, not a game; motion respects prefers-reduced-motion open
EkoDiff — Akademik Zaman Makinesi Curriculum version diffs and a local-first what-if engine; nothing about a student leaves the browser open
econ-lakehouse — run evidence Static page rendered from an append-only Parquet run ledger; missing days are shown, not hidden open

03 / SELECTED SYSTEMS

Work with receipts.

▸ econ-lakehouse

Medallion lakehouse for Turkish macro data

  • Python ingest → Parquet bronze → dbt + DuckDB silver/gold
  • Data-quality gates between every layer
  • Scheduled via GitHub Actions, each execution appended to a Parquet audit ledger
  • Evidence page states its own scope: runs use a committed synthetic fixture — it proves orchestration, not upstream data freshness

Python dbt DuckDB Parquet Actions

→ Repo · → Evidence

▸ enflasyonum

Personal inflation index vs official TÜİK CPI

  • FastAPI + PostgreSQL pipeline, deployed on Render
  • Laspeyres index across 13 ECOICOP sub-indices — explainable and CPI-comparable
  • Autonomous daily ingest + watchdog workflow
  • Test suite, live smoke-test workflow, CSV export, SVG summary cards

Free tier: the first request wakes the instance, so give it a moment.

Python FastAPI PostgreSQL Render

→ Repo · → Live

▸ MakroQuest

Economics detective game on real data

  • LangGraph agent + pgvector retrieval
  • Real EVDS / TÜİK macroeconomic series
  • Every clue cites its source — evaluation sits beside generation so unsupported answers can't hide

Python LangGraph pgvector RAG FastAPI

→ Repo

▸ PulseGrid · PulseGrid 3D

A data-reliability lab you can watch

  • Observable streaming pipelines: contracts, quarantine, replay, lineage, SLOs
  • The 3D city is not decoration — height maps throughput, light density maps utilization
  • No WebGL? The full telemetry survives as text.

Python TypeScript Three.js data quality

→ Lab · → 3D

▸ Cosmic Econometric Observatory

Provenance-first curriculum world engine

  • Deterministic knowledge graph: 147 nodes, 146 edges, 144 course records
  • Each course carries source id, view id, line position, SHA-256 digest
  • Canvas is never the only information surface — HTML + SVG keep an equal identity set

TypeScript provenance a11y

→ Repo · → Live

▸ EkoDiff · Akademik Zaman Makinesi

Versioned curriculum snapshots + local-first what-if engine

  • Diffs curriculum versions so a change is visible, not rumoured
  • Runs locally in the browser; no student data leaves the device
  • Independent student project — not an official university service

JavaScript local-first verify CI

→ Repo · → Live

▸ homefront-universe

Universe-scale space RTS, zero dependencies

  • Raw WebGL2 + hand-written GLSL, procedural ship meshes, generative textures, GPU instancing
  • Headless deterministic simulation path
  • Frames stamped with engine-state checksums — reproducible, not decorative

WebGL2 GLSL JavaScript

→ Repo

▸ Çanakkale 1915 · Gallipoli 1915

Commemorative WebGL sequences

  • Single-file Three.js scenes — no build step, no bundler, no tracking
  • Turkish and English editions kept as separate surfaces rather than a language toggle bolted on
  • Reduced-motion path is a real path, not a disabled animation

Three.js WebGL a11y

→ TR · → EN

▸ UludagFormula

Original 3D racing sim

  • Unreal Engine 5.8 + Blender 5.2 LTS
  • Custom vehicle physics
  • Python-scripted editor automation

UE5 Blender Python C++

→ Repo

▸ ZİFT — brand system

One vector master, every raster generated

  • brand/zift.svg is the only hand-authored file; CI renders 17 files into brand/ plus the repo-root favicon, 18 in all
  • A legibility gate measures the signal-red slits at 32px and fails the build if the mark stops reading
  • Icons and link previews are injected into the site head by the same workflow, so surfaces cannot drift
