DATA ENGINEER / GEOSPATIAL SYSTEMS
I build reliable data pipelines across batch, streaming, cloud, and geospatial systems. 4+ years of experience.
EARTH OBSERVATION
From source signals to trusted systems.
THE ENGINEERING BEHIND THE OBSERVATION
GEOSPATIAL DATA ENGINEERING
Select a stage to trace the engineering.
Six engineering responsibilities, one connected system. Select a stage above to explore the verified implementation.
An original observation spacecraft connects source acquisition, validation, transformation, governance, storage and serving. The interactive scene is optional; the evidence remains accessible below.
SELECTED WORK / VERIFIED SYSTEMS
Three verified projects show distributed processing, dimensional modeling, data-quality controls, and honest system boundaries.
01 / FLAGSHIP
A governed NASA FIRMS platform preserving source truth, deterministic lineage and replay-neutral analytics.
View project case study ↗Explicit limit AWS 10M not executed. Spacecraft, solar activity and acquisition signals are illustrative, not measurements or live mission data.
02 / SUPPORTING
PostgreSQL dimensional warehouse loading 400,000 sales facts across five source domains, with tested SCD Type 2 dimensions, quarantine, and repeat-safe loading.
20 analytical SQL queries · 20 automated tests · hosted CI passed
03 / SUPPORTING
Deterministic local batch ETL with a separately verified 100,000-order run, transactional SQLite snapshot replacement, and invalid-measure quarantine.
6 local tests passed · hosted CI passed on a 1,000-row fixture
An interactive cybersecurity professional portfolio for Mukesh Chanambatla, built by ASTRAYAN Web Studio. Web craft, not a data-engineering evidence system.
