- Apple Maps Via ThoughtGenesis As Software Engineer - Designed, build and maintained large-scale batch data pipelines(Spark) that process geospatial data and automate quality improvements across many international markets. - Improved the performance, reliability and observability of distributed workflows by fixing memory and checkpointing issues, tuning long-running jobs and improving error reporting. Migrated legacy workflows to cloud-native, container-orchestrated infrastructure. - Implemented rule-based validation, auto-correction and anomaly-suppression logic that reduces noise and manual review effort for downstream data editors. - Partnered with data scientists and ML teams by building the pre-processing, post-processing and label-generation pipelines that feed their models, and by handing over the work through knowledge-transfer sessions. - Triage and root-cause production failures end to end, from orchestration through compute to the data itself, and shipped fixes with clear documentation. - Explored LLM-assisted engineering workflows with Claude Code. This includes agentic tooling, MCP integrations and plugins that automate pipeline diagnostics and issue-tracking tasks, and summarising large volumes of project history and automated post development testing by-passing QA team approval and rpviding better results in testing developed changes. - Tech Stack : Scala, Spark Core, Spark GraphX, AWS EMR, AWS EKS, AWS S3.

About

Data engineer working on large-scale geospatial data pipelines. I build reliable, configurable Spark-based workflows that turn raw signals into high-quality map data across global markets. I work closely with data scientists and ML teams on feature extraction, labelling and model-ready pipelines. I'm also exploring how GenAI and agentic tools, such as Claude Code, MCP servers and custom plugins, can speed up debugging, diagnostics and day-to-day engineering work.
