   Conduktor - Backend Engineer

   May 2025 – Present

   Scala ZIO Kafka PostgreSQL AWS

   • Worked on data governance and quality features of Conduktor, a Kafka management platform, building backend services for policy enforcement, schema validation and violation reporting.
   • Owned the backend of the Data Quality Overview feature end-to-end: authored the API spec, created and scoped all backend tickets, designed PostgreSQL materialized views to pre-compute complex aggregations, and shipped the full feature in ~2 weeks under tight deadline pressure
   • Built a violation metrics system using PostgreSQL time buckets (minute and hour granularity), including time-series endpoints for graphs and aggregations
   • Resolved a memory leak via JVM heap analysis (jmap + Eclipse Memory Analyser), identified excessive HTTP calls and introduced a caching layer, reducing memory usage from 1.2 GB to 275 MB (4× improvement)
   • Built an AWS MSK Glue Schema Registry Indexer with bounded concurrency and timestamp-based change detection, cutting per-cycle API calls from ~12,000 to near-zero for unchanged schemas
   • Fixed a type preservation bug in the AVRO-to-CEL evaluation pipeline (AVRO -> Java Map instead of JSON), preventing integer values from being silently changed to floats. Filed an upstream bug report on the open-source cel-java library
   • Authored multiple Architecture Decision Records (ADRs) covering DLQ design, JSON Schema validation (avoiding Schema Registry), and rule/policy versioning
   • Led a product release end-to-end: documentation prep, release candidate cut, patch release coordination, and customer-facing communication
   • Implemented JSON Schema enforcement for Kafka message payloads, fixing blocking of valid messages and improving error messaging
   • Rated “4 – Redefines Expectations” in year-end review; recognised for taking ownership of features from investigation through design, implementation, and documentation, and for demonstrating the company value “Own It”
