• Diagnosed and restructured 15+ legacy PostgreSQL queries through targeted indexing, query plan analysis, and rewrite strategies, reducing API response times by 96% (15 s → 500 ms) across live municipal datasets.
• Designed and deployed multi-threaded Quartz Scheduler jobs to pre-compute municipal analytics overnight, cutting peak-hour server load by 45% and eliminating on-demand computation bottlenecks for 10M+ records.
• Delivered a full backend overhaul of a large-scale civic platform within a strict 2-month deadline, coordinating with cross-functional teams under production SLA pressure with zero critical post-deployment defects.
• Architected transactional REST APIs using Spring Boot and jOOQ to orchestrate complex multi-unit property state transitions, ensuring full ACID compliance across concurrent requests.
• Built a thread-safe, concurrent PDF generation engine using OpenPDF capable of rendering 10,000+ municipal certificates daily under high concurrency without data corruption or race conditions.
• Implemented asynchronous batch data synchronization workers, eliminating 40% of manual data processing overhead and automating weekly reconciliation cycles across distributed data stores.
• Architected and executed backend migration of a legacy monolithic recruitment system to a Spring Boot and Apache Kafka-based event-driven microservices architecture, improving system scalability and maintainability.
• Ensured 100% data integrity and zero data loss during schema transformation and migration of 500,000+ applicant profiles across distributed services — validated through automated reconciliation scripts.
• Built high-performance geocoding REST APIs using PostgreSQL with PostGIS extensions to ingest, validate, and store GPS-tagged property coordinates at municipal scale with sub-second validation latency.
• Engineered voter data ingestion pipelines with strict ACID transaction compliance, ensuring reliable and auditable electoral record processing under high-volume batch loads.
