Remote, Singapore

Senior Software Engineer

Key Responsibilities & Achievements

• 🗄️ Led database migration from SelectDB (OLAP) to PostgreSQL (OLTP) for lead-gen data: Sales dashboard querying transactional data from data warehouse caused 15s+ load times. Analyzed data-access-pattern, proposed the architectural change and executed zero-downtime migration. Reduced load time to under 200ms - 75x performance improvement & 99% latency reduction

• 📊 Built job-analytics feature: Designed the API and DB schema to compute application and conversion metrics across jobs over a max 180-day window. For clients with 2,000 jobs requesting data for 180d, it meant aggregating 360,000 rows. Implemented hash-based caching using job IDs + time periods as keys for sub-1-second responses

• ⚡ Implemented selective PostgreSQL read-replica routing: Primary database at 85%+ CPU with no application-level replica routing. Instead of “all reads to replica” (which breaks “read-your-writes” consistency), I opted for a hybrid approach where queries default to primary, developers explicitly route non-critical reads to replica. Reduced primary DB’s CPU load to ~60%

• 💳 Redesigned employer credit system from aggregated to individual expiry tracking: Migrated from single balance (expiry kept extending) to granular tracking of free vs paid credits with individual expiry. Two-phase backward-compatible migration - Phase 1: new schema with dual-write and backfilling, Phase 2: migrated backend operations while maintaining legacy APIs for older mobile clients. FIFO deductions with row-level locking to prevent race conditions. Coordinated changes across backend, web, mobile, and internal platforms. Impact: 3-month free credit expiry instead of indefinite, driving revenue

• 🚀 Optimized Instagram lead-gen pipeline from 8 hours to 20 minutes: Refactored a sequential pipeline to leverage concurrency for I/O-bound async operations, reducing runtime by 24x while maintaining lead quality. The faster execution enabled more frequent batch runs and increased daily lead throughput

Software Engineer 2

Key Responsibilities & Achievements

• 📝 Designed and implemented an extensible job hiring questions and screening system with customizable multi-question flows, enabling employers to filter candidates by responses and driving significant business impact by boosting employer responsiveness from 7.5% to 18.2% (+142.7%)

• 🌳 Contributed to foundational product transformation by migrating job categories and locations from legacy flat structures to multi-level hierarchical taxonomy using MPTT (Modified Preorder Tree Traversal) in PostgreSQL. Initially launched for Indonesian platform users impacting 6M+ users and 330K+ job postings, the solution significantly improved job search accuracy and recommendation quality, prompting adoption across Vietnam and Singapore platforms. Subsequently managed bi-annual taxonomy maintenance and updates

• 📈 Proposed and led observability improvements with Kibana dashboards and Grafana alerting, reducing errors on mission-critical endpoints from 7% to 0.5% and some endpoints achieving up to 10× latency improvements (from 3s to under 300ms) through proper indexing and query optimizations

• 🔍 Investigated and permanently fixed a critical race condition in Elasticsearch job indexing pipeline that deleted a promoted index which took down core job search feature for 17 minutes. For familiarity this was a scenario similar to the race condition that caused the deletion of a DNS record leading to the AWS US-EAST-1 outage in Oct 2025

• 🏆 Recognized as a go-to engineer for deep debugging and root-cause analysis, collaborating across teams to resolve complex production issues and implement long-term stability improvements

• ☁️ Proposed and led the application-level migration plan from AWS S3 to Alibaba Cloud OSS, ensuring zero downtime and full backward compatibility for mobile apps. Part of company-wide AWS-to-AliCloud transition aimed at achieving 35–40% annual infrastructure cost reduction
