01 How I work

01

Systems that scale

Over five years in backend development, building systems designed to hold up under real production load — not just pass a demo.

02

Problem → plan → production

Good at analyzing problems, creating plans, and designing reliable solutions — then taking them myself from development through deployment.

03

Impact over activity

Focused on processes that get simpler, systems that get faster, and solutions that make a measurable difference for the business.

02 Selected engineering work

Problems owned from RFC to rollout.

PostgreSQLPerformance

−35% DB CPU pressure

Cut database CPU pressure ~35% under financial transaction load

Diagnosed high-volume transaction workloads with EXPLAIN ANALYZE, then applied targeted index tuning, partition-aware queries, and controlled concurrency — stabilizing mission-critical monthly summary and contribution jobs on the Gojek Driver Platform.

GoFintechDistributed Systems

Recurring tech debt → near zero

Re-architected Singapore's CPF contribution system end-to-end

Rebuilt deduction, monthly summary generation, post-verification refunds, and downstream Gojek contribution flows; tightened service synchronization and drove recurring CPF technical debt to near zero.

ComplianceData Pipelines

4 reporting cadences stabilized

Stabilized government-mandated IRAS reporting pipelines

Owned regulatory reporting workflows spanning annual, monthly, weekly, and daily statement pipelines — including driver contribution rate updates, reporting corrections, and financial backfills, with zero tolerance for error.

ReliabilityObservability

−80% log noise

Built the monitoring stack that cut log noise by ~80%

Implemented Hystrix circuit breakers for service resilience and stood up Prometheus, Grafana, Lens, and New Relic for real-time diagnostics — turning reactive firefighting into proactive alerting.

GoFintechQuickBooks API

100% reconciliation · −30% processing time

Built a Go accounting platform with 100% reconciliation accuracy

Designed and deployed an automated invoicing and commission-calculation platform integrating QuickBooks' API for financial record-keeping — cutting data processing time by 30% while hitting 100% reconciliation accuracy across all transactions.

GoPythonIntegrations

40% of manual ops automated

Automated partner data operations end-to-end

Built an FTP synchronization service, an OAuth2-secured Facebook Graph API pipeline for ad-spend analytics, and S3-to-Slack file monitoring — replacing manual, error-prone data handling with reliable, scheduled automation.

GoFiberElasticsearch

Designed a concurrent analytics ingestion API on Elasticsearch

Built a Go Fiber API that parses batched client event data and indexes it into Elasticsearch concurrently — powering real-time visitor analytics across screen, referrer, and session context with structured error handling for reliable ingestion at scale.

MicroservicesPersonal project

Architecting a microservices-based digital marketing platform

An ongoing side project: a multi-portal platform for agencies and clients to plan, execute, and report on marketing campaigns — audience targeting, operations, reporting, and accounting built as independently scalable services.
