Selected Projects

PNB SmartLender — Enterprise Lending PlatformAurionpro · 2024 — Present

Technical challenge: Unify the end-to-end loan value chain for Philippine National Bank — SMLC origination, SMLP customer portal, and CLIMS servicing — on a shared platform governed by strict regulatory and operational constraints.
Architecture & solution: Architected fine-grained RBAC (FAP/DAP), multi-level approval chains, and business-rule engines; defined service and API boundaries for Order of Events, collateral, valuation, and pricing; hardened transaction boundaries and optimized Oracle / Hibernate data access (N+1, indexing, query plans).
Impact: Enabled compliant rollout across three systems with maintainable, testable workflow layers and predictable multi-feature release cycles.

Yogiyo — Large-Scale Food Ordering ServiceSotaTek · 2022 — 2024

Technical challenge: 12M+ users, 2M+ DAU, ~10,000 req/s peak; Django monolith bottleneck under scale, with latency, fault-tolerance, and cost pressure.
Architecture & solution: Led incremental migration from monolith to microservices; designed event-driven architecture with Kafka for core ordering and streaming flows, complemented by AWS serverless (SQS, SNS, Lambda) for elastic workloads.
Impact: Reduced API latency by ~35%, cut infrastructure cost by ~25%, sustained ~99.9% uptime with Datadog monitoring and 80%+ test coverage.
