Architecture decisions, backend systems, and platform engineering work across 7+ years and multiple domains.
Led the complete re-architecture of a legacy CodeIgniter monolith into a Distributed Modular Monolith using NestJS. Domain-driven services run as independent EKS pods while sharing centralized MySQL and Redis, retaining transactional consistency without full microservices complexity.
Designed and implemented the complete database isolation strategy and tenant-scoped data model for a multi-tenant SaaS platform. Built row-level tenant isolation with shared schema architecture to balance isolation guarantees with operational simplicity.
Built the backend payment processing API platform for RNFI, a financial services company. Delivered high-reliability PHP APIs handling transaction workflows, real-time reconciliation, and data integrity enforcement for financial data pipelines in a production environment.
Designed and standardized the API architecture framework across all backend services using DDD principles. Established bounded contexts, domain entity models, aggregates, and service contracts enabling consistent, independently evolvable API surfaces.
Partnered with DevOps to build an observability layer across the EKS-deployed platform. Implemented structured logging, distributed tracing, and alerting strategies. Led production incident analysis and postmortem workflows to improve system MTTR.
Developed backend systems for client-facing web applications using PHP. Designed database schemas, built server-side business logic, and delivered complete backend solutions across multiple client projects — forming the foundational engineering experience.
