Software Engineer Focus

Ainun Abidin Software Engineer with Backend Depth and Product-Building Versatility

I am a Software Engineer who builds reliable backend systems, APIs, and data-driven web applications for real production use. My primary strength is backend engineering, supported by full stack delivery to ship maintainable products end-to-end. I am targeting Software Engineer opportunities first, with strong alignment for Backend Engineer, Full Stack Developer, and Web Developer roles.

Engineering Profile

Software Engineer focused on scalable backend systems, API architecture, and data-intensive web application development. I solve technical bottlenecks with maintainable design, performance optimization, and delivery discipline.

Across enterprise and national-scale initiatives, I have built APIs, spatial services, ETL pipelines, and cloud-ready systems that improved throughput, query efficiency, and operational reliability. I combine engineering depth with product-minded execution, turning complex requirements into production-ready solutions with measurable value.

Featured Engineering Projects

Selected as primary evidence of Software Engineer capability: owning backend architecture, building maintainable systems, and delivering measurable outcomes in production.

Nationwide Survey and Analytics Platform

National survey operations relied on fragmented services, so I built internal backend APIs and analytics workflows to centralize delivery and improve reliability for 1,000+ surveyors and 10,000+ daily transactions.

Role: Backend Engineer 1,000+ surveyors 10,000+ daily transactions 98% KPI compliance

Spatial Search and Routing Engine

Spatial query performance limited product responsiveness, so I designed PostGIS and pgRouting APIs with custom indexing to improve route computation speed and reduce query cost by up to 60%.

Role: Tech Lead / Backend Node.js + Python PostGIS + PostgreSQL up to 60% optimization

Distributed Data Pipeline and ETL Stack

Large payment and infrastructure datasets required faster processing, so I implemented distributed ETL pipelines across Kafka, Beam/Dataflow, and Hadoop to handle 70M+ records with 3x faster throughput.

Role: Backend / Data Engineer 70M+ records 3x faster ETL >70% processing efficiency

Meetup API Modernization and Cloud Delivery

Legacy backend architecture slowed release flow, so I led monolith-to-cloud modernization with RBAC, CI/CD, observability, and media optimization to improve maintainability and deployment consistency.

Role: Software Engineer NestJS + TypeScript AWS + Docker + Nginx GitHub Actions CI/CD
