About

Permadi Afrian — Software Engineer, 8+ years, Central Java, Indonesia.

I'm a product-minded software engineer across frontend, backend, and mobile. I turn ideas into clear designs and reliable software, favoring maintainable code, thoughtful docs, and practical architecture. I collaborate with product and design, own features end to end from discovery to delivery, and leave teams with systems that are easy to operate and evolve. I care about performance and developer experience, choosing simple solutions that scale when needed.

Open to senior engineering roles and selected consulting engagements.

Experience

1. Software Engineer

   Podifi · United States

   Aug 2025 — Present

   Systems owned

   • Full-stack delivery across concurrent client projects
   • TypeScript services on AWS (Lambda, KMS, SQS)
   • POS mobile enablement (.NET MAUI)
   • LLM data-processing flow (LangChain)

   Blast radius

   Production delivery across concurrent client projects rather than a single owned system; work ships to production, so a defect surfaces in a live product rather than an internal environment.

   • Works across the full stack and across projects rather than owning one service, in a delivery organisation that staffs engineers onto whichever product needs them.
   • Turns PRDs into concrete design proposals and ships approved changes with end-to-end testing.
   • Uses agentic development workflows as a standard part of delivery, holding production-grade quality while shortening the path from proposal to shipped change.
   • Contributes to a mobile enablement initiative for a POS platform using .NET MAUI, porting core desktop workflows to mobile.
   • Implemented an LLM-powered data-processing flow using LangChain, integrated cleanly into existing service workflows.
   • Documents key decisions and changes so future iterations are fast and low-risk.

2. Software Engineer III

   Geniebook · Singapore

   Nov 2021 — Aug 2025

   Systems owned

   • Class platform (live and on-demand)
   • Four extracted Go microservices
   • React live-class client

   Blast radius

   The live-class platform serving ~1,500 concurrent students; an outage stops classes in progress.

   • Owned the Class platform and shipped interactive live-class features at ~30 simultaneous classes of ~50 students each.
   • Led the extraction of four Go microservices from a PHP/MySQL monolith, introducing gRPC, Kafka, and Postgres.
   • Partnered with DevOps to move Kubernetes workloads from GCP to AWS, cutting infrastructure costs by ~30-40%.
   • Standardized local development with Docker, cutting new-machine setup from ~4-6 hours to ~10-30 minutes.
   • Mentored four engineers on Go, microservices, and streaming, reviewing ~10-20 PRs per week.

   • Breaking up a PHP monolith without taking the platform down
   • Replacing Zoom with a streaming stack we ran ourselves

3. Software Engineer

   PT. Pan Brothers Tbk and Group · Boyolali, Indonesia

   Sep 2018 — Nov 2021

   Systems owned

   • Production monitoring system (~3 plants, ~30 lines)
   • Warehouse data system
   • CI/CD across six repositories

   Blast radius

   Production monitoring for ~3 plants and ~30 lines used by 20+ stakeholders; stale data means line problems go unnoticed.

   • Built a production monitoring system used across ~3 plants and ~30 lines by 20+ stakeholders.
   • Integrated real-time telemetry from >100 machines (~150 msgs/sec) into a unified dashboard.
   • Migrated legacy apps to Laravel, cutting P95 page load times by ~40% and post-release defects by ~80%.
   • Implemented CI/CD for six repositories, reducing deployment time from ~1-2 hours to ~5-10 minutes at ~99% success.

   • Making a factory floor observable in under a minute
