Building an Internal Developer Platform: From Jenkins to Self-Service CI/CD

Submitted Oct 17, 2025

Session type: Talk (30 mins)

Session Abstract

When your Internal Developer Platform’s CI/CD infrastructure becomes a developer productivity bottleneck—5 instances, 2-3k builds daily, $50k annual costs, and compliance gaps—you need a platform engineering approach that works. This session covers our real-world journey from Jenkins to GitHub Actions, focusing on how we built a self-service, scalable IDP that empowers developers while maintaining enterprise-grade governance.

We’ll dive into the platform engineering challenges: creating standardized, reusable workflows across 15+ languages and build tools, implementing secure secret management with customer-level isolation, and building a centralized IDP that enforces standards through developer-friendly abstractions. You’ll learn how we leveraged self-hosted Kubernetes runners as our platform foundation, maintaining existing infrastructure while gaining GitHub’s native audit logging and access controls for ISO27001 compliance. We’ll also cover our approach to reliability & observability as platform capabilities, cost efficiency through FinOps practices, and security by design in our platform architecture.

The IDP results speak for themselves: improved developer velocity (50-60% faster builds), enhanced developer experience (self-service debugging, unified tooling), reduced platform operational overhead (50% reduction in on-call tickets), and a centralized gating mechanism that scales with developer autonomy. We’ll also share our unexpected wins—how the migration enabled us to create an IDP that standardizes developer practices while enabling inner-source contributions through GitHub Actions’ modular design, plus measurable cost savings through FinOps optimization.

Whether you’re building internal developer platforms or evaluating modern CI/CD solutions, this session provides practical insights from a successful platform engineering transformation.

Key Takeaway

  • Internal Developer Platform (IDP) Adoption: How we built an IDP that developers actually want to use, with adoption metrics and impact measurement
  • Platform Foundations: Kubernetes as our platform foundation with hybrid models, self-hosted runners, and infrastructure reuse strategies
  • Platform as a Product: Developer adoption strategies, success metrics, and measuring IDP impact on developer productivity
  • Reliability & Observability as Platform Capabilities: Building observability into the platform itself, not just the applications
  • Cost Efficiency & FinOps: How we achieved measurable cost savings through platform optimization and resource management
  • Security by Design: ISO27001 compliance, audit logging, and security controls built into platform architecture from day one
  • Provisioning & Lifecycle Management: Multi-language, multi-architecture build platform (15+ languages) with standardized developer interfaces
  • IDP Lessons Learned: What we’d do differently and critical success factors for similar IDP transformations

Target Audience

  • Platform engineers building internal developer platforms
  • Platform engineering teams evaluating modern CI/CD solutions
  • Engineering leaders investing in developer productivity platforms
  • Platform architects designing scalable developer experiences
  • Developer experience teams focused on self-service capabilities

About You

I lead the CI/CD charter at InMobi, where I oversee our Internal Developer Platform and developer tooling. Over 6 years, I’ve worked on scaling our platform foundations to support a growing engineering team. This IDP transformation project was one of our most impactful platform engineering initiatives.
