👋 Hi, I’m Harsh Singhal
🚀 About Me
I’m Harsh, a software engineer who loves turning complex, large-scale problems into elegant, resilient systems.
I started my career curious about how millions of people stream, interact, and trust large platforms every day — and that curiosity has shaped my journey:
- From hacking together IoT projects with Alexa in my early days,
- To re-architecting Amazon Music’s WebPlayer at 1M TPS scale,
- To filing a patent on intelligent caching & DDoS resilience.
What excites me most is building systems that feel invisible yet powerful: the kind that make products smoother, developers faster, and infrastructure cheaper.
Outside work, you’ll usually find me:
- Writing about system design, developer experience, and infra hacks on Medium
- Building experimental tools (like
local-function-proxy and load-shedder)
- Brainstorming startup ideas that merge technology, scalability, and real-world impact
🏆 Things I’m Proud Of
- 📝 Patent Filed (2025): Advanced Caching Service for Dynamic Content Delivery of Videos → bringing intelligence to CDNs & DDoS mitigation
- ⚡ Performance at Scale: Optimized Amazon Music Web to handle 1M TPS while cutting infra costs by 82%
- 🛠 Open Source Creator:
- ✍️ Tech Writer: Articles on latency reduction, Kubernetes CI/CD, serverless structuring, and intelligent caching
- 🤝 Mentor & Builder: I enjoy sharing ideas with other engineers, startups, and teams about scalability and developer experience
🔒 Current Work
I’m currently working on reshaping internet security by proposing a new approach to mitigate cross-site scripting (XSS) vulnerabilities.
This work is being put forward to the W3C as part of a standards discussion, and you can follow the journey in my explainer repo:
👉 XSS Mitigation Explainer (W3C Proposal)
🛠️ What I Work With
- Languages: JavaScript/TypeScript, Python, Go, Java, Swift, Kotlin
- Infra & Cloud: AWS (Lambda, ECS, CloudFront, DynamoDB), GCP (GKE, Datastore), Kubernetes, Docker, IaC (CDK/Terraform)
- Specialties: Distributed systems, CDN optimization, DDoS mitigation, developer productivity tooling, performance engineering
📝 Recent Writing
- Beyond Static: Intelligent Caching & DDoS Mitigation with AWS CloudFront
- Reducing User-Perceived Latency in iOS Using View Lifecycle
- Setup Kubernetes CI/CD for Backend Applications
- Structuring Services for AWS Lambda with Serverless
📌 Beyond Code
I see myself not just as an engineer, but as a builder of systems that empower innovation:
- Helping businesses scale without breaking the bank
- Reducing CO₂ by optimizing infra efficiency
- Enabling developers to move faster with the right tools
My ultimate goal? To keep pushing the boundaries of secure, scalable infrastructure while inspiring others to do the same.
