Rahul Dev Garg 👋
Backend & Platform Engineer | Systems Thinker | Builder
I design and operate backend and platform systems that hold up under scale, failure, and scrutiny.
My work lives at the intersection of API boundaries, data flow, reliability, and long-term operability.
I prefer boring systems that behave predictably. Chaos is easy. Engineering is not.
👀 Engineering Focus
- Distributed backend systems and platform architecture
- API and data contract design (REST, GraphQL)
- Event-driven and asynchronous system design
- Reliability, failure modes, and operability
- Internal developer platforms and tooling
- Modernization of legacy systems without reckless rewrites
🌱 Currently Exploring
- AI-assisted system documentation and architecture generation
- Automated code → diagrams → printable system docs
- Event-driven and streaming pipelines under partial failure
- Raspberry Pi–based edge, networking, and server infrastructure
- Platform-style deployment models and lightweight orchestration
- Redesigning mission-critical legacy UIs with modern design discipline

🏢 Professional Experience
Senior Software Engineer — American Express
Apr 2024 – Present
- Designed and owned a data publication platform using Kotlin and BigQuery
- Defined contract-driven APIs (GraphQL + REST) to reduce producer–consumer coupling
- Applied event-driven patterns to handle bursty workloads and downstream backpressure
- Built internal service templates and CI/CD automation for standardized deployments
- Made architectural trade-offs across cost, latency, security, and operability in a regulated environment
Software Engineer — 91Social
Aug 2021 – Mar 2024
- Designed service-oriented backend systems for modular consumer applications
- Built production mobile apps with clean API boundaries and separation of concerns
- Developed configurable backend workflows with extensible, event-driven interactions
- Contributed to DIGIT DPG, a government platform supporting rural utilities across states
- Introduced ownership discipline and backlog hygiene to reduce unresolved work
Software Engineer — zebo.ai
Sep 2019 – Feb 2021
- Built backend services for digital patient management and scheduling
- Translated ambiguous product requirements into maintainable backend systems
- Worked closely with stakeholders to define realistic system boundaries
🔬 Independent Systems Work
- Experiment with container runtimes and lightweight orchestration
- Explore event-driven and reactive pipelines under load and partial failure
- Work with protocol-level communication (gRPC, WebSockets)
- Maintain architecture notes and system design documents
- Use personal projects as a sandbox for applied distributed systems learning
🧭 Architecture & Leadership
- Lead system design discussions with focus on boundaries and failure modes
- Define API standards, versioning strategies, and service ownership models
- Mentor engineers toward systems thinking over feature thinking
🎓 Education & Certification
B.Tech — Computer Science
GLA University, Mathura (2021)
Professional Google Cloud Architect — Google Cloud
💞️ Open to Collaborate On
- Backend-heavy or platform-centric products
- Internal developer tooling and infrastructure platforms
- AI-powered documentation and system visualization
- Legacy system modernization done responsibly
- Open-source projects with real operational constraints
If the system needs to survive real users and real failures, I’m interested.
