I’m a software engineer with 10+ years of experience shipping products end to end — from Android (Kotlin) and Next.js apps to GraphQL/Node, Java services, and GCP data pipelines (Spark, Kafka, Airflow, BigQuery, Cassandra).
At Walmart Global Tech I work on the UGC platform (reviews, ratings, media): platform migrations, performance at scale, video/media uploads, and notification pipelines. Outside work I build product — Gatheroly, Swaneet, BillSplit — and write at TechnoRapper.com.
I use this GitHub for learning in public, shipping side products, and sharing reusable ideas with the developer community.
- Full-stack engineer with deep roots in Android / Kotlin and modern Jetpack
- Builds across mobile, web, APIs, and data when the product needs it
- Strong believer in clean boundaries, measurable impact, and long-term maintainability
- Experience designing systems that scale for users, teams, and traffic
- Comfortable with GraphQL, OpenAPI, caching, feature flags, and A/B rollouts
- Actively ships with Next.js, Prisma, Spark/Kafka, GenAI tooling, and system design
- I also run TechnoRapper.com, where I experiment with and write about tech

- Product apps — event SaaS, wedding platforms, fintech experiments
- Android architecture samples, Compose PoCs, and base setups
- Experiments around performance, caching, uploads, and network resilience
- Full-stack work: Next.js, APIs, data pipelines, and AI-assisted tooling
- Notes from real-world engineering: migrations, observability, and DX
- Gatheroly — multi-tenant event platform (owner / vendor / client, RSVP, Connect, face-find)
- Swaneet — cinematic wedding site + admin ops (repo)
- BillSplit — receipt OCR + UPI splits (repo)
- Portfolio & resume — haneetgh.github.io
- Zero-downtime migrations — dual read/write, feature flags, shadow traffic, instant rollback
- Config-driven, decoupled architectures with clear service boundaries
- Systems that are observable, testable, and resilient under load
- Thoughtful handling of network failures, retries, caching, and graceful degradation
- Aligning decisions with developer experience, operability, and maintainability
- Optimized critical paths to cut latency, jank, and redundant downstream work
- Prefer solutions that improve clarity and simplicity, not just raw speed
- Value measurable impact, but avoid premature optimization
- Care about code reviews, design docs, runbooks, and knowledge sharing
- Always open to learning from the community and contributing back
