Ganeshguru A

Full-stack developer

I build web and mobile products that run in production — real-time tracking, payments and APIs that hold up under real users. Two years shipping, two apps live on Google Play.

Also building with AI

I use Claude Code as a daily engineering tool — this site and both of my published Agent Skills were built with it — and I'm comfortable going further: wiring LLM APIs into real products, retrieval over a vector store, and fine-tuning a model when prompting alone isn't enough.

What I actually do

I work across the whole stack — React and Next.js on the front, Node.js and PostgreSQL behind it. Most of my time goes to the unglamorous half: securing endpoints, trimming redundant network calls, and getting queries fast enough that the interface never has to apologise for waiting.

Before that I spent two years on mobile, migrating a fitness platform from web to React Native and keeping it stable on both Android and iOS. That work taught me to treat performance and offline behaviour as features, not afterthoughts — which is how I still build.

Agent Skills I've published

Agent Skills are portable instruction packs that change how a coding agent works — versioned, reviewable, and installed per repository. I've published two, each shipped with behavioural evals rather than just prose. Both are installed in this portfolio's own repository, so the site you're reading is also the test case.

Agent skillv1.0.0 · MIT

stack-aware-development

Read the repo before you change it

Stops an agent reaching for its favourite stack. It detects the languages, frameworks, database and test tooling from lockfiles and manifests, copies the conventions of the nearest existing feature, then makes the smallest change that fits — and verifies it with the project's own commands.

zod-schema-architect

Design the contract, then write the schema

Treats a Zod schema as a runtime contract at a trust boundary, not a type echo. It finds the boundary, decides whether runtime validation is warranted at all, reads the repo's installed Zod version and existing conventions, then writes the schema, the inferred types, the integration and the tests.
