Summary
Software engineer with 2+ years of experience building production Digital Public Infrastructure at Dhiway: two-sided job networks on ONEST/Beckn, schema-driven Digital Public Goods, and privacy-preserving identity (Aadhaar OVSE, W3C Verifiable Credentials, CORD). Builds backend services in Rust (Axum, Tokio, SQLx, gRPC) and TypeScript (Fastify, PostgreSQL, Redis), web frontends in React and Next.js, and cross-platform mobile apps in React Native and Expo, from credential wallets to client-specific apps built to each customer's requirements, with a focus on on-device security and ProGuard/R8-optimized release builds.

Experience
Software Engineer · Dhiway Networks Pvt. Ltd.
Dec 2024 – Present · Bengaluru, India- Shipped Jobstack seeker and provider backends (Fastify, TypeScript, PostgreSQL, Redis, Better Auth) for a two-sided jobs marketplace on ONEST/Beckn: phone/email OTP, org RBAC, API keys, Redis session tracking, and Beckn search/select/init/confirm/status.
- Supported Hubli-Dharwad and Ghaziabad pilots, including dial-flow APIs so voice/IVR agents can create profiles and post jobs.
- Turned Jobstack into Signals DPG (Blue Dots Economy), a schema-driven Digital Public Good with Postgres multi-level LIST partitioning, inter-instance HMAC fetch, consent-gated discoverability, and PII location jitter. Wrote the blue_dot (jobs) and yellow_dot (education) network schemas.
- Built a provider-agnostic notification service (Fastify + Redis queues, HMAC request signing, retries/DLQ) for email, SMS (MSG91) and WhatsApp, wired into signup, application and OTP flows.
- Architected an OpenID4VP-compliant credential verification service in Rust using Axum, spruceid/openid4vp and rustls, verifying ISO 18013-5 mDL credentials with sub-15 ms p99 latency.
- Built Eumi, an Aadhaar OVSE identity stack: Rust gRPC trust service (Secure QR, SD-JWT, mAadhaar app intent), Fastify core with AES-256-GCM evidence (raw Aadhaar never stored), Expo wallet, and DigiLocker-to-VC issuance.
- Built OpenClaims, a Rust/Axum credential node implementing OpenID4VCI and OpenID4VP with DID and a CORD trust/status bridge for issuer accreditation and revocation.
- Built cross-platform credential wallets in React Native/Expo for Eumi and for farmer W3C VCs with selective disclosure, with a focus on on-device security and ProGuard/R8-optimized Android release builds.
- Contributed to CORD (Substrate/Rust), including the SDK v1.22 runtime upgrade (99 files), cord.js registry/entry lifecycle scripts, a WAY-token faucet, and on-chain sync of job postings.
