Hands-on architectural design and implementation across four core engineering pillars. Built for founders, CTOs, and product teams needing senior ownership over production software.
End-to-end engineering of scalable B2B and consumer SaaS platforms. Multi-tenant database schemas, Stripe/Razorpay recurring billing, enterprise RBAC, and responsive Next.js web applications.
Deterministic, audited Retrieval-Augmented Generation engines with hierarchical semantic chunking, PostgreSQL pgvector HNSW indexing, cross-encoder reranking, and verbatim citation verification.
Native-feeling mobile apps engineered with custom Swift/Kotlin native bridges, patented low-power background geolocation, offline MMKV state caching, and automated Fastlane CI/CD releases.
High-throughput API microservices built with Node.js, NestJS, and Express. BullMQ asynchronous worker queues, Redis hot-caching, atomic idempotent webhook processing, and AWS deployments.
Codebase health audits, database bottleneck profiling, cloud infrastructure cost reduction, and fractional technical leadership for startups and founders at critical engineering crossroads.
