ASHISH GUPTA
▸ Production RAG · LLM Integration · pgvector
Senior Full-Stack & AI Systems Architect with 10+ years modernizing legacy healthcare and aviation monoliths into decoupled, domain-driven systems and engineering hallucination-resistant RAG platforms.
High-performance Engineering Architect with 10+ years of experience specializing in the VILT Stack (Vue 3, Inertia, Laravel 13, Tailwind). Unique value proposition lies in modernizing legacy Healthcare and Aviation monoliths into scalable, domain-driven systems. Proven track record of reducing cloud infrastructure costs by $1M/year through architectural optimization.
I thrive in fast-moving engineering environments where end-to-end technical ownership matters — taking distributed systems from domain modeling through production hardening, mentoring engineers, and shipping measurable business outcomes.
I architect decoupled modular monoliths with strict bounded contexts, explicit domain events, and zero-downtime strangler-fig migration patterns.
I build intent-aware retrieval engines, hybrid vector embeddings, and autonomous agent loops with prompt defense and fallback safeguards.
I optimize system throughput and sub-50ms latencies with Redis Horizon queue topologies, SQLite WAL concurrency, and proactive OpenTelemetry observability.
I mentor engineering teams, establish automated testing pipelines, author clear architectural RFCs, and transform complex product requirements into resilient production systems.

Verified feedback from engineering leaders, product founders, and domain peers.
“Ashish rewrote a legacy monolith that had defeated three prior teams. He identified the real bounded contexts within a week, and eight months later we were shipping features to a decoupled system without downtime.”
“The RAG pipeline he built for our accountability product runs against WhatsApp with sub-second latency and zero hallucinations we've had to correct. It's the most reliable AI feature we ship.”
“He treats architecture as a communication tool. Every stand-up, the whiteboard photo he sends explains a decision so clearly the whole team can push back or agree on the spot. Cut our architecture syncs by half.”
These case studies walk through real production systems I've designed and shipped: the architectural trade-offs, how I handled high concurrency and scale, and measurable business outcomes. The flagship breakdown reveals how ZoetiCoach AI scaled into a WhatsApp-first autonomous accountability engine.
