AI Engineering & Intelligent Systems
Production LLM integrations, RAG architectures, and agentic automation with reliability.
LLMs are probabilistic, but business software requires deterministic outcomes. I build production AI platforms using Finite State Machines, strict Zod schema validation, semantic vector caching, and sandboxed tool execution to prevent hallucinated data and API cost runaway.
Engineered for Deterministic Production AI
- LLM outputs failing JSON parsing, hallucinating database fields, or producing invalid API payloads.
- API cost runaway due to un-cached redundant prompts and large uncompressed context windows.
- Needing autonomous AI agents that operate with safe, human-in-the-loop fallback mechanisms.
Execution Architecture
Finite State Machine LLM Wrappers
Structuring AI interactions into deterministic state transitions with strict Zod validation.
Semantic Prompt & Vector Caching
Implementing semantic cache layers (reducing token costs by 40%+ and cutting latency).
Retrieval Augmented Generation (RAG)
Designing hybrid keyword + vector retrieval engines for accurate context injection.
Sandboxed Tool Execution & Guardrails
Restricting model actions to strictly validated database intents and API boundaries.
Core Technical Stack & Tooling
Investment & Engagement Terms
AI Engineering engagements start at $15,000 for custom LLM integrations and upwards of $40,000 for full enterprise agentic platforms.
Trusted Across Critical Deployments
Verified client testimonials from founders and engineering directors who relied on Shubham's systems.
"Shubham stepped in when our internal team was bottlenecked. He re-architected our high-concurrency ingestion pipeline in three weeks and handed over production-ready software with flawless documentation."
Marcus Vance
Chief Technology Officer • Apex Cloud Systems (San Francisco)
"شبھم کے ساتھ کام کرنے کا تجربہ بے مثال رہا۔ انہوں نے ہمارے اسکیل ایبلٹی کے پیچیدہ مسائل کو انتہائی مہارت اور رفتار سے حل کیا، اور پورا سسٹم وقت سے پہلے مکمل کیا۔"
Tariq Mehmood
Chief Technology Officer • FinStack Systems
"Shubham a repensé notre architecture distribuée en quelques semaines. Sa capacité à transformer des exigences système complexes en code haute performance est exceptionnelle."

You own the system.
The code. The infra. The data.
Software should not become valuable enough to matter and then be impossible for the client to own or operate.
Everything I build is 100% client-owned intellectual property from day one. You own the code, the accounts, the infrastructure, and the data. No vendor lock-in.
