Shahriar Labs builds custom AI agents, full-stack products, and cloud architecture for startups and enterprises. Here's how we work and what we build.
Shahriar Labs builds custom AI agents, full-stack SaaS products, and cloud infrastructure for startups and enterprises. Founded by Shihab Shahriar Antor, the studio has shipped production AI systems across e-commerce, EdTech, and enterprise SaaS — from single-domain agents to complex multi-agent orchestration systems.
Custom AI agents: Single-domain agents (customer support, lead qualification, document generation) and multi-agent systems (planning + execution + review pipelines, autonomous software development workflows). We build on Claude, GPT-4, and free-model fallback — no vendor lock-in architecture by default.
Full-stack SaaS products: React + TypeScript frontends, Node/Python backends, PostgreSQL/DynamoDB data layers, AWS infrastructure via Terraform. We've built and shipped LetX, Quantum Sketch, and Bikroy Buddy from zero to production.
AI integration: Adding AI capabilities to existing products — LLM-powered features, agent workflows, RAG systems over your existing data. We start with the simplest thing that solves the problem, not the most technically impressive.
Every project starts the same way: scoping call to understand the problem, followed by a written spec that we agree on before any code. No "we'll figure it out as we go." The spec defines inputs, outputs, edge cases, acceptance criteria, and what's explicitly out of scope.
We run a docs-and-tests-first process: spec → IaC → implementation with tests → staged rollout. Every handoff includes documentation that lets your team maintain and extend the system without us.
We don't build: demos that won't scale, "AI wrappers" with no defensible engineering depth, or systems where the core problem is actually a product/market fit question, not a technical one. If your use case is better served by an off-the-shelf tool, we'll tell you. See our custom AI agents vs chatbots guide for the decision framework.
