Custom AI agents, full-stack SaaS products, and cloud infrastructure for startups and enterprises. Founded by Shihab Shahriar Antor.
Single-domain agents (customer support, lead qualification, document generation) and multi-agent systems (planning + execution + review pipelines, autonomous dev workflows). No vendor lock-in architecture by default — Claude, GPT-4, and free-model fallback via openrouter-free.
React + TypeScript frontends, Node/Python backends, PostgreSQL/DynamoDB, AWS via Terraform. We've built and shipped LetX, Quantum Sketch, and Bikroy Buddy from zero to production.
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.
Every project starts with a scoping call and a written spec — not "we'll figure it out as we go." The spec defines inputs, outputs, edge cases, and acceptance criteria before any code. We run a docs-and-tests-first process: spec → IaC → implementation with tests → staged rollout. Every handoff includes documentation your team can maintain without us.
Demos that won't scale. "AI wrappers" with no engineering depth. Systems where the core problem is product/market fit, not technical. If an off-the-shelf tool fits better, we'll say so. See our custom agents vs chatbots guide.
