AI-First Engineering

We help companies build with AI — from strategy to production.

LLM integration, intelligent automation, AI-powered products, and scalable infrastructure.

What We Do

From AI strategy to production deployment — we bring deep engineering expertise to every engagement.

AI Strategy & Consulting

Identify high-impact opportunities to integrate AI into your products and workflows. We assess feasibility, design architecture, and build roadmaps.

LLM Integration

Build production-grade applications powered by large language models. RAG pipelines, prompt engineering, fine-tuning, and evaluation frameworks.

AI-Powered Products

End-to-end development of AI-native products — from intelligent search and recommendation engines to autonomous agents and conversational interfaces.

MLOps & Infrastructure

Scalable ML infrastructure, model deployment pipelines, monitoring, and observability. Cloud-native architecture on AWS, GCP, or Azure.

Scalability & Performance

Deep expertise in PostgreSQL, Redis, distributed systems, and high-throughput architectures. We make applications fast and resilient.

DevOps & Automation

CI/CD pipelines, Docker, Kubernetes, infrastructure as code. Automate everything from development environments to production deployments.

Public Speaking

Talks and presentations on software architecture, Ruby, DevOps, concurrency, and scaling distributed systems.

Inquirex: Deterministic DSL meets Probabilistic LLM

Inquirex: Deterministic DSL meets Probabilistic LLM [2026]

Presented on April 14th, 2026 at SF Ruby User Group, this talk introduces a collection of gems that together define flexible DSL for building deterministic lead-qualification forms that are type-safe, supporting AST branching supported, TTY interface, HTML interface, and LLM acting as an extractor of answers from free-form text, shortening the process dramatically.
