AI Engineering

We train models on your data and ship them into production. From prototype to production—LLMs, RAG, and agents that deliver real business value.

  • Custom LLMs and fine-tuning on your domain data
  • RAG: retrieval-augmented generation for grounded, accurate answers
  • Agents that run autonomously and orchestrate complex workflows
  • Prompts tuned for your use case—consistency, safety, and performance
  • LLMOps: monitoring, versioning, A/B tests, and redeploys
  • Vector stores, embeddings, and semantic search at scale

Data Engineering

Your data flows in. Clean, queryable, ready for models. We build pipelines that scale from prototype to enterprise—streaming, batch, or hybrid.

  • Streaming pipelines with Kafka, Flink, or managed services
  • Batch ETL and orchestration with Airflow, Prefect, or custom
  • Data lakes and warehouses—Snowflake, BigQuery, Redshift, Databricks
  • Quality checks, profiling, and lineage for trust and compliance
  • ML feature stores for reproducible, production-ready features
  • Schema evolution, incremental loads, and idempotent pipelines

Cloud & DevOps

Run it anywhere. Deploy in minutes. Sleep at night. We build and operate infrastructure that scales—multi-cloud, on-prem, or hybrid.

  • AWS, GCP, Azure—or all three with a unified approach
  • Kubernetes, containers, and serverless—pick the right fit
  • CI/CD pipelines that actually work—fast, reliable, observable
  • Terraform, Pulumi, and IaC for reproducible environments
  • Hardening, security audits, and compliance readiness
  • Cost optimization, autoscaling, and disaster recovery
AWS GCP Azure Kubernetes Terraform

Web & Mobile Product Development

Full-stack web apps and Flutter mobile applications for iOS and Android — where AI is part of the product, not an add-on. From idea to launch: frontend, backend, APIs, and AI-native UX.

  • Web apps — React, Next.js, Flask, FastAPI, Node.js, and REST APIs
  • Mobile apps — Flutter for iOS and Android (e.g. Aadhya Self Drive on App Store and Google Play)
  • AI wired into the UX from day one — chat, copilots, and intelligent flows
  • Shipped end-to-end with clear scope and handover documentation
  • Scalable from MVP to enterprise — architecture that grows with you
  • Design systems, auth, third-party integrations, and real-time features
