AI and data platforms that ship to production

I’m Divith Raju, Team Lead for AI Engineering. I design GenAI and multi-agent systems, data pipelines, and the GPU and HPC infrastructure they run on, for clients and vendors who need them to work.

Solutions

Four areas where I take a client from idea to a running, monitored system.

GenAI and multi-agent systems

RAG pipelines, natural-language-to-SQL, and multi-agent orchestration served through FastAPI microservices, with LLM tracing and evaluation.

Data engineering

Batch and streaming pipelines, data lakes and warehouses, with quality checks and cost control built in.

GPU and HPC infrastructure

Cluster scheduling and parallel storage for training and heavy analytics: Slurm, Lustre and other parallel file systems, RAID, JupyterHub, and GPU workloads.

Platform, CI/CD and FinOps

Containerized microservices on Kubernetes, automated build and release pipelines, and cloud cost tracking for warehouses and AI workloads.

Data engineering and AI dashboards

The two views I build for client teams: pipeline health for data engineers, and model and GPU health for AI teams.

Experience and ways of working

I have served multiple clients as a data engineer, and I now lead AI engineering. I work in Agile Scrum sprints with Kanban boards, so vendors and clients see progress every week.

Team Lead, AI Engineering

Tekcogent Solutions Pvt Ltd · Chennai · May 2026 to present
  • Lead the AI engineering team through Scrum sprints and Kanban boards, from requirements to production release.
  • Deliver LLM, RAG and multi-agent solutions with FastAPI microservices, CI/CD pipelines and cloud deployment.
  • Work directly with clients and vendors to scope work, report progress and keep both sides satisfied.
  • Review code, mentor engineers and set standards for testing, tracing and cost control.

Technical Mentor

Google Developers Group · Apr 2024 to Jan 2026
  • Mentored 15+ engineers on OOP, data structures and algorithms, and system design.
  • Resolved pipeline and data errors for junior data engineers in AWS and GCP big data environments.
  • Trained developers on Snowflake, BigQuery, data lake architecture, PySpark, Kafka, Airflow, Docker, Kubernetes, Cassandra, HBase and dbt.

Data Engineer

Google Developers Group · Nov 2022 to Mar 2024 · supported multiple clients
  • Designed a scalable GCP data lake for central storage and processing.
  • Built ETL/ELT pipelines into Snowflake and BigQuery that raised data availability and cut latency.
  • Automated batch and streaming workflows with Cloud Storage, Dataflow, Pub/Sub and Composer.
  • Added data quality checks and monitoring, which led to 40% fewer data quality issues.
  • Improved query performance by 30–35% with indexing and schema optimization, and lowered Snowflake and BigQuery cost through warehouse and slot management.

Junior Software Engineer
