Backend & Applied AI Engineer focused on building scalable, observable, production-ready systems.
I work at the intersection of:
- Cloud-native backend engineering
- Data platforms & distributed systems
- LLM-powered applications (RAG, NL - SQL, agents)
- Cost-aware and reliability-first architectures
I care about systems that survive production - not just demos.
- Designing and building cloud-native distributed backend services
- Developing production systems using Node.js, Python, AWS
- Built ingestion pipelines with PII masking, validation, transformation layers
- Worked on CI/CD automation, observability, and production debugging
- Exploring real-world GenAI integration inside enterprise workflows
Actively contributing to core ecosystem tools:
- Contributions to dbt-core (data transformation engine)
- Contributions to LlamaIndex (LLM orchestration framework)
I enjoy working with maintainers, understanding architecture tradeoffs, and improving core systems.
- Production-ready RAG architectures
- Retrieval evaluation & cost optimization
- NL - SQL systems with validation layers
- Observability-first backend design
- Data pipelines using Airflow + dbt + Kafka
- AI-assisted developer tooling
- Build systems, not scripts
- Design for retries, failure, and scale
- Observability is not optional
- AI should reduce operational complexity
- Measure latency, cost, and reliability
- Node.js, Express.js
- Python (FastAPI, Flask)
- REST APIs, Microservices, Webhooks
- AWS (Lambda, S3, EC2, API Gateway)
- Docker & Serverless Architectures
- PostgreSQL, MongoDB, Redis, Supabase
- Apache Airflow, Kafka
- dbt (Postgres) - ELT pipelines
- Retrieval-Augmented Generation (RAG)
- LangChain, LlamaIndex
- Natural Language - SQL systems
- LLM-backed APIs & model serving
- Linux, Shell scripting
- CI/CD with GitHub Actions
- Git & GitHub workflows
- Production debugging & monitoring
- System design (Excalidraw)
- Jira, Confluence
I practice data structures & algorithms to strengthen system design fundamentals.
