Senior Python Backend Engineer | FastAPI, PostgreSQL, AWS, LLMs

Hi, I'm Harsh, a senior Python backend and data engineer based in Bengaluru. I'm available for remote contract, part-time, or full-time work.

Over the past 5+ years, I've built backend systems, data platforms, and AI-powered products. Most recently, I took a year to build my own startup. It didn't work out, but I shipped real products, learned a lot, and I'm now looking to bring that experience to a team solving hard engineering problems.

Technical Expertise

Python: FastAPI, Django, Pydantic, SQLAlchemy, REST APIs
Databases: PostgreSQL, Redis, schema design, query optimisation
Data Engineering: ETL/ELT pipelines, data validation, Kafka/Airflow-style workflows
AWS: Lambda, S3, RDS, Glue, EMR, CloudFront, Docker, CI/CD
AI: LLM integrations, multi-provider orchestration, TTS pipelines
Backend Infrastructure: Payments, webhooks, JWT auth, RBAC, audit logging

Professional Highlights

5+ years in backend, data, and AI engineering
Led a team of 8 engineers at Perfios
Reduced lending turnaround from 15–20 days to under 2 days
Built ML models with 95% EMI prediction accuracy
Shipped production systems using FastAPI, PostgreSQL, Redis, AWS, and real-time architecture
AWS Certified Solutions Architect – Associate

Approach

I enjoy taking ownership of products end-to-end, from architecture and data modelling to deployment and production support. If your team needs someone who can work through ambiguous requirements, solve difficult backend problems, and ship production-ready systems with minimal hand-holding, I'd love to talk.

Compensation

$30–$50/hour depending on scope, or fixed-price projects.
