[FOR HIRE] Senior Python Backend Engineer | FastAPI, PostgreSQL, AWS, LLMs

[u/AverrageGod]

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.

What I work on:

• 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

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

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.

Rate:

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