Systems that hold up under real traffic.

01. About

I build backend systems that stay fast and correct at scale.

I'm a backend software engineer based in Mumbai, India. I build and ship production systems across the Python ecosystem, from high concurrency AsyncIO pipelines to FastAPI microservices and AI/LLM integrations.

At Homeville Group I work on AI microservices, LLM integration, and Python ecosystem projects under the VP of Technology. I have rebuilt loan processing pipelines, shipped Tier-1 bank integrations, and modernized OCR and reconciliation systems.

My work was recognized at the Global Fintech Festival 2025. I care about systems that stay fast and correct under real traffic, enterprise constraints, and messy data.

Software Engineer

Homeville Group

AI microservices, LLM integration, and Python ecosystem projects under the VP of Technology

  • Rebuilt a loan processing pipeline that crashed past 300 concurrent loans into one stably handling 6,000+ with AsyncIO.
  • Cut batch runtime 95% from over 30 minutes to under 2 minutes across around 800K rows per run.
  • Eliminated a MySQL query bottleneck, cutting query latency from 80 seconds to 7 seconds at high concurrency.
  • Spearheaded the end to end build of a FastAPI speech to text and translation service with Gemini API summaries.
  • Benchmarked open source and cloud transcription models and selected Fast Whisper for production.
  • Evaluated multi-cloud storage and compute economics across AWS S3 and GCP GCS for cross-cloud egress and migration.
  • Built and shipped 2 Tier-1 bank integrations end to end with idempotent data contracts for critical transactions.
  • Developed CRON driven async workers for event driven automation, anomaly detection, and reporting.
  • Automated conversion of production data into masked dummy datasets, replacing manual test data creation.
  • Built post-deployment validation scripts comparing old and new outputs, saving a day of manual cross-checks per release.
  • Migrated the multi-tenant reconciliation engine to Python, aligning it with the core backend stack.
  • Modernized the OCR pipeline with upgraded text extraction, image transformation, and PII masking for image and PDF.
