Hey, I'm Sahil

I’m a senior software engineer with 7+ years of experience architecting high-scale fintech platforms and payout infrastructure. I’ve built and scaled systems handling $80M+ in transaction volume, and I specialize in the messy, high-stakes parts of moving money: complex payment workflows, billing, ledgers, and compliance.

I work remote-first and comfortably overlap with NA/EU timezones. Alongside engineering, I’m a security researcher who brings an offensive-security mindset to the financial systems I build.

What I do

  • Fintech & billing infrastructure — spend management, card issuance, tiered/bucket billing, ACH pull, and accounting integrations.
  • Scale & reliability — payout and compliance systems for some of the largest GPs in the world, built on Kubernetes and tuned for throughput.
  • Security research — offensive security (OSCP path) applied to payment and payout flows.

Experience

  • Juniper Square — Software Engineer (Aug 2025 – Present, Bangalore). Architected a continuous AML compliance system for one of the largest GPs on the planet, deployed and optimized Kubernetes infrastructure, and built a no-code AI-powered platform for fund admins.
  • Klanto — Senior Software Engineer (Jan 2021 – Aug 2025, Remote). Architected a spend-management platform processing $80M+ GMV across 100K+ virtual and physical corporate cards, with tiered billing, automatic ACH pull, Mastercard card issuance, and ML-powered OCR/NLP receipt matching.
  • Exiver Labs — Software Engineer (May 2019 – Dec 2020, Remote). Led a team of 6 to deliver a full-featured LMS with integrated payments and enrollment, and modernized legacy Django infrastructure with zero downtime.

Skills

  • Languages: Python (type hinting, asyncio), JavaScript/TypeScript, SQL
  • Frameworks: FastAPI, Django, Flask, React, Next.js
  • Infrastructure/DevOps: Docker, Terraform, Kafka, Redis, GCP (Cloud Run, Pub/Sub), AWS, GitHub Actions
  • Databases: PostgreSQL, MySQL, Redis, BigQuery
  • Specialized: Payment gateways, ledger systems, gRPC, GraphQL, LLM orchestration (LangGraph, RAG), NLP

Security & recognition

Recognized by Paytm, Razorpay, and Shopify for identifying critical security vulnerabilities. I’m deeply interested in offensive security and apply it directly to financial system integrity.
