I Scale Systems to 1M+ Users.

Tanmay Shahane | Hands-on CTO & Principal Architect Building high-performance SaaS & FinTech systems. Focus on Cost Optimization (40%+) and Scale.

"I don't just manage teams; I design the distributed systems they build."


⚡ Current Focus: KyubiSweep

The problem: Standard secret scanners (TruffleHog/Gitleaks) are too heavy for quick local audits. My Solution: A Go-based, quarantined secret scanner for local filesystems.


🏗️ My Signature Architecture (SaaS/FinTech)

A high-level view of how I design for resiliency and cost-efficiency (based on my work handling 500K+ daily requests).

🛠️ The CTO Stack (My Technical Bets)

I don't list "skills." I list the tools I bet my infrastructure on.

Layer My Choice Why? (The "War Room" Logic)
Compute AWS Lambda + K8s Used this hybrid approach to cut infra costs by 42% ($180k/yr) at Famigo.
Backend Node.js & Go Node for rapid SaaS logic; Go for high-throughput microservices.
Database PostgreSQL Optimized queries by 73% (3.2s → 850ms) handling 50M+ records.
DevOps Terraform IaC is non-negotiable. Reduced deployment time from 2 hours → 12 mins.
Security Shift-Left Compliance (PCI-DSS/HIPAA) must be automated in the pipeline.

🔥 Engineering Highlights (Proof of Work)

1. The "Shark Tank" Scale (FinTech)

  • Context: Lead Architect for Bravo Tip or Pay (Featured on Shark Tank S9).
  • The Challenge: High-volume transaction processing with zero margin for error.
  • The Fix: Built a blockchain-based verification layer that reduced fraud by 89% and secured PCI-DSS compliance.

2. The Monolith Killer (SaaS)

  • Context: Migrating a legacy platform serving 1M+ users [Famigo].
  • The Challenge: System was brittle; API response times averaged 800ms.
  • The Fix: Strangled the monolith into Serverless Microservices.
  • Result: 99.94% Uptime and API latency dropped to 180ms.

3. The Live-Stream Surge (EdTech)

  • Context: Architecting a WebRTC infrastructure for UTTM.
  • The Challenge: Supporting 8K+ concurrent video streams.
  • The Fix: Implemented a custom CDN strategy.
  • Result: Reduced bandwidth costs by $15k/month and buffering by 81%.
