Fintech Core API Penetration Testing & Token Hardening

Full-scope authorized penetration test and API architecture hardening for a multi-tenant payment settlement gateway processing ₹45M+ daily volume.

The Operational Challenge

Prior to enterprise SOC 2 audit, the client required an exhaustive white-box and gray-box assessment of their transaction processing API. The challenge was identifying latent business logic vulnerabilities, race conditions in ledger updates, and token hijacking vectors without causing payment stream latency.

The Architectural Solution

RubaCore Labs executed a rigorous 14-day security engagement. We identified 3 critical authorization flaws (BOLA/IDOR in payout webhook endpoints) and simulated microsecond race conditions. We supplied exact cryptographic patch routines, implemented strict JWT replay protection with Redis bloom filters, and hardened IAM boundaries.

B2B SaaS Organic Search Engine Architecture & Core Web Vitals

Comprehensive technical SEO overhaul, Next.js server-side rendering restructuring, and programmatic topical authority silos resulting in a 340% organic lead surge.

The Operational Challenge

The client's single-page application suffered from client-side hydration delays and severe crawl budget waste. Googlebot was failing to index 60% of their product landing pages, and Core Web Vitals scores hovered in the red zone (LCP > 4.8s).

The Architectural Solution

We rebuilt the public discovery architecture with Next.js App Router, streaming SSR, and edge caching. We generated structured JSON-LD entity graphs for all logistics domain terms, mapped 180+ high-intent commercial keywords, and engineered automated sitemap partitioning.

Autonomous Multi-Agent Document Processing & Verification Pipeline

Engineering a high-accuracy, zero-hallucination document extraction and policy validation system cutting manual claim review time by 82%.

The Operational Challenge

Claims adjusters were manually parsing 40+ page policy declarations, hospital receipts, and police FIRs, averaging 48 minutes per file with high human fatigue error rates.

The Architectural Solution

RubaCore Labs deployed a secure multi-agent workflow powered by Gemini 2.5 and specialized extraction agents. The system checks document integrity, extracts tabular line items into structured JSON, cross-references policy coverage exclusions, and flags suspicious discrepancies for human oversight.
