Case Studies

Things we've helped build.

Real problem formulations, architectural trade-offs, and practical software systems built for durability and everyday use.

Backend & SystemsCase Study 01

Real-Time Transaction Reconciliation Engine

A high-volume transactional platform was experiencing payment discrepancies across multiple gateways. Midnight batch audits were failing due to database lock contention, forcing the team to spend hours on manual spreadsheet checks.

What Needed Solving:

Eliminating payment mismatches, preventing database contention during traffic spikes, and automating reconciliation as transactions happen in real-time.

What We Built:

An asynchronous financial ledger and reconciliation service in Go and PostgreSQL that verifies settlements continuously and triggers instant alerts if an unmapped transaction occurs.

Unified Supply Chain Operations Portal

Logistics coordinators were managing purchase orders across four separate legacy ERP tools and dozens of emailed spreadsheets. Orders were frequently delayed by up to 5 business days due to manual copy-paste errors.

What Needed Solving:

Consolidating four fragmented legacy systems into a single intuitive dashboard, automating purchase order approvals, and providing real-time status tracking for warehouse teams.

What We Built:

A responsive, role-based operational command center built with TypeScript, Next.js, and PostgreSQL that unifies order status and synchronizes updates automatically.

SaaS & Cloud ArchitectureCase Study 03

Multi-Tenant B2B SaaS Architecture & Billing Engine

A growing B2B analytics platform was suffering from slow database queries and noisy-neighbor issues as enterprise customer signups increased. Onboarding a new customer required 4 hours of manual engineer setup.

What Needed Solving:

Enforcing strict database-level customer isolation, speeding up query response times, and automating self-serve subscription billing.

What We Built:

A modernized multi-tenant SaaS foundation with automated onboarding, self-serve subscription management, and rock-solid tenant isolation.
