Scalable Core Engine for Global Fintech API

3.5 Million+
Daily API Calls Handled
The Challenge

Their API failed under heavy traffic spikes during peak settlement hours.

Our Execution

We re-architected their transaction logs using Go microservices and Redis storage pipelines.

Measured Results
  • Eliminated server timeout errors entirely
  • Reduced database connection costs by 40%
  • Maintained sub-15ms response latency under peak load

Automated QA Infrastructure for SaaS Billing Platform

94% Less
Manual QA Execution Time
The Challenge

Monthly code releases took 4 days of manual QA sweeps, delaying features.

Our Execution

We designed a Playwright automation suite running concurrent E2E user tests on container splits.

Measured Results
  • QA sweeps completed in 14 minutes instead of 32 hours
  • Caught 100% of integration regressions before sandbox merges
  • Freed engineers to write features instead of manual checklists

Zero-Downtime Cloud Migration for Healthcare Portal

100% Uptime
During Large Scale Migration
The Challenge

Legacy patient servers were fragile, costly, and failed security audits.

Our Execution

We migrated data schemas to multi-region AWS EKS clusters with Terraform automation plans.

Measured Results
  • Satisfied strict HIPAA compliance benchmarks
  • Reduced cloud hosting costs by 28% through autoscaling
  • Enabled blue-green deploy models for zero-downtime upgrades

RAG Document Retrieval Platform for Logistics Firm

88% Faster
Document Lookup & Routing
The Challenge

Staff spent hours reviewing long shipping contracts and custom regulatory sheets manually.

Our Execution

We deployed a vector-based semantic search engine fine-tuned on custom shipping documents.

Measured Results
  • Reduced manual contract reading runs by hours
  • Maintained complete data safety within an isolated VPC
  • Integrated AI insights directly into customer support dashboards
Measured Outcomes

We translate complex code blocks into measurable business metrics.

Sun System Infotech works beyond basic feature delivery. We audit error logs, measure latency response curves under load, track database transaction expenditures, and verify compute scales.

Manual QA Sweeping Runs

Finance & Payment API

Designed Go and Rust event handlers processing 3M+ settlement calls daily with absolute database connection throttling checks.

Private AI VPCs

Deployed LangChain RAG vector databases querying logistics folders securely, keeping custom models locked within network wrappers.

Healthcare Cloud Sprints

Migrated fragile legacy database servers to AWS EKS using blue-green models, maintaining 100% service uptime during cutovers.

Distributed QA Sweeps

Integrated concurrent Playwright test blocks directly in pull requests, verifying code safety in 14 minutes.
