Detailed Technical Case Studies
LearnStack
White-Label Cloud Learning Management System
Organizations required a dedicated white-label learning platform featuring course authoring, timed quizzes, student certification, interactive sessions, and tenant administration. The challenge was building an architecture supporting isolated multi-tenant routing and high database availability without crippling operational overhead.
Architected and deployed a multi-tenant cloud platform using React, TypeScript, Fastify, and PostgreSQL with Prisma. Packaged services into optimized Docker containers running on AWS ECS Fargate across multiple availability zones. Provisioned Amazon RDS PostgreSQL Multi-AZ replication, Route 53 routing, and modular Terraform infrastructure-as-code with automated GitHub Actions CI/CD workflows.
Measurable Business Results
- •Built and deployed a resilient multi-tenant platform with sub-second response times across all tenant domains
- •Zero-downtime rolling container updates achieved via automated ECS task health drain cycles
- •High-availability database tier with automated multi-AZ failover and continuous automated snapshots
- •100% reproducible Infrastructure as Code managed through version-controlled Terraform modules
RateStack
High-Throughput Freelance Contract Engine
An automated freelance contract indexing and market rate valuation platform needed to parse, evaluate, and index fluctuating developer market rates in near real-time. With seed funding constraints, the engineering team had a strict requirement: keep production infrastructure costs strictly under $1.00/day while remaining resilient to viral spikes.
Architected a radical serverless micro-architecture utilizing AWS Lambda (ARM64 Graviton2) triggered by API Gateway, backed by Amazon DynamoDB with on-demand capacity and S3 static web delivery through CloudFront edge nodes. Established fine-grained CloudWatch billing alarms, payload compression, and edge caching to eliminate idle compute overhead entirely.
Measurable Business Results
- •Delivered a rock-solid production environment at exactly $0.64/day average cloud expenditure
- •Sub-180ms global API response time achieved through edge caching and Graviton execution
- •Over 85,000 contract calculations processed with zero server maintenance overhead
- •Autonomous scaling from 0 to 10,000 concurrent requests without manual intervention
FitLyfe
Real-Time Mobile Calorie & Health Tracker
A fast-growing mobile nutrition and biometric tracking application built with Flutter was experiencing severe database connection spikes and synchronization bottlenecks during breakfast and dinner peak hours. Meal photo uploads clogged API threads, causing timeout errors and frustrated app store reviews.
De-coupled the heavy image analysis and calorie intake pipeline using an asynchronous event-driven architecture on AWS. Client uploads stream directly to signed S3 buckets, firing SQS message queues consumed by ECS worker tasks. Integrated AWS RDS Proxy to manage pooled PostgreSQL connections seamlessly alongside a high-speed Redis caching tier for instant nutritional item lookups.
Measurable Business Results
- •78% reduction in image upload ingestion latency and meal logging latency
- •Zero connection dropouts or RDS exhaustion under 12,000+ concurrent active mobile users
- •Automated multi-platform CI/CD pipeline building, testing, and distributing Flutter builds
- •99.95% API service availability sustained across international mealtime peak surges
Battle-Tested Cloud Engineering
From ultra-lean serverless microservices executing at sub-dollar daily budgets to high-throughput mobile ingestion pipelines with asynchronous SQS queues and RDS connection pooling, every system is built for zero downtime and ruthless cost efficiency.
• AWS ECS (Fargate) & Graviton ARM64
• Terraform Modular Infrastructure as Code
• Amazon RDS & Connection Pooling Proxy
• Amazon CloudFront CDN & Route 53
• Redis Caching & In-Memory Acceleration
• GitHub Actions Automated CI/CD
