Selected Work
Real systems we've built, modernized, or scaled. Focused on architecture, performance, and long-term maintainability.
Legacy Monolith to Microservices
The Problem
A 10-year-old PHP monolith was causing 4h+ downtimes during peak transaction windows. Deployment cycles took 2 weeks due to regression testing fears.
What We Built
We implemented a Strangler Fig migration, peeling off high-volume endpoints to Node.js lambdas while keeping the core ledger operational.
Technical Highlights
- >> Zero downtime during data migration
- >> Implemented circuit breakers for failure isolation
- >> Automated contract testing between services
Outcome
Transaction throughput increased 300%. Deployment frequency went from bi-weekly to daily.
Multi-Tenant SaaS Portal
The Problem
Existing client portal was slow and insecure. Client needed to serve 500+ clinics with strict data isolation and HIPAA compliance requirements.
What We Built
Built a Next.js App Router platform with Row Level Security (RLS) in Postgres. Implemented a custom RBAC system for granular permissions.
Technical Highlights
- >> Sub-second page loads via React Server Components
- >> Strict multi-tenant logical isolation
- >> Real-time notifications for patient updates
Outcome
Onboarded 50 new clinics in Month 1. SOC2 audit passed with zero critical findings.
AI Legal Document Analysis
The Problem
Paralegals were spending 20h/week manually tagging scanned PDFs. Off-the-shelf AI wrappers were hallucinating critical dates.
What We Built
Engineered a RAG (Retrieval Augmented Generation) pipeline using disjoint chunking and vector search to ground LLM responses in fact.
Technical Highlights
- >> Custom PDF parsing pipeline for OCR accuracy
- >> Citation layer: AI points to exact source page
- >> Human-in-the-loop review interface
Outcome
Reduced manual review time by 80%. Accuracy improved to 99.5% with human verification.
