How I architect architect systems
Requirements Analysis
Understand scale targets, data relationships, consistency requirements, and performance SLAs.
Architecture Blueprint
Design service boundaries, data flow diagrams, API contracts, and infrastructure topology.
Data Modeling
Schema design with proper indexing, normalization decisions, caching strategy, and migration planning.
Implementation Guidance
Define coding patterns, module boundaries, error handling strategies, and testing approaches.
Deployment Strategy
Zero-downtime deployment pipelines, monitoring, alerting, and capacity planning.
Featured Work
Production projects as a Architect engineer
DispatchLink
B2B Freight Marketplace Connecting Carriers & Dispatchers
Problem
Freight dispatching is plagued by manual phone calls, untracked load confirmations, fragmented broker commissions, and slow escrow reconciliation.
Solution
Architected a unified real-time portal where carriers claim loads with automated geospatial radius search, live driver telemetry, and automated multi-tenant wallet payouts.
Architecture
- Next.js 15 App Router with Server Components for low-latency freight searches
- MongoDB 2dsphere indexes for polygon and radius origin-to-destination matching
- MapLibre vector maps rendering live driver routes and telemetry coordinates
- LemonSqueezy merchant-of-record integration for multi-party escrow billing
Verified Results
SchedMate
Enterprise Workforce Management & Shift Dispatching Platform
Problem
Enterprise facilities with hundreds of nurses and field contractors faced scheduling collisions, missed shifts, and manual attendance calculation across distributed branches.
Solution
Engineered decoupled NestJS microservices backed by Kafka event streams, Redis BullMQ background workers, and strictly typed PostgreSQL schemas.
Architecture
- NestJS modular microservices architecture partitioned by domain context
- Kafka distributed event streaming to synchronize shift allocations in real time
- Redis BullMQ worker queues handling scheduled shift notifications and reminders
- PostgreSQL + Prisma ORM with transactional safety and row-level audit trails

FAQ
Frequently asked questions
Do you build the system or just design it?
Both. I've architected and shipped production systems like SchedMate (enterprise microservices with Kafka) and DispatchLink (B2B marketplace with geospatial search). I design AND build.
What scale have your systems handled?
100k+ monthly background jobs with sub-85ms p95 API response times, 1,048+ matched freight dispatches, and 24/7 uptime for enterprise customer-facing systems.
Can you audit an existing architecture?
Yes. I review database schemas, API designs, deployment pipelines, and infrastructure topology — then provide actionable recommendations for performance, scalability, and reliability.
How do you approach distributed systems?
Event-driven architecture with Kafka for cross-service communication, BullMQ for async job processing, Redis for caching/rate-limiting, and strict service boundaries with clear API contracts.
Need a system designed for scale?
From database architecture to deployment strategy — I design systems that scale gracefully under real production load.
