01 — MY APPROACH
Code should be as maintainable as it is performant.
I believe in building systems that handle growth gracefully. Over-engineering is a risk, but under-thinking the architecture is worse.
Scalability is a result of smart design decisions, not just more hardware.
I.
Performance is a feature.
Latency kills user trust. Whether it's caching strategies or query optimization, every millisecond saved improves the user experience.
II.
Decoupling enables agility.
Moving from monoliths to microservices isn't just a technical upgrade; it's a way to give teams the independence they need to ship faster.
III.
Documentation is architecture.
A system is only as good as the team's ability to maintain it. I prioritize clean code and clear documentation to ensure long-term stability.
02 — SELECTED WORK
FLYDOCS · CLOUD MODERNIZATION · 2025
Modernizing legacy aviation systems.
TECH STACK
NestJS, Kafka, Azure
THE CHALLENGE
Monolithic technical debt.
The platform was a 20-year-old legacy system. The goal was to decompose it into independent microservices without disrupting critical aviation SLA requirements.
We needed to ensure zero-downtime releases while migrating high-stakes maintenance data into a more resilient, cloud-native structure.
THE STRATEGY
Event-driven architecture.
We migrated synchronous service calls to Kafka event streams and implemented robust API caching to decouple dependencies.
By adopting a service-oriented mindset, we empowered individual teams to own their deployments, significantly increasing our shipping velocity.
THE WORK · DEVELOPMENT PHASES
PHASE 1
Analyze
Identified bottlenecks in the legacy codebase and mapped dependencies across 30+ modules.
PHASE 2
Decompose
Extracted core business logic into NestJS microservices with clearly defined bounded contexts.
PHASE 3
Optimize
Introduced Redis caching and event-driven communication to boost system throughput.
PHASE 4
Deploy
Orchestrated zero-downtime migrations within the Azure cloud environment.

TECH INSIGHT — ARCHITECTURAL CHOICES
Modernizing a legacy monolith.
Big Oh Tech · 2025
Tasked with decomposing a 20-year-old aviation records platform. The challenge wasn't just the code, but maintaining zero-downtime for 75+ airlines while shifting to a microservices architecture. It required careful planning to ensure service independence.
What I learned: A gradual, service-by-service migration beats a rewrite every time. It preserved system stability while allowing us to scale specific components independently using NestJS and Kafka.
TECH INSIGHT — PERFORMANCE TUNING
Optimizing API response times.
Big Oh Tech · 2025
Faced with latency issues across 30+ services, I implemented multi-layer Redis caching. I initially underestimated the complexity of cache invalidation, but refined the strategy until we achieved a 40% reduction in response times.
The result was a more responsive platform for aviation engineers. It reinforced that performance isn't just about faster queries, but about intelligent data fetching and caching at the right layer.
TECH INSIGHT — SAAS ARCHITECTURE
Building a multi-tenant website builder.
imyme Project · 2024
I built 'imyme' to learn the nuances of multi-tenant SaaS. Managing wildcard subdomains and dynamic TLS for users required a deep dive into Next.js middleware and clever infrastructure design.
By using a polyglot approach—PostgreSQL for structure and MongoDB for flexible content nodes—I avoided the typical scaling bottlenecks found in simple document-store architectures.
