How I build reliable, measurable products
A deeper look at the stacks, practices, and outcomes I focus on when delivering backend-heavy products with measurable reliability and performance.
Backend & Architecture
Designing resilient services with clean boundaries, observability, and predictable failure modes so releases stay boring.
What I focus on
- •Event-driven microservices with idempotent consumers, DLQs, and replay pipelines
- •AuthZ/AuthN with JWT/OAuth2, multi-tenant RBAC, and audit logging
- •REST APIs with OpenAPI/Swagger, pagination/versioning strategies, and circuit breakers
Node.js
NestJS
PHP
Laravel
Yii2
Redis
RabbitMQ
Data & Messaging
Keeping reads fast and writes safe with sane indexing, caching layers, and careful migrations that never wake up on-call.
What I focus on
- •MySQL/PostgreSQL schema design, indexing, partitioning, and query tuning
- •Caching tiers with Redis (TTL, locks, bloom filters) and cache-invalidation playbooks
- •Async work queues with retries, exponential backoff, and dead-letter routing

Frontend & UX
Shipping focused UIs that stay performant, accessible, and measurable so experiments run cleanly and quickly.
What I focus on
- •App Router with server components, mutations via server actions, and streaming
- •Core Web Vitals, bundle budgets, and image optimization strategies
- •A/B testing hooks, feature flags, and analytics instrumentation

TypeScript

Reliability & DevOps
Building guardrails so teams can ship faster: instrumentation, SLOs, and repeatable delivery pipelines.
What I focus on
- •SLI/SLO dashboards, alert policies, and playbooks for common failure modes
- •Dockerized services with multi-stage builds and minimal base images
- •CI/CD pipelines with lint/test gates, preview deployments, and migration checks

GitHub Actions
Vercel
AWS (EC2/S3/RDS)
DigitalOcean
Collaboration & Process
Keeping teams aligned through specs, API contracts, and review discipline so delivery stays predictable.
What I focus on
- •Technical design docs with trade-off analysis and rollout plans
- •API schemas first (OpenAPI), contract tests, and backward-compatible rollouts
- •Code review patterns that balance safety with velocity

Performance Wins
Concrete improvements delivered in production systems across latency, throughput, and conversion metrics.
What I focus on
- •Cut P95 latency ~30% via MySQL indexing, connection pooling, and Redis caching
- •Improved SLA from 84% to 96% by hardening state machines and retries
- •Raised conversion +9% and reduced drop-offs −22% with Next.js flow optimizations
