The stack I reach for when speed, reliability, and product feedback matter.
Tools change, but the goal does not: choose boring foundations where possible, move fast where it matters, and instrument the product early enough to learn from real usage.
Product apps
Next.js, React, TypeScript, Tailwind CSS
My default stack for web apps, dashboards, marketing sites, and founder-facing products where SEO, speed, and maintainability all matter.
Flutter and Dart
Useful for shipping polished cross-platform mobile apps with one codebase, especially when the product needs subscriptions, onboarding, analytics, and release iteration on iOS and Android.
Remix, Prisma, and Stripe
A strong combination for SaaS products that need clear data models, durable forms, billing, subscriptions, and a practical path to production.
Back end and data
Node.js, Fastify, Express, GraphQL, REST
I use the simplest API shape that fits the product, from lean REST services to GraphQL systems where the domain benefits from richer query boundaries.
PostgreSQL, Supabase, MongoDB, Redis, Elasticsearch
Relational data for core product state, document stores when the data model demands it, Redis for queues/caching, and search infrastructure where discovery is a real product feature.
Python, Pandas, NumPy, scikit-learn, XGBoost, LightGBM
The stack behind PatternRank-style data pipelines, feature engineering, model experimentation, and repeatable backtesting.
Infrastructure
Vercel, AWS, Docker, Kubernetes, GitHub Actions
I pick deployment paths based on the product stage. Vercel is great for fast web delivery; AWS, containers, and CI/CD come in when the system needs more control.
Firebase, RevenueCat, Segment, Mixpanel
For mobile and early product loops, analytics, crash reporting, entitlement management, and funnel visibility are part of the build, not an afterthought.
