Engineering & product playbooks
Hands-on playbooks, decision frameworks, and case studies from the team building AI-native products at CodeNicely.
How to Hire a Software Development Partner in India
Most Indian software vendors can ship a demo. Far fewer can ship a system that survives UPI reconciliation, GST return cycles, and Diwali traffic. Here's how to tell them apart before you sign.
Top AI Development Companies in India for U.S. Businesses
A practical guide for US COOs and VPs of Engineering shortlisting Indian AI development partners. Which vendor category fits which problem, and how to filter for teams that stay accountable after launch.
Migrate a Legacy ERP to the Cloud Without Freezing Operations
Most ERP cutovers don't fail on data quality — they fail in the final 72 hours, when no one designed a way to reconcile transactions written to the old system after the freeze. Here's the sequenced playbook to avoid that.
Celery vs. BullMQ vs. Temporal: Pick the Right Job Queue
Most job queue comparisons benchmark throughput and language support. The dimension that actually decides your architecture is whether your failure mode is a lost task or a corrupted workflow — and Celery, BullMQ, and Temporal each solve only one of those.
Build vs. Buy Your AI Scoring Model: A Decision Framework
Most build-vs-buy comparisons for AI scoring models are written by vendors and framed around cost and speed. Here is the axis that actually matters three years in — and how to score your own situation against it.
Your AI Model Didn't Fail. Your Feedback Loop Did.
Most post-launch AI accuracy drops get blamed on the model. They shouldn't be. The real culprit is almost always a feedback loop that was never wired up — and no amount of retraining will fix that.
Event Sourcing Is Not an Audit Log (And Mixing Them Breaks Both)
Event sourcing and audit logs both store change history, but they solve opposite problems. Retrofit one onto the other and you'll end up with an event store regulators can't query and an audit log holding up your write path.
Idempotent Webhook Consumers: A Step-by-Step Guide
Your Stripe webhook handler works — until a retry storm double-charges a customer. Here's a runnable Postgres tutorial for building a truly idempotent consumer, including the race condition most teams only find in production.
Multi-Tenant Data Isolation: The Pattern Cheatsheet
A dense reference for CTOs mapping their multi-tenancy model against enterprise security requirements. Which patterns prevent tenant data leakage, which merely obscure it, and what each costs you when you try to migrate later.
5 Mistakes Teams Make When Automating KYC Onboarding
Most KYC automation failures aren't loud rejections — they're silent passes and exception queues bigger than the manual process you replaced. Here are the five mistakes we keep seeing in production and how to recover from each.
How to Hire an AI Development Company in India
Most Indian AI proposals describe model fine-tuning and API wrappers, not the harder work of running a model inside a live business operation. Here's how to tell the difference before you sign.
Temporal Tables vs. Audit Logs: Pick One Before It's Too Late
Audit logs tell you who changed what. Temporal tables tell you what the row actually looked like at 3:47 PM last Tuesday. Confusing the two is a schema migration you don't want to discover during a compliance audit.
