Founder & Lead Architect
Vivek Mishra is the founder and lead architect at ERPStack. He designs and ships custom ERP systems and B2B platforms end to end — PostgreSQL schemas, Next.js application layers, and the SOC 2-ready delivery pipelines that carry them to production. Every architecture on this site is his work.
The architecture that carries you to 1,000 users is the one that fails at 100,000. Connection pooling, cache invalidation and tenancy under load.

Odoo, ERPNext and the rest are free to license and expensive to run. Where the money actually goes, and when open source is still the right call.
Descriptive title: Open Source ERP Alternatives: The Real Cost
RSC patterns that hold up at enterprise scale: data-fetch placement, the client boundary, and the caching mistakes that undo the gains.

I believe that corporate software infrastructure should be treated as a high-yield capital asset, not an operational expense. My engineering lifecycle is governed by three non-negotiable principles:
We enforce strict type-narrowing across transaction boundaries. No type assertions, casting, or raw 'any' types are permitted in production builds, guaranteeing that compile-time checks catch runtime discrepancies.
Applications are designed around React Server Components (RSC) to minimize client bundle overhead. Edge middleware intercepts routing paths to implement authentication checks under 5ms worldwide.
We model data using clean, indexed SQL entities under Drizzle ORM. Database segregation is handled via schema-level isolation policies to ensure data residency and simple scaling under connection pooling.
Who writes this blog, what he has built, and how an engagement starts.
Vivek Mishra is the founder and lead architect at ERPStack. He designs and ships custom ERP systems and B2B platforms end to end — PostgreSQL schemas, Next.js application layers, and the SOC 2-ready delivery pipelines that carry them to production. Every architecture on this site is his work. He writes and reviews every article on the ERPStack blog, and the reference architectures listed on this page are systems he designed and shipped rather than case studies bought in from elsewhere.
Vivek Mishra has published 20 long-form engineering articles on the ERPStack blog, filed across 5 clusters: architecture, compliance, erp, nextjs and performance. The subjects are custom ERP economics, Next.js at enterprise scale, multi-tenant isolation in PostgreSQL, edge and React Server Component performance, and HIPAA and GDPR obligations. The most recent, “The Architecture That Got You to 1k Users Will Kill You at 100k Users”, was published on June 3, 2026.
Three of Vivek Mishra's reference architectures are documented in full on this site: Real-Time Fraud Detection Platform (Cybersecurity / FinTech — sub-0.1% false-positive risk scoring), Field Operations & Compliance Portal (Non-profit / NGO — 70+ collections, 12 modules) and Public-Health Data Dashboard (Government / Healthcare — React + AWS deployment). Each has its own case study with the architecture, the constraints it was built under and the outcome.
Vivek Mishra has published 20 articles totalling 42,782 words — roughly 204 minutes of reading — between May 1, 2026 and June 3, 2026. Every article page shows both the date it was published and the date it was last reviewed, and the review date is a real timestamp rather than an automatic refresh. Nothing on the blog is ghostwritten or syndicated.
Every article Vivek Mishra publishes is served as plain markdown alongside the HTML: this author page at erpstack.io/blog/author/vivek-mishra.md, the index at erpstack.io/blog.md, each cluster at erpstack.io/blog/category/<slug>.md and each article at erpstack.io/blog/<slug>.md. Each markdown file carries the same text as the HTML page, a canonical link back to it, and the publication and review dates in its front matter.
Vivek Mishra runs a free architecture audit: a short assessment at erpstack.io/tools/architecture-audit-grader that scores an existing system against modern architecture benchmarks. From there, erpstack.io/contact opens a direct conversation about scope and delivery. ERPStack works remotely with no per-seat licence fees, and every engagement leaves the client owning the source code outright.
