About Me

Last updated on Oct 23, 2026

I’m Prateek Mishra, a frontend-focused software engineer with 9+ years of experience turning messy, real-world requirements into UIs and platforms that hold up in production. My home base is Angular — migrations, performance, tooling, developer experience — and most of that career has been staff-level ownership of frontend platforms rather than single features. Outside of work, this site is where I write about engineering, lifestyle, books, and philosophy.

What I work on now

I’m a Staff Engineer at a fintech SaaS company — the latest step in a 9+ year run across startups, agencies, and enterprise product teams. I own platform modernization for a production Angular application and its shared libraries. Day to day that means major-version upgrades, build-tooling and CI performance, and developer-experience work for the team around me. I also design and run the event-instrumentation pipelines that the analytics org depends on — getting product usage data flowing reliably at real scale, not just in a demo.

Selected achievements

• Led a five-major-version Angular + PrimeNG migration (v16 → v21, TypeScript 4.9 → 5.9) across a production application and two shared libraries — ~70% faster CI builds (~180 runner-hours saved monthly), 79% fewer dependency vulnerabilities, zero production incidents.
• Designed and shipped an event-instrumentation pipeline (ClickHouse-backed) now capturing ~1M interactions/day (~12/sec) across ~95K records, ~5,000 customers, and ~700 accounts tracked daily — first working version delivered to staging in 4 days.
• Drove core parts of a ~39,000-user phased rollout: owned cohort segmentation (lowest-value accounts first, to contain blast radius) and built the adoption dashboard tracking deflections, round-trippers, and throughput.
• Cut production error volume ~91% (295K → ~25K) in one week by owning triage end-to-end, contributing to a project-wide drop from 372K to 161K.
• Closed a known XSS / arbitrary-script-execution vulnerability in PDF rendering by upgrading pdf.js v3 → v4.
• Authored a frontend linting and formatting technical direction doc — an ESLint 9 flat-config migration with hook-based enforcement, grandfathering ~5,655 existing findings so the gate could go live without a code freeze.
• Cut CI build times 30% and hit sub-30-second local serve times by moving a separate codebase off Webpack onto Vite/esbuild, alongside a full Angular v11 → v20 migration and 92% reduction in dependency vulnerabilities.
• Architected an Nx monorepo spanning 50+ shared libraries across 4 Angular applications, cutting code duplication ~30%.
• Replaced a managed real-time infrastructure stack with a custom Socket.IO/Node/MongoDB/Redis build in 7 days, cutting monthly infrastructure cost 45%.
• Migrated a global bank’s mobile app from KnockoutJS/jQuery Mobile to Angular 5 + Ionic 3 in 4.5 months, and cut CI build times 40% along the way.

How I work

• I default to platform thinking: fixing the underlying tooling or architecture problem rather than patching around it, even under deadline pressure.
• I treat instrumentation as part of delivery, not an afterthought — if I can’t measure the impact of a change, I haven’t finished shipping it.
• I make deliberate trade-off calls when business urgency and platform work compete, and I own the second-order cost of deferring the latter.

Writing

On the blog I write about frontend engineering, debugging production issues, build-tooling trade-offs, and framework migrations — mostly things I had to work out the hard way and wished someone had written down first. You can browse all of it on the blog.
