About BKJ Tech
A front-end engineering practice led by Bhavesh Kumar — Founder & Lead Engineer, Lead Member of Technical Staff at Salesforce.
BKJ Tech is how I bring enterprise-grade front-end engineering to clients who need more than a contractor — they need someone who has led migrations for 16K daily users, cut bundle sizes by 40%, and shipped features that closed $3M deals.
Whether you're a startup launching an MVP, a company modernizing a legacy app, or a team that needs a senior front-end lead — I work end-to-end: architecture, implementation, performance, and delivery.
My personal products — JSON Forge, Everyday Tools, and a Finance Dashboard — aren't side hobbies. They're proof that I can take an idea from zero to production, independently.
How We Work
Discover
Understand your goals, users, constraints, and success metrics. No cookie-cutter proposals.
Plan
Define scope, architecture, and milestones. Clear deliverables before a single line of code.
Build
Ship iteratively with regular demos. Performance and maintainability built in, not bolted on.
Deliver
Hand off production-ready code, documentation, and knowledge transfer so your team can own it.
Why Work With Us
Enterprise-proven, startup-speed
14 years at Salesforce, Gainsight, and Pega — but I ship personal products independently, so you get rigor without bureaucracy.
Outcomes, not hours
Every engagement is scoped around measurable results: faster load times, shipped features, migrated users — not timesheets.
Full ownership
Architecture, code, performance, deployment. One senior engineer who can own the front-end end-to-end.
