Executive Summary

What happened, why it mattered, what changed

Project Overview

Volt Banking isn't a traditional bank. They don't have branches. They don't have physical touchpoints. Their website IS the bank. Every millisecond of delay means lost trust, lost users, and lost revenue. In a fintech ecosystem where competitors are obsessing over speed, Volt was operating with a system that couldn't keep up with user expectations.

The Problem Volt Banking Needed Solved

Root cause, not just symptoms

Volt's legacy monolithic architecture was causing sub-optimal performance, with 4s+ mobile load times and a 35% bounce rate that directly impacted trust and revenue.

On the surface, everything looked functional. Underneath, it was bleeding performance — 4+ second mobile load times, bloated JavaScript bundles, and fragmented backend queries. Users were dropping off before the product even had a chance to convince them, producing a ~35% bounce rate at the entry point.

Strategy & Approach

How we designed the solution

Engineering Approach

We decoupled the frontend and backend, serving content from global edge nodes to reduce latency across all regions and eliminated unnecessary client-side JS for faster first paint and interaction. A full bundle audit cut initial payload by 68%.

Why This Works

This wasn't a redesign. This was a revenue infrastructure upgrade disguised as a website rebuild. Speed = Trust = Conversion. Every 100ms of improvement in load time maps directly to measurable uplift in signup completion.

How We Built It — Phase by Phase

Transparent execution, no black box

01

Deep Performance Audit

Mapped every bottleneck across network, rendering, and data flow. Identified the 20% of issues causing 80% of latency.

02

System Architecture Design

Designed a scalable headless structure optimised for edge delivery, decoupling content from rendering entirely.

03

Component Engineering

Built an atomic UI system with zero layout shift (CLS = 0) and 100% accessible, performance-first components.

04

Global Edge Deployment

Rolled out across Vercel's global edge network. Per-region latency tested and tuned before go-live.

The Critical Decision Point

Where most teams get stuck — here's what we chose

"Do we optimise the existing system — or rebuild for the future?"

Option A — Patch the existing CMS

Faster to implement, but limited upside. Structural bottlenecks remain. Only a temporary fix.

Option B — Re-architect the entire systemChosen

Long-term scalability, true performance gains, and a foundation that can support 10x growth.

We rebuilt from the ground up because incremental improvement couldn't solve a structural problem. The rebuild paid for itself in 6 weeks of improved conversions.

The Transformation: Before & After

The exact state change we engineered

Before WebMarv

Legacy monolithic CMS with 4s+ load times, 35% bounce rate, and a user journey that bled signups at every step.

After WebMarv

Headless edge architecture with 0.4s TTI, 7% bounce rate, and a performance-first foundation built for scale.

What We Learned Building This

Hard-won insights from the project

  • In fintech, speed = trust = conversion — performance is a product feature

  • Performance improvements consistently outperform visual redesigns in test results

  • Over-optimising too early slows down execution; audit first, then act

  • Edge systems require per-region tuning — a single global config underperforms

What the Client Said

"WebMarv didn't just improve performance — they changed how our platform converts. The 45% uplift in signups directly impacted our quarterly revenue targets. Best technical investment we've made."
