We diagnose and fix the real causes of slow pages and sluggish apps—render-blocking assets, bloated bundles, weak caching, and unmonitored regressions—so speed gains hold up under real traffic, not just lab tests.

About Our Performance Practice
A Diagnostics-First Speed Engineering Partner
Not a plugin-and-pray shop.
ShubhDigi treats performance as an engineering discipline: we measure with real user data, trace slowness to its root cause, and fix the architecture behind it—not just swap a few settings and call it done.
We work across the full stack that determines speed—server response times, rendering paths, JavaScript execution, image pipelines, and CDN configuration—because Core Web Vitals rarely improve from a single lever.
Every engagement leaves you with performance budgets, CI gates, and monitoring dashboards so the gains survive the next feature release instead of decaying within a quarter.
Measure before you fix
Real user monitoring and field data guide priorities—lab scores alone can mislead.
Fix causes, not symptoms
Render-blocking code, oversized payloads, and slow backends get addressed at the source.
Budget the wins
Performance budgets and CI gates stop future PRs from quietly reversing progress.
Tie speed to outcomes
Conversion, ranking, and retention impact are tracked alongside the raw metrics.

Plugin-only fixes
Cache plugins and CDN toggles applied without understanding what is actually slow.
Diagnostics-first engineering
Root-cause analysis, targeted fixes, budgets, and monitoring that hold the gains.
Performance delivery cycle
Audit → prioritize → fix → budget → monitor → iterate
Performance Friction Points
Speed decays when
no one owns the budget.
Most sites launch fast and slow down gradually as features, scripts, and images pile up unchecked.
Janky interactions (poor INP)
Heavy JavaScript blocks the main thread, making taps and clicks feel delayed and unresponsive.
Unoptimized images & fonts
Oversized images and blocking web fonts silently inflate load time on every page.
No performance budget or CI gate
Without automated checks, each release can quietly add weight until speed collapses.
Bloated JavaScript bundles
Unused code, duplicate dependencies, and no code-splitting ship megabytes users never touch.
Weak caching & CDN setup
Misconfigured cache headers and missing edge delivery force repeat work on every request.
Performance Service Menu
Capabilities that take metrics
from red to consistently green.
Full-stack speed engineering—diagnostics, fixes, budgets, and monitoring—scoped to what is actually slowing you down.
Core Web Vitals Audits & Fixes
Field and lab diagnostics for LCP, INP, and CLS, followed by targeted engineering fixes.
Image & Asset Optimization
Modern formats, responsive sizing, lazy-loading, and compression pipelines that cut payload weight.
JavaScript Bundle Optimization
Code-splitting, tree-shaking, and dependency audits that shrink what ships to the browser.
Caching & CDN Strategy
Cache headers, edge delivery, and invalidation strategies tuned to your content and traffic patterns.
Server Response (TTFB) Tuning
Backend query, rendering, and infrastructure fixes that cut time-to-first-byte across key routes.
Font & Rendering Optimization
Font-display strategies, critical CSS, and render-path fixes that eliminate blocking delays.
Performance Budgets & CI Gates
Automated size and metric thresholds wired into your pipeline so regressions get caught pre-merge.
RUM & Synthetic Monitoring
Real user monitoring and scheduled synthetic checks that surface regressions before customers complain.
Performance Tracks
Speed programs matched
to how your platform is built.
Different platforms fail differently—select the track that matches your stack and traffic profile.

How We Optimize Performance
A path from sluggish pages to
measured, monitored speed.
Eight steps with clear durations—diagnose first, fix at the source, then protect the gains with budgets.
STEP 01
Performance Audit & RUM Baseline
Field data, Lighthouse traces, and waterfall analysis establish where time is actually being lost.
STEP 02
Prioritized Fix Roadmap
Issues ranked by user impact and effort so the biggest wins ship first, not the easiest ones.
STEP 03
Asset & Bundle Optimization
Images, fonts, and JavaScript bundles get resized, split, and trimmed at the source.
STEP 04
Rendering & Caching Fixes
Critical CSS, render-blocking removal, and cache header corrections speed up first paint.
STEP 05
Backend & TTFB Tuning
Query optimization, server-side caching, and infra adjustments reduce time-to-first-byte.
STEP 06
Regression Testing
Cross-device and cross-network verification confirms fixes hold under real conditions.
STEP 07
Budget & CI Gate Setup
Size and metric thresholds are wired into CI so future releases cannot silently regress.
STEP 08
Continuous Monitoring & Iteration
RUM dashboards and scheduled audits keep speed visible as traffic and features evolve.

Performance Capabilities
What durable speed
requires under the hood.
Twelve capabilities that keep Core Web Vitals green as content, features, and traffic grow.
01Core Web Vitals
LCP optimization
Hero rendering paths, preloading, and server timing tuned to hit the 2.5s target reliably.
02Core Web Vitals
INP & interaction responsiveness
Main-thread work is broken up so taps, clicks, and inputs feel instant under real usage.
03Core Web Vitals
CLS stability
Reserved space for media and dynamic content stops layout from jumping mid-load.
04Assets
Image format & lazy-loading pipelines
Modern formats, responsive srcsets, and lazy-loading rules cut payload without hurting UX.
05Rendering
Critical CSS & render-blocking fixes
Above-the-fold styles inline early while non-critical CSS defers without flash-of-unstyled content.
06JavaScript
Code-splitting & tree-shaking
Route-based splitting and dead-code elimination shrink what ships on first load.
07Delivery
Edge caching & CDN configuration
Cache-control rules and edge delivery reduce repeat work and shrink global latency.
08Rendering
Font-loading strategies
font-display, subsetting, and preloading eliminate invisible text and layout jumps.
09Governance
Third-party script governance
Analytics, chat, and ad scripts get audited, deferred, or sandboxed to protect the main thread.
10Governance
Performance budgets in CI/CD
Bundle size and metric thresholds block merges that would silently regress speed.
11Monitoring
RUM dashboards
Field data from real visitors shows what lab tools miss across devices and networks.
12Monitoring
Synthetic Lighthouse monitoring
Scheduled synthetic runs catch regressions on key pages before real users hit them.
Industries We Optimize
Speed programs shaped by how
each business earns its traffic.
Where slowness costs revenue differs by industry—we tune priorities to match.
Why ShubhDigi Performance
Speed engineering with
business outcomes attached.
You get more than a Lighthouse score—you get fixes tied to conversion, rankings, and retention.
Diagnostics before fixes
Real user data and root-cause analysis guide priorities—no guesswork or plugin roulette.
Full-stack remediation
Frontend, backend, and infrastructure fixes together, because speed rarely lives in one layer.
Budgets that prevent regression
CI gates and monitoring keep the next sprint from quietly undoing this quarter's gains.
Outcomes, not vanity scores
Conversion, bounce, and ranking impact are tracked alongside LCP, INP, and CLS numbers.
India advantage, global standards
Strong engineering capacity with clear reporting that works for distributed stakeholders.
Connected platform services
SEO, redesign, and cloud infrastructure expertise when speed work touches those systems too.
