PERFORMANCE CONSULTING
01
Banking DEM Implementation
Indian Banking

Large-scale banking users were dropping off during login and fund transfer journeys, while frontend JS errors and latency issues remained invisible to the internal teams for long periods.

Outcome
Implemented full Dynatrace RUM, session replay, and synthetic coverage. Frontend issue detection dropped from hours to minutes, enabling proactive UX fixes on high-friction journeys.

Enterprise Mobile Application
Enterprise Tech

An enterprise operations team required a reliable cross-platform mobile app with offline usage, real-time sync, and smooth performance on low-end field devices.

Outcome
Delivered a Flutter Android + iOS application with offline-first architecture, Firebase sync, and production crash tracking — reducing load time by nearly 40% over the earlier workflow.

WEB PERFORMANCE
03
E-commerce Performance Audit
E-commerce

The client’s e-commerce storefront was failing Core Web Vitals badly, with poor mobile loading speed, unstable layout shifts, and a PageSpeed score hurting both SEO and conversions.

Outcome
Optimised frontend assets, render flow, and image delivery — improving PageSpeed from 28 to 81, cutting load time by 75%, and reducing bounce rate within the first month.

FRONTEND MONITORING
04
Synthetic Monitor Setup
BFSI Sector

Critical outages on customer-facing banking journeys were only discovered after complaint spikes. The client lacked proactive visibility across key transaction flows.

Outcome
Built synthetic monitoring across 12 business-critical journeys with automated alerting and dashboard visibility, helping internal teams detect failures an average of 18 minutes earlier.

Client feedback

Trusted across consulting and delivery work

Feedback gathered from direct client engagements, delivery collaborations, and consulting assignments.

Suraj helped us structure Dynatrace DEM visibility in a way our internal teams could actually use. The dashboards, synthetic coverage, and replay insights made issue detection much faster than before.

Digital Program Lead
Enterprise Banking Client

The mobile app delivery was smooth, stable, and far more structured than our earlier vendor experience. Communication was clear, timelines were respected, and the final build was production ready.

RK
Startup Founder
Product Build Engagement

We initially only wanted a speed audit, but the optimisation recommendations directly improved our mobile browsing experience and reduced bounce significantly after implementation.
