PERFORMANCE PRESSURE
Slow products rarely have one slow thing.
Visible lag can be caused by rendering, JavaScript, network waterfalls, service-to-service latency, database contention, cache misses, third-party dependencies or infrastructure saturation. We measure the whole path before changing architecture.
01Experience symptomsSlow loading, delayed interaction, visual instability or app jank.
02System symptomsLatency spikes, queue growth, timeouts, lock contention or resource pressure.
03Business symptomsAbandonment, failed journeys, lower conversion or rising cloud cost.
PERFORMANCE SCORECARD
One programme. Six measurable layers.
We create a baseline at the layers users actually touch and the layers engineering teams need to control.
Frontend delivery
Bundles, media, fonts, caching, rendering and main-thread work.
Application services
API latency, queues, concurrency and dependency timing.
Data layer
Queries, indexes, locks, cache hit rate and connection pressure.
Infrastructure
CPU, memory, network, autoscaling and regional placement.
Capacity
Throughput, saturation, recovery and headroom under load.
PERFORMANCE OPTIMIZATION SERVICES
Optimization across the complete user-to-infrastructure path.
Engage AppsLoading for a full performance programme or a focused bottleneck across one layer of the product.
PERFORMANCE DIAGNOSTICS
Follow one request from tap to database and back.
Instead of tuning isolated components, we connect browser or app timing to APIs, dependencies, data access and infrastructure. That reveals where time is actually being spent.
01ClientRender, interaction, memory and network.
02EdgeDNS, CDN, compression and cache.
03APIRouting, middleware, services and queues.
04DataQueries, indexes, locks and connections.
05CloudCompute, network, scaling and regions.

CORE WEB VITALS
Improve field performance where real users actually feel it.
We connect CrUX or RUM evidence with lab profiling, network waterfalls and render analysis so LCP, INP and CLS work is based on the cause rather than the score alone.
LCPServer response, render-blocking work, image priority and caching.
INPMain-thread tasks, JavaScript execution, event work and rendering.
CLSDimensions, late content, fonts and layout movement.
Field segmentationDevice, geography, template and traffic-source differences.

FRONTEND PERFORMANCE
Make the browser do less work for every interaction.
We profile the main thread, JavaScript execution, layout, rendering, asset delivery and network waterfalls to remove work that users pay for on every visit.
Bundle strategyCode splitting, lazy loading and third-party reduction.
Image deliveryFormats, sizing, priority and responsive sources.
RenderingHydration, long tasks, layout and paint.
Cache policyBrowser, edge and immutable asset strategy.
API & BACKEND LATENCY
Reduce time spent between request received and useful response.
Backend performance often hides inside serial calls, chatty services, queue delays, external dependencies, inefficient serialization and work that should happen asynchronously.
01Trace the critical pathFind which service or dependency owns the latency.
02Remove unnecessary workBatch, cache, parallelize or move work off the request path.
03Protect dependenciesTimeouts, retries, circuit breakers and graceful fallbacks.
DATABASE PERFORMANCE
Fix the queries and contention that slow everything above them.
We use query plans, wait events, index analysis, connection behavior and workload patterns to improve the data path without blindly adding infrastructure.
Slow queriesPlans, filters, joins and scan reduction.
IndexesCoverage, selectivity and write trade-offs.
ConcurrencyLocks, transactions and hot records.
Connection pressurePooling, limits and saturation behavior.
MOBILE APP PERFORMANCE
Mobile performance is startup, rendering, memory and network together.
We optimize the experience across real devices and weak networks, not only a powerful development machine.
Launch time
Reduce blocking initialization, heavy startup work and unnecessary SDK setup.
Rendering & jank
Profile frames, list rendering, state updates and expensive visual work.
Memory & stability
Find leaks, pressure, crashes and lifecycle issues across device classes.
Network efficiency
Reduce payloads, retries, duplicate calls and slow request chains.
CLOUD PERFORMANCE & COST
Performance and cloud efficiency should improve together.
More compute can hide inefficient work. We separate capacity problems from architecture problems and tune the platform around actual traffic and utilization.
Right-size computeCPU, memory, utilization and workload profile.
AutoscalingThresholds, warm-up and burst behavior.
Regional latencyPlacement, edge and cross-region traffic.
Unit costCost per request, customer or transaction.
CACHE, CDN & DELIVERY
Do not recompute or retransmit what can be served closer and faster.
We design cache layers around data freshness, invalidation, personalization and failure behavior so performance gains remain correct and operationally safe.
01Browser & edge cachingTTL, cache-control and immutable asset strategy.
02Application cachingHot data, expensive operations and invalidation logic.
03CDN deliveryCompression, images, regional delivery and origin protection.
LOAD & STRESS TESTING
Know the limit before real traffic discovers it for you.
We model realistic traffic, concurrency and business journeys to identify saturation points, queue growth, timeouts and recovery behavior.
Throughput vs saturation
CAPACITY PLANNING
Turn traffic forecasts into engineering headroom.
Capacity planning connects business forecasts to throughput, concurrency, service limits, queue behavior and infrastructure resources.
Traffic modelUsers, transactions, journeys and arrival rate.
HeadroomSafe operating range before saturation.
Dependency limitsDatabases, providers and third-party quotas.
Failure behaviorWhat degrades first and how the system recovers.
PERFORMANCE OBSERVABILITY
Protect performance with production evidence after release.
Optimization is incomplete without visibility. We connect metrics, traces, logs, RUM and business events so regressions can be caught quickly.
RUMReal users, devices and geography.
APM & tracesService latency and dependency timing.
InfrastructureResource pressure and scaling behavior.
Business journeysPerformance of checkout, signup or critical workflows.
P95 API212 ms↓ 38% since baseline
PERFORMANCE BUDGETS
Stop speed from quietly regressing release by release.
We convert target performance into build and production guardrails so new code, scripts, media or dependencies cannot erode the gains unnoticed.
01Frontend budgetsBundle size, long tasks, LCP and interaction thresholds.
02API budgetsP50, P95 and P99 latency with error-rate guardrails.
03Load regression testsCompare releases under repeatable traffic scenarios.

What does performance optimization include?
It can include frontend speed, Core Web Vitals, API latency, database tuning, mobile performance, cloud efficiency, load testing, capacity planning and observability.
How do you identify the real bottleneck?
We combine field data, lab tests, profiling, traces, logs, database analysis and controlled load testing so recommendations are supported by evidence.
How long does a performance engagement take?
Timing depends on product complexity, current observability, the number of slow journeys and whether implementation and load testing are included.
Can you improve Core Web Vitals?
Yes. We improve LCP, INP and CLS through rendering, asset, script, caching, server-response and layout changes based on field and lab evidence.
Can performance optimization support SEO?
Improved Core Web Vitals, page experience, crawl efficiency and loading behavior can support the technical quality of a site.
Can you optimize complex React or web applications?
Yes. We can profile rendering, state updates, bundles, network requests, long tasks and API dependencies in interactive applications.
Can you optimize slow APIs?
Yes. We review service logic, dependencies, database access, queues, caching, timeouts, serialization and infrastructure.
Can you optimize database performance?
Yes. We review queries, plans, indexes, schemas, locks, transactions, connections, caches and workload patterns.
Can third-party services be part of the analysis?
Yes. We measure dependency latency and can reduce its impact through timeouts, caching, batching, asynchronous work and fallback design.
Do you perform load and stress testing?
Yes. We can test concurrency, throughput, saturation, spikes, endurance, failure behavior and recovery using realistic scenarios.
Can performance work reduce cloud cost?
Often. Removing inefficient work, improving caching, right-sizing resources and tuning scaling can reduce the cost required for the same workload.
