Web App Load & Stress Testingg

@mninfotech2

Hi,Before releasing a web or mobile application, it’s important to know how it behaves when real users start putting pressure on it. I can take ownership of this testing and give you clear data on where the application slows down, fails, or becomes unstable. I have done similar work in performance testing, API testing and mobile application QA. I can work with your Swagger/Postman APIs, authentication setup and Crashlytics/Sentry data to build realistic testing scenarios. I’ll test normal traffic as well as peak, spike and long-duration loads, monitor response times, throughput, errors and resource usage, and investigate mobile crashes across devices and OS versions. Rather than providing a report full of raw test results, I’ll highlight the issues that actually matter, explain their likely impact and prioritize the fixes your development team should address first. You’ll receive the complete test plan, execution results, graphs/tables, crash analysis and actionable recommendations. I can also share relevant testing reports or previous work in chat. If the initial engagement goes well, I’d be happy to continue with regression and release-cycle testing.

For this engagement, I’d start by separating backend performance testing from mobile stability analysis, then correlate the two where load spikes coincide with elevated API failures, ANRs, or crash clusters. My two priorities would be scalability and maintainability. I’d define realistic k6 or JMeter scenarios for normal load, peaks, spikes, and soak runs against authenticated REST flows, capture p50/p95/p99 latency, throughput, error rates, and infrastructure usage, then review Crashlytics/Sentry by crash cluster, device, OS version, and release. The outcome would be a prioritized remediation list tied to measurable evidence rather than generic tuning advice. I’d also compare staging vs production first, especially data volumes, caching, rate limits, third-party integrations, worker counts, and infrastructure sizing, because load-test results are only useful when the environments are representative. A relevant project is Mohollla, a production quick-commerce ecosystem with customer, driver, shop-owner, and admin apps running across Android/iOS, where stability across multiple user flows and live operational traffic was a key concern. I can structure the first cycle as: test plan, execution/logs, crash analysis, findings review, then a regression pass after fixes.

@softhunters

The goal is to identify where your application breaks under real traffic and which mobile issues repeatedly cause crashes, then turn the data into clear engineering actions. I can handle: ✅ Load, stress, spike and soak testing ✅ Authenticated REST API performance testing ✅ JMeter, k6, Gatling or Locust ✅ Realistic traffic and peak-load scenarios ✅ Response time, throughput and error-rate analysis ✅ Server/resource utilization monitoring ✅ Swagger/OpenAPI or Postman-based testing ✅ Staging vs production gap analysis ✅ Crashlytics/Sentry crash analysis ✅ Crash clusters by device and OS version ✅ Crash-free sessions and recurring stability issues ✅ Correlation between load and failures ✅ Detailed logs, graphs and performance tables ✅ Prioritized bottleneck and crash-fix recommendations My workflow is environment review → test plan → baseline → load/stress/spike/soak → crash analysis → bottleneck identification → recommendations → final report. I’ll document test assumptions and limitations clearly so the results can support practical development decisions. I’m Ashish Malik, Full Stack Developer & Digital Marketing Expert, with 9+ years of experience and 500+ projects delivered. I won’t fabricate reports or case studies. I can share relevant examples where available and clearly demonstrate how I would structure the testing and reporting. If you need testing that shows what fails, when it fails and what should be fixed first, let’s start a chat.

@chetanprajapat

I’ve reviewed the scope carefully, and the important part here is turning the test requirements into measurable evidence—not just generating traffic and calling the run complete. I can structure the work around baseline/load, stress, spike and soak scenarios for the authenticated REST APIs, with clear thresholds for response time, throughput and error rates. I’d first validate the staging/production differences and API assumptions, then execute controlled tests and correlate the results with server/resource behavior. For the mobile side, I can review the supplied Crashlytics/Sentry data to identify recurring crash clusters, affected OS/device patterns and trends that may coincide with backend pressure. The final report can consolidate the test plan, execution data, graphs/tables, bottlenecks and prioritized remediation recommendations so your development team has clear next actions. I don’t want to claim specific JMeter/k6 case studies that aren’t documented in the supplied portfolio, but I can work from your Swagger/OpenAPI or Postman collection and the available monitoring data. Share the API collection and test environment details, and I can define the initial test matrix.

@Shrutibimpl

Hello, I can conduct the performance testing for your web application and analyze the mobile stability reports from Crashlytics and Sentry. My plan is to review your Swagger or Postman collections to build automated load, stress, spike, and soak test scripts using k6 or Locust. I can audit your staging environment to identify parity gaps against production before testing begins. I can execute authenticated REST API tests to measure throughput, response times, and error rates under heavy concurrency. Simultaneously, I can review your Crashlytics and Sentry dashboards to isolate recurring mobile app crashes and correlate them with high traffic loads or specific device operating systems. Finally, I can deliver a clear report with actionable recommendations for performance optimization. In a past project I conducted API load testing with k6 and analyzed mobile crash logs in Sentry to resolve performance bottlenecks for an e-commerce platform. 1) Which tool such as k6 Locust or JMeter do you prefer for scripting the authenticated REST API performance tests? 2) Are the mobile apps built natively in Swift and Kotlin or using a cross-platform framework like Flutter or React Native? 3) Does your staging environment have similar database scaling and server specs compared to production? Thanks, Bharat

@Hrolgar

Are the load and stress runs hitting the same backend the mobile app talks to, or is that a separate API from the crash data? If it's the same one, I can build the load profiles straight off real crash timestamps instead of guessing at correlation afterward. My plan is to pull your Swagger or Postman collection first and write the JMeter or k6 scripts directly against the real endpoints and auth flow, not a generic template. Load and stress establish the baseline and breaking point, then spike and soak build on that. Alongside it I go through the Crashlytics and Sentry exports, cluster the crashes by frequency, device, and timestamp, and map those clusters against whatever load was running at the time. One report comes out of it, not two: test plan, execution log with graphs and tables, and a single prioritized fix list where each item ties back to either a measured threshold or a crash cluster, whichever is worse. M1: Test plan and script build off your API docs and auth flow, 21120 INR, 2 days. M2: Load, stress, spike, and soak execution plus the crash clustering pass, 25000 INR, 3 days. M3: Correlation report and prioritized fix list, 17880 INR, 1 day. Is the crash data available as a raw export, or only through the dashboards?

I will build a realistic performance test plan for your authenticated REST APIs and web application, covering baseline, load, stress, spike, and soak scenarios with measurable response time, throughput, error rate, and resource utilization. I will validate your Swagger/OpenAPI or Postman collection, configure authentication and test data, then execute the tests using JMeter, k6, Gatling, or Locust based on your architecture and traffic patterns. Before execution, I will compare staging vs production configuration and flag differences that could invalidate test results, including infrastructure, database, caching, integrations, and rate limits. For mobile, I will analyze Crashlytics/Sentry data to identify recurring crash clusters, affected devices/OS versions, crash-free sessions, and correlations with backend performance or high-load conditions. I will provide graphs, tables, execution logs, bottleneck analysis, and prioritized fixes. In similar testing work, I have resolved issues such as API latency from inefficient queries, connection-pool exhaustion, cache misses, and traffic-related failures by correlating load-test metrics with server behavior.

@Visharaa2024

Hi there, This project needs more than simply running a load test, the useful outcome is correlating API performance, infrastructure saturation and mobile crash patterns into actionable findings. I can structure the engagement around a baseline/environment review first, followed by realistic load, stress, spike and soak profiles against the authenticated REST APIs. Using the agreed toolset, I’ll capture p50/p95/p99 response times, throughput, error rates, concurrency and available CPU/memory/database metrics. For the mobile side, I’ll analyze Crashlytics/Sentry data by crash cluster, app version, device and OS, then look for timing or release correlations with backend performance issues where the data supports it. The final deliverable will include the test plan, execution evidence/graphs, crash analysis and a prioritized remediation list with findings tied to measurable data, not generic recommendations. I can provide relevant sample reports/case studies where available. Question: What infrastructure metrics are currently available during testing (CPU, memory, database, etc.), and is the performance environment production-like? Best regards, Deepak.

@MuhammadAkif8

Do you already have baseline performance targets for response time and throughput? The main challenge is generating reliable performance data under normal load, peak traffic, spikes, and long running sessions while also connecting API performance with mobile crash trends. I would create realistic JMeter or k6 scenarios for authenticated REST APIs, measuring response time, throughput, error rate, and server resource usage. I would review Crashlytics or Sentry data for recurring crashes, affected devices and OS versions, then compare findings with load conditions and identify staging versus production gaps. The final report will include test logs, graphs, crash data, bottlenecks, and prioritized fixes. Best regards, Akif U.
