The scope covers every facet of testing—functional flows, edge-case handling, compatibility across browsers and devices, and overall user experience—so the work may include a mix of manual scenarios, scripted automation, and basic performance checks. Clear, reproducible documentation is essential. I will supply access to the latest build, a feature overview, and existing user stories. You will explore, verify, and report back on anything that could block a smooth launch, then retest once fixes are deployed. Deliverables • A concise test plan outlining coverage strategy • Well-structured test cases (or automated scripts) with pass/fail results • A tracker o...
I have an app moving rapidly toward release and I want a fresh, methodical set of eyes to validate every screen, workflow, and edge-case before it reaches users. You will take full ownership of quality assurance—planning the test strategy, running focused cycles, and guiding me on anything that could compromise stability or user experience. The exact blend of techniques is up to you. If a deep manual sweep is the fastest way to uncover usability flaws, let’s do it. Should automated regression or performance stress-tests add real value, I’m happy to lean on tools such as Appium, Selenium, or JMeter. Whether the build targets iOS, Android, or both, your process should fit naturally into the current development rhythm. Deliverables • A concise test plan outlining scop...

I use ActiveCampaign and I’m ready to automate my onboarding flow. The goal is to build a clean, reliable sequence that sends a warm welcome the moment someone joins my list and then follows up with timed messages that keep the conversation going. Here’s exactly what I need you to handle: • Workflow architecture – set up the triggers, tags, and list segmentation so new subscribers enter the welcome series automatically and then move seamlessly into the follow-up sequence. • Email scheduling – map out and configure the send delays (hours, days, or specific dates) so every touchpoint feels natural. • Template connection – plug my existing branded templates into the automation or create simple placeholders I can swap later. • Testing &...
I’m assembling a small toolkit to speed up penetration-testing engagements and want lean, well-documented scripts in both JavaScript (browser or Node) and Python. The focus is offensive OSINT: harvesting publicly available data, mapping an organisation’s web surface, and producing quick proof-of-concept exploits or reports that I can drop straight into an assessment. Core scope – Automate open-source intelligence collection (DNS, subdomains, metadata, common misconfigs). – Chain findings into actionable steps that demonstrate real-world impact, not just raw data. – Keep each script portable: zero external dependencies when reasonable; otherwise pin versions and explain installs. – Provide clear in-line comments so I can tweak payloads during liv...

My team ships client-facing web applications every week and I need an experienced tester who can jump in on a part-time basis to keep quality tight release after release. You will own the entire test cycle for each build, running functional, usability and performance passes across the current browsers and devices we support. You’ll write lean test cases, execute them, log any defects with clear reproduction steps and evidence, then verify fixes before we push to production. I typically queue up two to three small releases a week, so expect roughly 10–15 hours of work spread across Monday–Friday; timing is flexible as long as critical issues are reported before the daily stand-up. Key deliverables for every sprint: • Compact test plan covering functional, usability ...

I have a small web-based application that needs its security posture checked right away. The goal is to build an automated suite that performs penetration-style tests each time the app is deployed, flagging anything that could be exploited before it reaches production. Scope – The work is limited to security testing; I do not need functional or performance checks at this stage. – Within security, the emphasis is on penetration testing methods: automated discovery of common weaknesses (SQLi, XSS, auth bypass, misconfigurations) and clear proof-of-concept steps. Tech expectations Python with Selenium, Playwright, or a comparable headless browser tool is fine, and I’m open to OWASP ZAP or similar APIs if that speeds things up. Please wire the tests so they can be tri...
