Hands-on session focused on improving your backend system quality, reliability, and performance. What’s included: API testing (REST, contracts, edge cases) Debugging real issues (logs, DB, services) Test automation guidance (Java, REST Assured, JUnit/TestNG) PostgreSQL queries & data validation Architecture & performance insights Root cause analysis of production issues Typical use cases: Your API returns errors or behaves inconsistently You need proper test coverage but don’t know where to start You want to debug a complex issue quickly You need a second opinion on system design Outcome: clear understanding of the problem + practical solution or next steps.
Practical engineering help for real-world problems — not just theory. What’s included: Software setup & configuration (apps, tools, environments) Hardware & electronics troubleshooting (basic repairs, diagnostics) PC / laptop issues (performance, errors, setup) Network / home tech problems General “something is broken — help fix it” cases Also possible: Structured tasks requiring precision (assembly, technical work) LEGO-style builds or detailed manual work Combining software + hardware solutions Approach: Identify root cause Provide clear fix or implement it directly Keep things simple and working Best for: When something doesn’t work and you don’t want to waste time When you need a practical, hands-on mindset Pricing depends on complexity for larger tasks.
Senior QA Engineer / SDET with strong backend and system-level expertise — and a practical, hands-on mindset beyond pure software. I design reliable test automation frameworks (Java, JUnit/TestNG, REST Assured), validate complex REST APIs, and debug issues across full systems (API → DB → integrations). Experienced with microservices, workflows, messaging, and PostgreSQL-based validation. Domain experience includes: Booking / rental systems Payments & invoicing flows Integrations with external services (APIs, providers, workflows) Production-heavy environments where correctness matters Core strengths: API testing & contract validation Test automation architecture (clean, scalable, maintainable) Root cause analysis (logs, DB, system tracing) Turning unclear requirements into precise test scenarios Performance-aware thinking (queries, data access, system load) In addition to software, I can operate as a real-world problem solver: Hardware & electronics troubleshooting / repair Software setup, configuration, and debugging Practical engineering tasks requiring “hands + brain” Structured, detail-oriented work (including LEGO-level precision where needed) I combine engineering thinking with hands-on execution. If something is broken — I can usually figure out why and fix it. Pricing is flexible and depends on task complexity, timeframe, scope, and expected outcome.
