QA ENGINEER / SDET
QA Engineer / SDET focused on test automation, quality engineering, developer tooling, and AI-assisted testing.
I work across web, Electron desktop, Android, APIs, databases, and CI/CD - turning repetitive QA work into frameworks, utilities, and smarter validation systems.
Most bugs hide where nobody thinks to look. That is where I like to work.
I work at the intersection of software testing, automation, developer tools, databases, and AI. My focus is making QA faster, more repeatable, and more engineering-driven.
I currently work at Vyapar as a Senior Quality Engineer, across product testing, Playwright automation, Electron desktop workflows, database validation, internal QA tooling, and AI-powered approaches for complex validation work.
My default question is simple: if a problem repeats, can we build a tool or automation system that solves it permanently?
Built repeatable QA systems, automation, and validation workflows for high-impact Vyapar releases.
Improved enterprise release readiness through structured UAT, regression testing, and API validation.
Built a strong QA foundation across test design, execution, automation basics, and stakeholder reporting.
ProblemMobile QA and debugging often require checking local data, but inspecting SQLite files directly from a device is usually slow and inconvenient.
What I builtRead-only Android workspace for SQLite database analysis with table browsing, schema inspection, filtering, sorting, SQL query execution, JSON viewing, CSV/Excel import, and data export support.
ImpactHelps developers, testers, and analysts validate local data securely on-device during QA, debugging, and customer issue investigation.
ProblemQA often needs to answer one question fast: what exactly changed between two databases?
What I builtDatabase comparison utility with table/data comparison, visual difference inspection, filtering, and date/time handling.
ImpactTurns repetitive QA investigation into a faster validation workflow for QA, support, tech, and data teams.
ProblemQA and data teams often need spreadsheet comparison without uploading sensitive workbooks to a server.
What I builtPrivacy-first Excel comparison tool that compares workbooks cell-by-cell, highlights added, deleted, and modified data, supports smart filtering, and exports reports to Excel, PDF, and CSV.
ImpactRuns 100% client-side, so sensitive spreadsheets stay on the user's machine while validation reports remain easy to share.
ProblemTraditional automation is brittle when UI structure, locators, and product states keep changing.
What I builtAI-assisted QA system exploring test planning, UI understanding, locator generation, execution, and adaptive validation.
ImpactMoves QA thinking from scripted execution toward goal-driven test planning, execution, validation, and adaptation.
ProblemDesktop apps need automation that understands windows, dialogs, app state, and database-backed behavior.
What I builtPlaywright automation approach for Electron workflows using browser contexts, Chromium internals, reusable architecture, and data assertions.
ImpactExpands Playwright beyond browser testing into practical desktop release validation.
Recognized for DB Compare Utility & Exceptional contribution to the Playwright automation framework.
Awarded for streamlining UAT processes and reducing regression cycles.
Won 1st prize in Zonal Level Robo Race.
Huge appreciation for the Sumit on Multicurrency Support! :currency_exchange: This feature had deep, complex impact - pricing, conversions, formatting, edge cases galore - and it needed rigorous testing to get right. You caught what mattered, before it ever reached users. Result? Zero production bugs since launch. :raised_hands: That's the mark of sharp, thorough testing and real attention to detail. Thank you for holding the bar high - amazing work! :rocket::clap:
Sumit has been instrumental in ensuring the quality of Smart Connect, showing strong ownership from understanding the scope to creating high-level plans and detailed test cases. His collaboration with Jithin enabled early testing and thorough validation with large datasets. He emphasizes full impact testing when major changes occur, reflecting his deep customer empathy and commitment to quality. With final refinements like fit and finish, session merging, and Mac build stabilization ahead, his high standards will continue to shape the project's success. Congratulations, Sumit - your dedication and attention to detail have been invaluable!
Sumit Singh - Driving QA Excellence in Flyy by Vyapar Sumit led both manual and automation testing for Flyy by Vyapar with diligence and depth. He introduced Playwright for automation and drove end-to-end test coverage - across multi-device, concurrency, load, and DB validations. From login (app + WhatsApp) to campaign creation/execution (desktop & mobile), template flows, contact imports, brands.live integration, and real-time status tracking - he ensured high quality across all modules. His structured test planning, proactive bug detection, and collaborative mindset made him a cornerstone of the QA success. Your leadership in QA made a huge impact, Sumit. 🚀👏
Sumit, I am proud to nominate you for the Going Above & Beyond award. Your dedication to quality, ownership, and doing the right thing even when it is hard has made a real difference to our team. You consistently dig into complex issues, find root causes, and follow through until they are fully resolved, not just patched. I especially appreciate how you proactively anticipate risks, support others without being asked, and stay calm and focused under pressure. Your work has directly improved our product stability and our confidence in every release. Thank you for always stepping up, for your reliability, and for the quiet leadership you show every day. I am genuinely grateful to have you as a teammate.
