Open to QA leadership & AI-quality roles
I'm Rahul Prajapati — QA & Automation Analyst (Acting QA Lead) at BDO Canada. I make enterprise platforms and AI agents trustworthy, and I build the agents that make testing faster.
01 — Strengths
The at-a-glance version. Every number below is one I stand behind in interviews.
My core strength in AI: I bring ideas to life — closing the gap between people who have a problem or an idea and a working solution built with AI tools, then automating it to increase efficiency and scale.
Coverage 40 → 70% · 30% less defect leakage
25% higher agent accuracy · 30% fewer bad outputs
Team of 5 · 20% productivity gain
373% ROI option chosen over 17%
02 — Case studies
Details anonymised where client confidentiality requires. Every number is one I can defend in an interview.
Problem. An ITSM virtual agent (Microsoft Teams + ServiceNow) answered employee requests using live enterprise data — and sometimes answered wrong. No playbook existed for testing it.
Approach. Built the AI/LLM testing strategy from scratch: 100+ structured prompt variations, hallucination detection, response-accuracy scoring, data-retrieval validation against ServiceNow records, and regression-safe prompt refinement.
Result. A measurably more accurate and safer agent in production, plus a reusable evaluation playbook the team still runs.
Problem. Test design was the bottleneck: manual case creation ate hours every sprint, and ambiguous requirements kept surfacing late as rework.
Approach. Engineered internal Copilot-based agents for automated test-case generation and early requirement validation — flagging ambiguity before development, not after.
Result. Test design stopped being the bottleneck; requirement gaps now surface in refinement instead of QA.
Problem. Should we build an automation framework (Playwright MCP + GitHub Copilot) or buy an enterprise platform (Katalon / AccelQ)? Opinions were cheap; the decision wasn't.
Approach. Built a six-sheet cost-benefit workbook: 3-year horizon, vendor evaluation (security certs, Entra auth, CRM integration, AI capabilities), sensitivity analysis, and a risk register — executive-ready.
Result. Clear, defensible numbers: Buy returned ~373% ROI with year-one payback against ~17% for Build. The decision made itself.
Problem. Which of two anonymous model responses is actually better? Rank them — accurately, consistently, at speed, in a 24-hour evaluation sprint.
Approach. RLHF-style pairwise preference ranking with rubric-driven scoring: accuracy, completeness, structure, instruction-following, hallucination risk — every judgment backed by a written rationale.
Result. Hands-on experience with the exact evaluation methodology behind modern model training, from the human side of the loop.
Problem. A year of knowledge scattered across nine AI accounts. How do you build one queryable brain out of it — without leaking secrets into embeddings?
Approach. Full architecture: Supabase schema (messages + chunks), 1536-dim embeddings with an HNSW cosine index, a redaction module scrubbing keys/tokens/PII before persistence, and CI/CD config.
Result. An honest lesson in product thinking: a structured markdown system solved 80% of the problem with none of the code — so that's what shipped. Full design available on request.
03 — Toolkit
Honest levels — I'd rather show you where I'm strong than pad a logo wall.
A personal finance dashboard built end-to-end with AI-assisted development, then covered by a 23-test Playwright suite running green in CI.
View repo →My studio for simple, useful AI-powered apps. Google Play developer account approved; first Android app in build — shipped in public.
Follow on LinkedIn →A personal "central brain" — finance and career dashboard with RAG retrieval over years of notes. Fully architected, then deliberately not over-built.
Design studyRebuilt an open-source AI job-search agent around my own workflow: paste a job link, get a fit score and a tailored CV with anti-fabrication guardrails, delivered over Telegram.
View repo →Concepts in the pipeline: Color Vibes, TailBlazer, a notary app, and a Bloomberg-style terminal — candidates for RunningOak's first ship.
In discoveryHands-on across agent skills, LLM-evaluation harnesses and AI tooling — staying current with how modern AI systems are actually built and tested.

Five years ago I started in QA testing municipal web apps. Today I sign off on enterprise releases and design testing strategies for AI agents that answer with live business data. The common thread: I like finding out where systems break before users do.
At BDO Canada I own quality strategy for enterprise billing and AI-enabled platforms — coordinating UAT with business stakeholders, architecting automation frameworks, implementing CI/CD quality gates, and leading a team of five QA analysts. Three internal awards along the way (two Gold Awards and a Standing Ovation).
What I'm building toward: quality leadership for AI products — the person who decides not just whether it works, but whether it should ship.
Off hours I'm usually planning the next road trip (Newfoundland icebergs, most recently), building apps, or working toward a stubborn life goal of visiting every country on Earth.
