Reamogetswe Molefe

Early-career AI and full-stack developer and second-year BEngTech Mechanical Engineering student building AI, SaaS, and fintech systems with modern AI-assisted engineering workflows. Hands-on with Python, TypeScript, JavaScript, React/Next.js, Node.js/Express, REST APIs, PostgreSQL/Supabase, and LLM APIs. Uses AI coding tools for rapid prototyping, debugging, refactoring, and testing while owning architecture, integrations, validation, and product decisions.

Creator of Kohort and CreatorCashFlow, with additional full-stack, mobile, and ML projects.

Founder & Lead Engineer at Kohort (2026 – Present)

AI market-research engine for controlled synthetic concept testing

• Architected a multi-stage Python pipeline through OpenRouter: live web research, deterministic persona sampling, persona generation, two-stage interviews, analytics, critic review, and report generation.
• Built asynchronous workflows supporting concept tests with up to 200 synthetic personas per run using controlled concurrency, retries, Pydantic validation, JSON repair, and per-run cost controls.
• Implemented deterministic Python analytics for Van Westendorp pricing, calibrated purchase intent, segmentation and diagnostic flags, keeping quantitative calculations outside the LLM layer.
• Integrated Perplexity, DeepSeek, and a Jev System One critic; probabilistic critic flags severe data-quality risks while stage success gates abort unreliable persona/interview runs.

Founder & Developer at CreatorCashFlow (2025 – Present)

Full-stack SaaS for creator-agency campaign operations and financial visibility

• Built a working full-stack MVP and modular REST API using JavaScript, Node.js and Express, with Supabase/PostgreSQL for application data.
• Implemented JWT/bcrypt authentication, CORS/Helmet security foundations and a Gemini service layer with PII masking for AI-assisted workflows.
• Created automated integration/UI contract tests and a concurrent-request stress harness; manage the codebase with Git/GitHub and iterate from product feedback.

Full-Stack Developer at Yieldly (2026 – Present)

Next.js/TypeScript fintech prototype for digital stokvels and goal-based saving

• Built a Next.js/React/TypeScript frontend with multi-step onboarding, dashboard views and stokvel-oriented workflows.
• Implemented an Express REST backend with JWT authentication, bcrypt password hashing and LowDB persistence for users, stokvels, memberships and payments.
• Designed a clear frontend/API boundary and fintech UX while keeping investment-allocation previews explicitly theoretical and prototype-only.
