End-to-end build · 6-person team

PathFinder AI — Advanced

OBJECTIVE

Evolved the Week 1 MVP into a full end-to-end AI product — broadened the pathway system beyond degree streams to Study / Work / Skills / Business / Not Sure tracks, added real user accounts, persistence, and moved toward a production-grade architecture.

TECHNIQUE

Full-stack rebuild with authenticated sessions, persisted chat history, and saved user pathways. Backend services built on tRPC / Drizzle ORM against a relational database, with LLM calls routed through a managed AI gateway.

IMPACT

Took the project from a single-day prototype to the team's flagship end-to-end submission by the bootcamp's final week, adding authentication, persistence, and a broader multi-track recommendation system aligned with the team's ML coursework.

SentiX — Takealot InsightEngine

OBJECTIVE

Built an aspect-based sentiment analysis and interactive data-intelligence platform for Takealot app reviews, delivering a dashboard, insights report, and technical explanation as part of the bootcamp's portfolio requirements.

TECHNIQUE

Aspect-Based Sentiment Analysis (ABSA) and urgency classification using a dual-engine approach (VADER + Hugging Face) for transparency. Interactive KPI dashboard with citation-linked chat allowing users to click a cited review ID and filter the dataset to that topic.

IMPACT

Directed a 6-person team (Researcher, 2× Backend, Frontend, UI/UX) through a full pivot in tech stack and scope, landing a dual-engine sentiment platform with 7 live KPIs, guest-accessible "Quick Analysis," and full account-gated business workspaces.

Solo concept & design

OmniLens AI

OBJECTIVE

Designed a source-grounded, multi-department project intelligence platform that ingests project documents as an immutable source of truth, flags cross-source conflicts, and generates role-calibrated artifacts (decks, posters, SOPs, flashcards) for different departments.

TECHNIQUE

Shared source pool with department "lens" applied at generation time rather than pre-sorted document buckets. Hard-conflict detection with soft advisory overrides. Cached, versioned lens outputs (by lens + artifact + source-set) flagged stale rather than auto-invalidated on source change.

IMPACT

Independently scoped and designed a full product concept end-to-end — from MVP definition through to a 5-lens, auth-enabled, analytics-integrated build spec — demonstrating solo product thinking and UX/architecture design skill outside a team structure.

PathFinder AI — Week 1 MVP

OBJECTIVE

Built an interactive diagnostic chatbot to help South African Grade 10–12 learners explore university course streams and career paths, using a lightweight prompt-based architecture deliverable within a single day.

TECHNIQUE

Prompt-based content recommendation — the LLM handled state management and recommendations via system instructions plus an embedded JSON course catalog. A 3–4 question flow (subjects enjoyed, work style, problem-solving style) generated a personalized "Career Profile" with recommended degree streams and academic advice.

IMPACT

Delivered a working diagnostic MVP within the team's single-day build window, validating the prompt-based recommender approach and setting the foundation the team carried into the Week 4 advanced build.
