Start here: my most substantial product, backend and AI work. Deployed projects include a live demo; local-only projects link to their setup instructions.

A complete booking experience, backed by an ownership-safe seat-allocation workflow.

• Searchable movie/live-event discovery, city selection, favourites and recommendations.
• Accessible seat maps, atomic holds, expiry, server-calculated totals and QR tickets.
• FIFO waitlists with single-use offers, cancellation and live inventory through SSE.
• Customer, organiser and administrator workflows, reports and audit history.
• Durable background jobs, retry scheduling and automated API/browser regression tests.

Natural-language questions become bounded analytical plans, evidence and human-review workflows.

• Query-aware orchestration selects relevant tools and explains why others were skipped.
• Rules, statistics, Isolation Forest and graph analysis support explainable risk scoring.
• Governed datasets, model provenance, investigation traces and reviewer audit history.
• Human escalation remains explicit: investigative leads are not regulatory decisions.

Task planning, telemetry, safety alerts, incident handling and cited operator guidance in one prototype. Deterministic safety rules take priority over ML/LLM output; synthetic telemetry is labelled as demonstration data.

DepShield AI combines npm audit/OSV evidence, dependency topology, bounded static reachability, contextual risk, remediation simulation, policy gates and SBOM exports. Scores are project heuristics—not proof of exploitability or a security certification.

_{Featured work is curated rather than an exhaustive list of forks, experiments or private repositories. Local-only projects are labelled instead of given invented deployment links.}

I work across frontend, backend and applied AI. I enjoy engineering problems where details matter: concurrent state changes, role-based access, database consistency, secure model integrations and recovery from partial failure.

• Currently building: full-stack products, explainable AI workflows and reliable backend systems.
• Interested in: API architecture, distributed state, system design, accessible interfaces and connected applications.
• Open to: Software Engineer Intern, Full-Stack, Backend and Applied AI/ML opportunities.
• Engineering mindset: Build → Test → Understand → Improve.

A polished interface matters. So do the behaviour under invalid input, unavailable services and simultaneous users—and the documentation that makes those tradeoffs clear.
