Vaibhav Lalwani / SYSTEMS·26 Résumé

Available for selected roles Instructor, Robocode UK Liverpool, UK MSc Data Science & AI

AI systems that hold up in the real world.

I design and ship production LLM applications, retrieval pipelines and agent products, end to end — from evaluation and backend architecture to interfaces people can trust.

NEW / 2026 build ledger

Built to ship. Built to win.

The newest systems in the portfolio: agent markets, model workforces, local creator infrastructure, settlement safety and voice-first learning. Every link below goes to something you can inspect.

🏆 SharedOS Hackathon · Judges’ Pick 2026

Newest flagship · Agent commerce

Yuzu

The market where agents hire agents.

Give Yuzu a goal and a budget. Agents discover sellers, bid, prove capability, negotiate, contract, execute, verify and settle, with signed receipts recording exactly what happened and which permissions were used.

discover→bid→prove→negotiate→contract→execute→verify→settle

02LOCAL-FIRST

VYREALM

A Windows creator studio that turns footage and ideas into editable video projects. Timeline edits, captions, narration, local media and real exports stay on the machine, with optional MCP and model workflows layered on top.

VerifiedInstalled desktop editing and export workflow
03PAYMENT SAFETY

ReqKeeper

Exactly-once settlement for Request Network obligations through KeeperHub. Retries are allowed; duplicate money movement is not. The proof includes independent processes racing the same obligation and live Sepolia settlement evidence.

04VOICE AI

VIVA

Study out loud. VIVA transcribes what a learner says, identifies the gap, grounds the correction in source material and brings the weak concept back for active recall. Built for AssemblyAI Voice Hackathon Week.

01 / Selected work

Proof, not prototypes.

Five systems that show how I think: hired model workforces, temporal agent memory, grounded answers, memory integrity for agents, and knowledge interfaces that make complex data usable.

02 / MEMORY
Lacuna: memory fragments reorganising into current facts, superseded facts, contradictions and evidence Hack Hydra 2026 · Track 3
Hack Hydra 2026 · HydraDB · Track 3

Lacuna

Temporal, provenance-first memory for AI agents on HydraDB. It keeps every claim tied to its source sentence, preserves corrections instead of overwriting them, surfaces disagreements and abstains when the evidence is missing, over web, CLI, API and MCP.

Outcome453 graph nodes, 682 relationships, a 64-question evaluation answered identically over MCP stdio, MCP over HTTP and the CLI, 1,393 unit tests.

03 / RETRIEVAL
QueueProof workspace: a cross-source question answered with numbered claim citations back to their source records Winner · Connectors Hackathon
HydraDB × Connectors · Winner · 2026

QueueProof

An evidence-backed workspace for asking one question across multiple work sources. Every supported claim opens back to the exact record behind it, so the answer is inspectable instead of merely confident.

OutcomeHydraDB × Connectors Hackathon winner. Provenance sits inside the answer, not on a separate audit screen.

HydraSentry: a memory-integrity firewall catching a poisoned memory before an agent acts on it Winner · Build Blitz
Agent memory integrity · 2026

HydraSentry

A memory-integrity layer that checks retrieved context before an agent acts. It surfaces suspicious provenance, blocks unsafe execution and produces a signed integrity certificate for review.

OutcomeHydraDB Build Blitz winner, built as a solo end-to-end system.

Qyntra: a personal knowledge workspace with a 3D galaxy view of connected files Finalist · Wikithon
Personal knowledge system · 2026

Qyntra

A personal knowledge system that turns uploaded material into grounded answers and a navigable 3D relationship map. It makes the source landscape visible instead of hiding retrieval behind a chat box.

// / Under load

Built for the wave,not the calm.

Rate limits, bad data, a worker that dies mid-task. The systems I ship are designed for the moment the traffic turns, not the demo.

02 / About

Where models meet systems.

I am an AI systems engineer and MSc Advanced Data Science & AI student at the University of Liverpool.

I work across the full product path: retrieval and evaluation, model orchestration, APIs, data, deployment and the interface that exposes the evidence. The goal is not an impressive prompt. It is a system that behaves clearly when the input is messy, a dependency fails or a user asks “why?”

I am currently open to UK part-time AI/software roles and internships, plus graduate opportunities from 2027.

  1. 01
    Ground the answer

    Trace outputs to sources, evaluations or observable system state.

  2. 02
    Design the failure path

    Make fallbacks, limits and uncertainty visible before they become incidents.

  3. 03
    Ship the whole experience

    Architecture and interface are one product, not two separate demos.

03 / Experience

Where I've shipped.

Aug 2026 – Present Part-time · Liverpool, on-site

Instructor · Robocode UK

  • Teaching coding and robotics to young learners in Liverpool, the same curriculum ground that shaped Kodro.
Apr – May 2026 Part-time · Remote

AI Engineer, Full-Stack · Meta Solution Technologies

  • Built an AI-guided admissions platform for international students applying to UK and US universities.
  • Chat-style assistant with locked system prompts and Zod-validated structured outputs; prompts versioned and regressed against a fixed eval set before each rollout, with traces for every turn.
  • RAG on Postgres and pgvector with retrieval scoring, reranking and citation-aware generation.
  • BullMQ and Redis queue for document checks and email triggers; Docker and GitHub Actions for CI; Vercel and GCP Cloud Run for hosting; LangSmith, Sentry and PostHog for what happens after a deploy.
  • Supabase auth (OAuth, magic link, PKCE), a 10-language i18n layer and a dual-theme CSS layer the rest of the team could ship copy through.

04 / Recognition

Wins & security work.

Hack HydraDB · two authorised security rounds

Two separate authorised engagements against HydraDB. One placed top 3 in a competitive hack; the second was a structured owned-tenant assessment. Reported through coordinated disclosure; sensitive specifics withheld.

Round 01 · Hackathon Top 3 of 20+

Hack HydraDB

Found an authentication / credential-handling weakness reachable without proper authorisation. Placed in the top 3 of a field of 20-plus.

Technical specifics, payloads, and affected endpoints withheld under responsible disclosure.

Round 02 · Bug bash 6 defects

Hack HydraDB · July

Authorised read-only assessment of an owned tenant. Filed 6 reproducible defects across reliability, input validation, and API-contract correctness. Tenant isolation held throughout, with no data exposure; the core security proved sound.

Defect detail shared privately with the maintainers.

Position paper · corrected v2

NEXUS

The corrected version 2 presents the architecture and analytical latency model without claiming prototype or gameplay-corpus results. It also repairs the citation error documented after v1.
