Lead AI Engineer · Berlin

Faisal NaseerI build AI agents that take on the busywork — so people can do their best work.

Agentic AI engineer and technical founder with eight years of hands-on engineering leadership. I design multi-agent systems, RAG platforms and LLM evaluation pipelines that run in production — measured, secure, and with humans in charge where it matters.

01 · About

Engineer first. Builder by habit. Team player always.

My background is classic software engineering — distributed systems, high-scale platforms and 0-to-1 products for marketplaces serving tens of millions of users. Today I apply that foundation to agentic AI: multi-agent orchestration, retrieval-augmented generation and automated LLM evaluation that replace manual work in real businesses.

I'm currently building Vauris.ai, a platform that measures how brands appear in AI-generated answers across ChatGPT, Gemini and Perplexity. Before that I led AI and platform engineering at MetaDesign (Publicis Groupe), Flaconi and iCarAsia.

What I care about most is that AI makes work better for the people around it — new joiners who ramp up in days instead of a month, support teams freed from repetitive tickets, engineers who get mentoring and room to grow.

What I bring to a team

  • 01

    Multi-agent orchestration

    LangGraph, CrewAI and MCP-based systems — automation where it's earned, human-approval gates where risk is high.

  • 02

    RAG & knowledge systems

    pgvector, FAISS, Neo4j, GraphRAG, hybrid search and multimodal document reasoning — grounded, citation-backed answers.

  • 03

    Eval-driven delivery

    Langfuse, DeepEval and RAGAS gate every release on faithfulness, groundedness, latency and cost.

  • 04

    Security by design

    Prompt-injection defence, least-privilege tool authorisation, red-team suites in CI and strict multi-tenant isolation.

  • 05

    Platform & cloud architecture

    Event-driven microservices, Kubernetes, serverless and Terraform on AWS and Azure — built for scale and cost.

  • 06

    Hands-on leadership

    Technical strategy, roadmaps and teams of up to eight engineers — while still writing, reviewing and unblocking code.

02 · Case studies

Selected work, with the numbers behind it.

A few systems I've designed and shipped. Each one went to production and was measured against a clear baseline.

Showing case studies: 6

  • Vauris.aiLangGraph · FastAPI · LLM-as-judge

    Deep-research loop agent

    ~55%less manual research effort
    Challenge
    Research tasks took analysts hours of manual searching, reading and cross-checking sources.
    Approach
    A planner decomposes the question, retrieval and synthesis agents gather evidence, and a critique agent scores confidence and grounding. Below threshold the loop re-queries; after three failed cycles it escalates to a human reviewer.
    Outcome
    Grounded, citation-backed answers — and humans only step in when the system is genuinely unsure.
  • MetaDesignIntent classification · RAG · escalation routing

    Customer support agent

    6 h → 3 minresolution time, 65%+ of queries handled
    Challenge
    Customers waited 5–6 hours for answers to issues the team had often solved before.
    Approach
    Intent classification routes each query, RAG retrieval grounds the answer in documentation, and anything outside the agent's confidence is escalated to a person.
    Outcome
    Most queries answered instantly; the support team focuses on the cases that need human judgement.
  • MetaDesignMultimodal RAG · RAGAS · golden datasets

    AI Buddy — onboarding assistant

    ~1 month → daysonboarding ramp-up
    Challenge
    New joiners and team-switchers spent around a month finding their way through project documentation.
    Approach
    A knowledge base over all project docs, with multimodal reasoning over diagrams, screenshots and scanned PDFs. Validated with RAGAS before rollout, with releases gated on a faithfulness floor.
    Outcome
    People become productive in days, and token use per answer dropped ~40% through context budgeting.
  • MetaDesignMCP · per-tool authorisation · versioning

    Shared MCP server for AI capabilities

    2 wks → 2 daysto integrate a new agent
    Challenge
    Every new agent rebuilt its own integrations for retrieval, ingestion and log lookup.
    Approach
    One internal MCP server exposes per-tenant retrieval, document ingestion, log and ticket lookup as versioned tools with scoped per-tool authorisation.
    Outcome
    Adopted by four internal agents — and a compromised prompt can't widen an agent's access.
  • MetaDesignLog ingestion · anomaly detection · multi-step reasoning

    AI Ops root-cause agent

    ~30 minincident resolution, down from hours or days
    Challenge
    Production incidents took hours or even days to diagnose across noisy log streams.
    Approach
    An agent ingests structured logs, detects anomalies and runs multi-step root-cause analysis, producing a report with concrete remediation steps.
    Outcome
    On-call engineers start from a diagnosis instead of a blank page.
  • Vauris.aiReusable agent skills · drift control · CI evals

    Spec-driven development with agent skills

    55% → 80%first-pass acceptance of generated code
    Challenge
    Generated code drifted over long-running agent tasks, creating review churn.
    Approach
    Specs and reusable agent skills became the source of truth for code generation, with regression evals in CI blocking deploys on score drops.
    Outcome
    Higher-quality output and fewer review cycles per feature (~40% fewer).

04 · Values

Technology should make work more human, not less.

The principles behind how I build and lead — each one backed by something I've actually done.

  • People stay in charge

    Agents escalate when they're unsure and high-risk actions need human approval. Automation should support judgement, not replace it.

    Human-approval gates and escalation paths in my production agents

  • Lift the team

    I stay close to the code so I can unblock people, and I invest in 1:1s, growth plans and honest feedback.

    2 internal promotions from engineers I mentored

  • Prove it, don't promise it

    Every system is measured for faithfulness, latency and cost, and releases are blocked when scores regress.

    Eval suites gating releases in CI

  • Remove friction for people

    The best AI work I've done gave colleagues and customers time back — faster onboarding, faster answers, faster incident resolution.

    Onboarding from a month to days

  • Trust through security

    Data stays where it belongs. Strict tenant isolation, least-privilege tools and red-teaming are part of the design, not an afterthought.

    ~60 red-team probes run on every release

  • Curious across cultures

    I've studied and worked in Pakistan, Malaysia and Germany, and I value the perspectives a diverse team brings.
