Lijie Li · Data Scientist & Photographer

Designing multilingual knowledge engines that blend Agentic RAG, case-based reasoning, and knowledge graphs for legal intelligence teams.

• Built a multi-hop QA flow that fuses entity extraction with graph traversals for rapid compliance research.
• Introduced quantitative retrieval guardrails using RAGAS and automated regression suites for every release.

Owned the end-to-end lifecycle for policy moderation models, from generative data augmentation to adversarial hardening and deployment.

• Fine-tuned DeBERTaV3 with QLoRA + TPE, cutting VRAM usage by 80% and improving F1 by 5 points.
• Used TextAttack adversarial suites to harden classifiers and validated robustness with macro-F1 and MCC dashboards.

Think of me as the friend who carries cameras, chats through nerves, and helps you leave with portraits you actually like—whether it’s passport refreshes or playful travel diaries.

• Deliver same-day biometric-friendly headshots for visas and IDs, plus natural retouching (skin tones, stray hairs) without the heavy filter look.
• Join shoots as a travel buddy—mapping quiet alleys, cafés, or ferries—so the day feels like hanging out rather than a formal booking.
• Help prep outfits and pacing, but note I can’t stamp or certify official documents—everything stays casual and personal.

Lead relaxed portrait walks through Gamla Stan, Södermalm backstreets, and lakeside trails—no stylists, just a friend with a camera and plenty of time.

• Guide you in prepping outfits and playlists, then stroll together so the shoot feels like catching up rather than performing.
• Capture both candid street frames and clean portraits, retouching lightly while keeping your features and mood intact.
• Share albums plus editing notes so you can re-export or print with the same color story later.
