Applied AI Research & Engineering Profile
As a Senior AI Research Engineer & Generative AI Specialist at SoftBrixAI, Ahmad Jajja leads the research, prototyping, and production deployment of state-of-the-art Generative AI models, contextual intelligence engines, and complex Retrieval-Augmented Generation (RAG) pipelines.
Currently pursuing advanced graduate research in Computer Science at Montana State University, Ahmad combines academic depth with pragmatic engineering execution. He was recognized as an International AI Hackathon Winner at lablab.ai (Unhallucinate Challenge), where his team engineered novel automated hallucination detection systems for enterprise language models. Furthermore, he was selected as a Section Leader at Stanford University (Code in Place), mentoring over 100 international students in rigorous Python and software fundamentals.
Generative AI, RAG Systems & Hallucination Mitigation
Ahmad specializes in transforming raw foundational models into accurate, hallucination-resistant enterprise AI systems tailored for high-stakes business environments:
- Production-Grade RAG Architectures: Engineering hybrid search architectures combining dense vector embeddings with sparse lexical indexing (BM25 + SPLADE) and cross-encoder re-ranking for maximum contextual recall.
- Automated Hallucination Detection & Mitigation: Designing factual verification layers, citation grounding pipelines, and self-reflective query loops that audit model outputs against authoritative enterprise document repositories before response delivery.
- Context Window Optimization & Chunking Strategies: Implementing semantic document chunking, dynamic context routing, and lost-in-the-middle mitigation to maximize prompt density and minimize token costs.
- Autonomous Tool-Augmented Agents: Developing custom function-calling agents capable of interacting with enterprise APIs, SQL databases, and internal analytics engines with zero drift.
Model Fine-Tuning, Quantization & Open-Source LLMs
Ahmad conducts hands-on research and implementation for localizing and optimizing open-weights foundation models for private client infrastructure:
- Parameter-Efficient Fine-Tuning (PEFT): Fine-tuning domain-specialized models (Llama, Mistral, Qwen, DeepSeek) using LoRA, QLoRA, and FlashAttention-2 on constrained GPU infrastructure.
- Model Alignment & Preference Optimization: Applying Direct Preference Optimization (DPO) and Reinforcement Learning from Human Feedback (RLHF) principles to align model tone, safety guardrails, and deterministic formatting.
- Quantization & Edge Inference: Compressing deep neural networks using 4-bit and 8-bit quantization (AWQ, GPTQ, GGUF) to maximize inference throughput while preserving task accuracy.
Algorithmic Rigor, Data Science & Technical Education
With a deep background in competitive programming (having solved 300+ advanced Data Structures & Algorithms problems on LeetCode) and technical education, Ahmad leads SoftBrixAI’s open-source knowledge initiatives:
- Scalable Machine Learning & Data Pipelines: Building production data preparation and feature engineering pipelines using Python, PyTorch, NumPy, and Pandas.
