Executed RLHF campaigns to optimise State-of-the-Art (SOTA) text-to-image diffusion models, directly influencing model convergence and alignment with human intent. Engineered multi-dimensional evaluation taxonomies to quantify model performance across Semantic Alignment, Spatial Consistency, and Prompt Adherence, moving beyond subjective scoring to statistically significant metrics. Conducted failure mode analysis on generative outputs, specifically identifying and categorising topological anomalies (e.g.

Utilized Reinforcement Learning from Human Feedback (RLHF) to improve the training efficiency of machine learning models. Performed prompt engineering with varied parameters to evaluate and optimize model outputs. Conducted Quality Assurance (QA) reviews on prompts and instruction adherence for fellow analysts. Ensured model compliance with safety, truthfulness, and ethical standards.

Assisted field teams in the isolation, testing, and earthing of high voltage equipment, including switchgear and transformers. Executed routine inspections and preventive maintenance on LV/HV lines to enhance system reliability. Successfully resolved faults on LV/HV lines, reducing outage durations and restoring supply to customers. Commissioned secondary transformers and strictly applied safety protocols such as Lockout/Tagout.

Participated in the repair of distribution transformers, including untanking, rewinding, and testing procedures. Conducted critical electrical testing including vector group verification, insulation resistance, and dielectric withstand tests. Collaborated with Quality Assurance teams to ensure the reliable performance of refurbished substation equipment.

Commissioned transformer protection systems, focusing on differential, overcurrent, and voltage regulation schemes. Tested feeder and distance protection relays to ensure adherence to technical specifications. Verified the proper operation of circuit breakers to maintain overall grid reliability.
