General / Portfolio
I connect mechanical engineering, energy-system modelling and software development. My background spans thermal-fluid research at Siemens Energy, industrial energy methodology at Alleima and backend development at QBurst.
01 / Selected work
A focused selection. Open a case study for methods, results and limitations, or follow the skill dossiers below for the complete related record.
An open-source two-boiler steam-and-power twin with a carbon-aware Pyomo/HiGHS scheduler, OpenModelica FMI 2.0 simulation and a local Streamlit advisory GUI. Synthetic and uncalibrated; not an ABB product or live control system.

Seven months embedded at Siemens Energy Finspång conducting compressible CFD/CHT, high-temperature instrumentation and root-cause analysis for the Pulsatorn dynamic pressure sensor calibration rig.
ANSYS Fluent · CFD/CHT · k-omega SST · NI-DAQ · LabVIEW · Siemens NX
Local electricity-investment GUI and shared Pyomo/HiGHS planner, with audited market coverage and 175 extracted public input references. Synthetic and uncalibrated; normalization, price-target decisions and weather conversion still gate historical fitting.

How does energy use change with production? Baseline normalisation and residual diagnostics checked against known-linear data, with explicit missing-meter handling. Alerts are not root-cause diagnoses.

02 / Experience
Seven months embedded at Siemens Energy Finspang in the Fluid Dynamic Lab. Conducted numerical investigation of steady-state thermo-fluid performance of a reducer geometry for a high-temperature dynamic pressure sensor calibration rig (Pulsatorn). Built compressible CFD and conjugate heat transfer models in ANSYS Fluent (k-omega SST), conducted three-level mesh independence study, and applied Biot number analysis to decompose thermal performance. Identified flow-regime asymmetry between geometry variants (Ma 0.990 near-choked vs Ma 1.006 supersonic vena contracta). Also commissioned NI-DAQ measurement chains, modified LabVIEW VIs, ran independent test campaigns at up to 700 C, and conducted a formal root cause analysis of a heater failure resulting in an approved project scope revision. Used Siemens NX and Teamcenter PLM2020 throughout. Supervisor: Prof. Jens Fridh, KTH. Thesis: TRITA-ITM-EX 2026:14.

Developed and independently validated a quantitative methodology for industrial energy performance mapping, covering KPI/EnPI design, load-driver logic, metering-gap assessment, deviation detection from noisy operational data and regulatory comparison. The work was desk-based method development and decision-support framing rather than hands-on plant execution, with electrical utilities and compressed air treated as relevant electrification pathways.

Implemented and maintained backend API endpoints in TypeScript/NestJS, delivered reliability fixes, wrote endpoint tests including negative-path validation and used Postman automation in production-oriented agile teams.

Contributed to KTH plastic pyrolysis research by reviewing reactor concepts and cost-analysis drivers for oil extraction from polymer waste, supporting early-stage technical and economic feasibility evaluation.
03 / Skills & evidence
Each skill opens its own page with all related public projects, roles, coursework, training and supporting material.
04 / Education
Master’s programme in heat and power, energy systems and numerical methods. Thesis completed; 115 hp recorded in the May 2026 transcript.
Mechanical engineering foundation with coursework, design competitions and the final-year interactive robot project.
Credited exchange elective covering lifecycle and circular-economy perspectives on energy storage; not a separate degree.
05 / Supporting material
This is a cross-disciplinary selection, not a claim of equal depth in every area. Professional roles, academic projects and independent tools are labelled separately. The thesis had experimental limitations; industrial work does not establish plant savings, and exploratory models are not validated system forecasts.
Source case studies remain authoritative. Private inputs and restricted project details are not published.
