## Work experience

Project Engineer \(Optics\) at Indian Institute of Astrophysics \( IIA\), Apr 2025 \- Present · 1 yr 6 mos, Bengaluru, Karnataka, India, 1\) Perform metrology and optical integration of space\-qualified payloads, validating system performance against mission\-critical specifications\. 2\) Conduct interferometric inspection and wavefront error analysis to verify element\-level and system\-level optical parameters including focal length, back focal length, and wavefront residual error\. 3\) Execute alignment procedures using theodolites and alignment cubes for precise optical axis transfer, sensor centration, and field\-of\-view measurements\. 4\) Performed stray light analysis and transmission efficiency testing on space\-grade optical assemblies\. 5\) Led environmental qualification testing \(vibration, thermovacuum, shock, acceleration\) to verify optical system robustness against space launch conditions\. 6\) Collaborated cross\-functionally with mechanical and software engineering teams to diagnose and resolve integration issues, ensuring conformance to space\-grade performance requirements\.

Optical Engineer at Tractrix Opto Dynamics, Apr 2023 \- Mar 2025 · 2 yrs, Hyderabad, Telangana, India, 1\) Assembling and alignment of optical components in an optical system such as open\- and closed\-loop adaptive optics system, spectrometer, off\-axis collimator and helmet\-mounted display 2\) Adaptive Optics System Design: Designed and optimized an adaptive optics system using Zemax\. Implemented the system and studied aberrations using Shack\-Hartmann wavefront sensors in a clean room environment 3\) Turbulence Simulations: Conducted atmospheric turbulence simulations using MATLAB and Python, reaching frequencies of up to 50 Hz 4\) AO Test Bench: Controlled a deformable mirror in an Adaptive Optics \(AO\) test bench with an FPGA controller, calibrated the system, developed software for spontaneous Point Spread Function \(PSF\) measurement, and completed active aberration correction 5\) Spectrometer Development: Contributed to developing a cost\-friendly spectrometer that provides UV\-vis spectra in spectacles to ensure the coating quality

Master Thesis at IISER Mohali, Dec 2021 \- Apr 2022 · 5 mos, Punjab, India, Designing a photoacoustic computed tomography\(PACT\) set up to obtain the photoacoustic imaging of hair strands • Did literature review on Photoacoustic effect, fiber sensors, PACT and other computed tomography • Made a working rotor model of PACT using NEMA\-17 stepper motor, Arduino Mega microcontroller, L293D motor driver, and used IR LED and photodiode to control the rotation data\. The setup was calibrated using time of flight data • Made a Phantom using Agar\-Agar and dipped it in a hairstrand for study\. The whole system was kept inside a container filled with water for coupling • Using a high pulsed red led source, linear ultrasound transducer array data acquisition was done\. An inverse radon function was performed on these raw data to get 2D images of the hair strand

Bachelor Thesis at International School of Photonics, CUSAT, Dec 2019 \- Apr 2020 · 5 mos, • Study on Nonlinear optical response of pyrromethene \(PM\-567\) dissolved in ethanol by the technique of Spatial self\-phase modulation \(SSPM\)with a continuous wave \(CW\) laser • Did literature review mainly on nonlinear techniques Kerr effect, self\-focusing, self\-phase modulation, spatial self\-phase modulation, and pyrromethene 567 dye • Assembled and aligned optical components such as solid\-state diode laser of 532nm, convex lens, quartz cuvette with ethanol and pyrromethene solution • Observed a series of concentric circles with a CMOS sensor, also noted the number of rings directly depends on the input power applied\. With the known and observed parameters calculated the third\-order nonlinear susceptibility
