Things I do for love and to pay bills. Everything else that wouldn't leave me alone.
My research asks how a drone can make good decisions on its own: perceiving its surroundings, weighing options under uncertainty and energy limits, and acting with a reason it can show. Solar-electric flight is the complementary line, extending endurance so the decisions have time to matter.
Design and analysis of a solar-powered quadcopter, written for my BEng in Aeronautical Engineering at Nanchang Hangkong University. It is the honest starting point of the parity question the current software now answers reproducibly: can a solar multirotor ever harvest as much energy as it consumes? The reproducible answer is no, and the reason shapes the research.

The parity result as a citable paper: a 3 kg quadcopter with 1 square metre of panel harvests 1,567 Wh against 6,613 Wh consumed over a Dhaka solstice day, and even tripled sunlight cannot close the gap. Code and figures archived on Zenodo. A second version is in preparation: all three validations are complete (sky model checked against PVGIS satellite data, the AtlantikSolar 81-hour flight reproduced, hover power recalibrated against real data), and the paper is being rebuilt toward journal submission. doi.org/10.31224/8404

Eight open-source Python projects, each with a full automated test suite, continuous integration, and a public release. Every number quoted on this site can be checked against the code. Plus one native Android app, below.
Solar UAV endurance simulator. Simulates a solar drone across 24 hours with real solar geometry, panel and battery models, and momentum-theory propulsion, then solves for charge-consumption parity. Headline result: a 3 kg quadcopter with 1 square metre of panel harvests 1,567 Wh against 6,613 Wh consumed over a Dhaka solstice day, and the parity solver shows even tripled sunlight cannot close the gap. Grows out of my 2022 undergraduate thesis.
Onboard autonomy simulation. A drone in a grid world senses obstacles within a limited radius, plans with A*, replans in flight when the world changes, and follows a battery-reserve rule that sends it home when continuing is unsafe. Every decision is logged with its reason.
Counter-drone defence simulation for research and education. Noisy detection, Kalman filter tracking, a documented threat score, proportional-navigation guidance for a low-cost interceptor, and seeded Monte Carlo analysis: intercept probability 0.680, USD 643 per successful intercept against USD 64,338 for a missile-class system using publicly reported estimates. v1.1.0 adds an interceptor energy budget, so guidance comparisons price flight time honestly.
International Standard Atmosphere and aerodynamics utilities. Atmosphere state to 51 km, airspeed conversions, Reynolds and Mach, lift, drag, and stall speed. Reproduces the official ISA table values. v1.1.0 adds an altimetry toolkit: pressure and density altitude from real measurements, QNH/QFE reduction, and altimeter settings, with the test suite at 42.
METAR aviation weather decoder. Raw airport weather reports parsed into structured data and plain English. Pure Python standard library, zero dependencies.
ICAO NOTAM decoder. Raw NOTAM text parsed into structured data and plain English: Q-code decoding per ICAO Doc 8126, schedule and abbreviation expansion, height limits, and a plain-language summary. Pure Python standard library, zero dependencies. 47 pytest checks.
Native Android app (Kotlin): the open-source flight intelligence app for Android. Six tabs (Radar, Spotter, Sky, Airports, Tools, Chat): live aircraft, drone, satellite and weather-radar layers fused on one map; point the phone camera at an aircraft and the Spotter names it; satellite passes and airport movements boards; Argus Chat, decentralized chat over Nostr with end-to-end encrypted direct messages and no server. Public APK on GitHub Releases (v2.6.0), in closed testing on the Play Store. v2.6.0 completes the traveller roadmap: a passenger flight diary (add flights by airline and flight number, live match when airborne with position, type and registration), weather-change alerts (15-minute METAR checks per watched airport, plain-English notifications), and a home-screen widget (next satellite pass, nearest airborne aircraft, watched-airport weather). It folds in the v2.5 code: radar timelapse MP4 export and a public Nostr sightings channel. v2.4.0 added an own ADS-B receiver feed (a local dump1090 or readsb endpoint merged into radar, Spotter and Near Me, marked LOCAL) and an offline region pack (cached satellite TLE plus the latest METAR and TAF for chosen airports).
NACA 4-digit airfoil generator and analyzer. Geometry, thin-airfoil theory, Selig and CSV export, plots. Documents openly where thin-airfoil theory departs from wind-tunnel data, and why. v1.1.0 adds a vortex panel method validated against published 2412/0012 reference values.
Multirotor mission feasibility. Waypoints, polygon geofence checks, energy estimates against battery and reserve, and a FEASIBLE, MARGINAL, or INFEASIBLE verdict naming the binding constraint.
solar-uav-sim v1.1.0 is pushed to main (forward-flight power model with a U-shaped power curve and minimum-power cruise speed, plus segment mission pricing; 28 tests green locally) and its release follows once CI is green again. Still to come: panel temperature derating, duty-cycle parity results, and three vehicle classes, feeding the second version of the parity paper and a journal submission. Also in the pipeline: endurance-limited guidance comparisons for counter-uas-sim, larger autonomy scenarios, and a short demo video of the autonomy decision log.

Things I care about: I organized a cleaning campaign with my friends when we went to visit Saint Martin, February 2020 (Daily Star). I volunteered at Bangladesh's first Covid-19 field hospital in Chattogram in April 2020, a once-in-a-lifetime experience (Daily Star).
