01 / SURVEILLANCE GRID

A hard-edged cone of searchlight rising out of a flat black city skyline and leaving the top of the frame. No mark and no name.

Surveillance grid. A dark instrument panel headed with the window it covers, 07 SEP 2025 to 07 SEP 2026, Under a rail of month names runs a calendar of the whole year, one small square a night, 53 columns of 7, shaded through five cold steps from a barely lit square for a quiet night to a pale one for a heavy night, with no square at all on a night when nothing happened. One square is red: the busiest night of the year. The heaviest month is DEC. Three figures are printed beneath the field: 6,235 events, a typical night of 13, and a busiest night of 88 beside a small red key that points back at that square. The year holds 365 active nights. At the right of the same line a key of five squares runs QUIET to HEAVY.

02 / DOSSIER

A photograph, graded cold. Batman seen from behind and slightly to one side, standing high above Gotham with his cape hanging still. The city falls away below him into haze, its lights small and scattered, and most of the frame is open sky.

I’m a Computer Science student at the University of Chicago specializing in Machine Learning.

I’m interested in software, AI/ML, and research engineering roles. Feel free to reach out if my work seems like a good fit.

I’ve been involved in open source through Google Summer of Code and the Open Source Program Office at UW–Madison.

I built TicketRadar, a ticket discovery platform that received more than 500 waitlist sign-ups and placed top five in the UW–Madison Transcend pitching competition.

I’ve published work in mechanistic interpretability and language-model behavior.

I’m interested in AI safety, reasoning, multi-agent systems, and agent monitoring, with broader interests in evaluations, reinforcement learning, and robotics.

03 / NIGHT WATCH

A dark surveillance record, set in monospace, headed ROLLING RECORD SEP 2025 - SEP 2026. Three large figures across the top: 27 pull requests, 20 merged, 9 repositories they went to. Beneath it, PATROL LOG, a column chart of 13 months of pull request activity running SEP to SEP along a rail of month names. Each column's height is the pull requests opened that month, with the merged share bright at its foot and the rest a dimmer step above; 6 of the 13 draw no column at all and what is drawn stands almost entirely in the last three. The busiest, JUL 2026, carries the chart's only warm mark, a thin red cap, with its count of 11 printed above. Below, SIX HEAVIEST NIGHTS: 6 horizontal bars in date order from 21 SEP to 23 AUG, each with its date at the left and its event count at the right, running 46 to 88. The heaviest, 88 on 23 AUG, is marked PEAK and carries a small red wedge at its tip. A pale hairline stands through all six at a typical night of 13 events, so the longest bar reads as about 7 ordinary nights end to end. A very faint city skyline stands along the bottom edge.

04 / CASE FILES

File E-01 Lexon AI

05 / FIELD RECORD

Field record. 7 entries of previous experience on a dark plate, set as 2 operational chronologies rather than a list of jobs, in record order rather than by date. Each track is a heading over a thin vertical rail; each record is its dates at the left, a small node on the rail, and the organisation with its role and classification under it. FIELD OPERATIONS, engineering, open source, industry. 3 records.

06 / PUBLIC RECORD

The front page of the Gotham Gazette, set flat and square to the frame as a page of type and rules on a steel-grey sheet, with no photograph. The masthead THE GOTHAM GAZETTE runs across the top, with Late City Edition set small beside it, over a heavy rule. The lead headline reads

07 / RAISE THE SIGNAL

EMAIL — tejasdahiya0007@gmail.com

LINKEDIN — linkedin.com/in/tejasdahiya

An empty parapet across the bottom of the frame, its coping catching the city light and turning away at the right, with Gotham lit behind it. A tracking reticle stands on the bare coping with two boot scuffs inside it and reads SUBJECT LOST, and a grapple line is still hooked over the stone beside it. He was never here. Enter the terminal.
