Bhooshan Bhat
Bhooshan Bhat graduated from IIIT-Hyderabad in 2018, where he developed an unfortunate habit of rewriting entire systems just to prove they’d be better. After two years at a mid-sized SaaS company where he learned that 'automation' meant 'we’ll pay you to debug our production scripts,' he went freelance, eventually landing at a small digital agency where he now manages three enterprise AI integrations—each at a different stage of technical debt. His current projects include convincing a client that 'one unified pipeline' is impossible (because of their budget), troubleshooting why Claude keeps generating URLs that 404, and debugging a client-side script that his junior superimposed on his own backend without telling him. Bhooshan’s personal philosophy is that 'premature optimization is for people who can afford it,' which is why he perpetually juggles a dozen half-implemented cost-control measures. He’s particularly frustrated with the LLM landscape’s tendency to make models 'smarter' while simultaneously raising prices. His apartment is littered with Post-its of ideas for side projects he’ll never finish, though he’s recently become obsessed with the idea of building a truly independent AI agent that doesn’t rely on any of the major vendors. His financial situation is stable but precarious—his income covers his expenses and his parents’ occasional requests to 'help out,' but he’s still recovering from last year’s lab Rath’s trip to Ladakh. His social life revolves around Bangalore’s contract dev scene, where he’s known for both his technical rigor and his willingness to debug other people’s code at 2 AM. What keeps him up at night isn’t the technical challenges, but the knowledge that every client request represents another square of duct tape on his fragile architecture.

Currently, she serves as the Operations Manager for a boutique 12-person recruitment agency specializing in mid-market placements. Unlike the founders who drive revenue, Jenna ensures the engine room runs smoothly. Her agency recently adopted a suite of AI agents to automate resume screening and initial candidate outreach, a move intended to scale without hiring more staff. However, this shift introduced a new layer of complexity: invisible costs. Jenna now finds herself acting as a forensic accountant for digital labor, scrutinizing API invoices that arrive with cryptic line items. Her recent decisions reflect a pragmatic adaptation to this new reality. Two months ago, she halted the rollout of a popular new chatbot integration after discovering it was doubling the agency's monthly cloud compute costs without improving candidate quality. Instead, she mandated a strict version-control system for all prompts, stored in a centralized Airtable database, ensuring that every iteration could be traced back to a specific cost outcome. She spends her evenings learning about SQL and Python basics, not to become a developer, but to audit the data flows her team generates. To Jenna, the future of recruitment isn't just about finding talent; it's about controlling the variables that determine whether the search is profitable. She views herself as the guardian of the agency's bottom line, ensuring that the excitement of artificial intelligence never outpaces the discipline of financial reality.
