§ 01 Studio

Pick Three.

fast · secure · affordable — pick three. est. 2025

A software engineering studio. Systems, integrations and AI. Hard problems, effective solutions, no compromises.

§ 02 — Disciplines

Three disciplines. Picked deliberately.

  1. Systems engineering

    5 tags

    Low-level work where the host hardware matters. Rust, C, Go. Distributed systems whose correctness has to survive partitions. We design for the bad day, not the demo.

    Rust Go C Distributed systems Performance
  2. Software integration

    4 tags

    The unglamorous, load-bearing middle. FFI between Rust and Swift. A Python SDK that has to ship on Windows ARM. Two services authored a decade apart that now need a shared event bus.

    FFI SDKs Cross-platform Polyglot codebases
  3. AI engineering

    4 tags

    Production AI infrastructure: agentic systems with real failure modes, RAG that respects the corpus it sits on, evals that survive the next model release. We build the pieces that stay valuable when the foundation model changes.

§ 03 — Method

How we work.

We don't do retainers, time-and-materials, or open-ended advisory. Each engagement is a deliberate three-month contract with a single shape, a single price, and a single deliverable — built, tested, validated, and handed off clean.

Shape

Three months, fixed scope, weekly review. Long enough to ship something real; short enough to stay accountable to it.

Price

Single fee per engagement. Quoted before kickoff. We bill for outcomes, not seats.

Tradeoffs

The opening weeks are for the hard tradeoff conversation. The rest is for executing the answer.

Validation & handoff

Not done until it's tested, validated against the real workload, and handed off with docs, a test suite, and a walkthrough.

GSTeezy

Product · Integration

One platform for all your accounting and tax.

Automates GST compliance and accounting end to end for Indian businesses — reconciles GSTR-2B against your books, reads invoices straight from PDFs with OCR, and connects to the GST portal and Tally directly. Less manual entry, fewer missed input-tax credits, books that stay filing-ready.

nesting

Product · Systems

More garments from every roll of fabric.

An advanced nesting algorithm that arranges garment pieces for cutting at state-of-the-art density — typically 1%+ better material utilization than the tools cutting rooms run today. Fabric is the biggest line on the bill, so every extra percent of a roll is margin recovered on every order.

§ 05 — Engagements

Selected client work.

ACTIVITY · 7-DAY Django → Rust · feature parity

SuperVision

with doox · Integration

Real-time visibility into how teams work.

An employee-productivity platform that shows managers app and website usage, screenshots, and analytics as they happen. We rebuilt it on a Rust backend that serves more clients on less hardware — with faster dashboards and stronger security than the system it replaced.

Rust SQLx WebSocket Django → Rust RBAC
EVENT STREAM nanosecond-resolution clock

NautilusTrader

with Nautech Systems · Systems · AI

From backtest to live — on the same code.

An algorithmic trading platform where the strategy you backtest is the exact code that goes to market — no rewrite, no drift. A high-performance core processes market events at nanosecond resolution, so quant teams move from research to production with confidence.

Rust Python Cython Event-driven Backtesting
§ 06 — Studio

Who we are.

Pick Three is a one-person senior studio. Not an agency, not a body shop. The engineer who scopes your problem is the same engineer who writes the code that ships under the studio's name.

Based in Bangalore, working with clients across three time zones. Happy to sign an NDA after the first conversation — not before.

Systems · Integration · AI

Ishan Bhanuka

B.S. and M.S. in Computer Science. Previously at AWS and Microsoft. Works across all three disciplines — the systems, the integrations, and the AI infrastructure that ship under the studio's name.

§ 07 — Availability

Booking work for Q3.

2 of 3 slots open · next start 14 July

If the work is genuinely in one of our three disciplines, send the shortest possible description of the problem. No deck. No NDA on first contact. We'll reply within two working days with either a tradeoff question or a polite no.
