Trading, settlement & data infrastructure for prediction markets.
If you build on, trade on, or are adding Polymarket or Kalshi to your product, I've already shipped every layer you need: market-data pipelines, execution, CTF settlement, custody guards, and billion-event indexing. In production, as sole architect. Five years of mainnet engineering behind it.
A senior-led engineering studio. Every engagement led by Mihir Parmar — no junior hours, ever.

Trading infra
2026 · sole architect · client-deployed
A productized Bun/TypeScript trading stack: CLOB market-data bus with strict hot-path discipline, an executor handling CTF settlement and Safe/EIP-712 signing, two production strategies (fill-avoidance LP-rewards, delta-neutral volume with an enforced economic invariant), an Ed25519-authorized remote command plane, multi-region AWS/Terraform, and an operator CLI with health-gated restarts and auto-rollback — safe enough for a non-technical client to run.

2025–26 · sole author · deployed & verified on Polygon
The full read-and-safety layer for trading Polymarket: an indexer over five Polymarket contracts, an analytics pipeline architected for 2.3B+ on-chain events (ClickHouse + Postgres, FIFO/WAC cost-basis PnL), geo-distributed CLOB latency probes across four AWS regions, and SafeWord — a Gnosis Safe guard that locks a hot bot key to trading-only calls, fuzz- and fork-tested, deployed and verified on Polygon mainnet.
2024 → live 2.5 years · 13 contracts · 4 audit rounds · sole author
A 13-contract UUPS-upgradeable token economy deployed identically to PulseChain and Base mainnet: cross-chain Chainlink VRF randomness, an autonomous on-chain antagonist bounded by timelocks, AWS Lambda keepers driving the game loop, and a self-hosted fork of graph-node. Survived four audit-remediation rounds. The client raised $300k+; the token peaked near $100M FDV; 1,000+ participants — still live today.

Building on Polymarket or Kalshi? Tell me what you're building — I'll tell you the three things most likely to break.
Fast, without the usual cost of fast: we run an agent-assisted engineering workflow gated by 100%-coverage test suites, fuzz/invariant testing, and audit-grade review — it's how a complete on-chain system goes from spec to Ethereum mainnet in a week.
Prepaid · 5 days$2,500
Integration audit
Written review of your Polymarket/Kalshi integration — data pipeline, execution, settlement, custody, latency — with a prioritized fix list and a fixed quote for anything worth building. If it surfaces nothing worth fixing, I refund it.
50% deposit · fixed scopefrom $5,000
Build
Market-data feeds, historical backfills, execution rails, custody guards, strategy infrastructure. Scoped in writing; changes quoted separately. Embed integrations can be structured with builder-fee / revenue-share economics.
Production-grade agent surfaces for protocols and trading products — write operations, simulation, guardrailed money paths. Built by the team behind a 305★ open-source RAG framework and live multi-agent products.
Common questions
Can you start from our existing codebase?
Yes — that's what the audit is for: five days inside your repo and infrastructure, then a written fix list and a fixed quote for anything worth building. Most engagements start there.
How fast can you start?
Audit slots start within the week of payment. Builds are scheduled when the deposit lands. I work UTC+5:30 and keep overlap for US and EU calls.
Who owns what you build?
You do. Fixed-scope work transfers to you in full on final payment — we keep only our pre-existing generic tooling. NDAs are fine.
What's out of scope?
Native mobile apps, from-scratch ML training, and pure design work. If your problem isn't prediction markets, trading infrastructure, or adjacent on-chain systems, I'll say so on the call and point you somewhere better.
Why not hire someone full-time?
For less than a month of a senior trading-infra salary you get the system built by someone who has already made these mistakes on his own book — and if you hire later, the audit document doubles as their onboarding.
Who actually does the work?
Every engagement is led personally by Mihir — architecture, code review, and the final merge. Delivery runs through the studio: specialist collaborators where a build needs them, and an agent-amplified pipeline gated by the same test-coverage and review discipline as everything on this page. You never pay for junior hours; there are none.
Book 30 minutes
Bring the system you're building or the strategy you want to run. You'll leave the call knowing exactly what to build, what it costs, and what to avoid — whether or not we work together.
