Joseph Okharedia — Product Engineer

Software is what I've built. Agentic workflows are where I'm headed. Two decades of shipping across industries has taught me that real value comes from moving fast and staying close to the problem.

Experiences

Mar 2025 - Present Staff Software Engineer at Seen
Helping people build or rebuild credit through a mobile-first unsecured credit card product. Working on a credit-building fintech where customers get an unsecured credit card designed to rebuild credit history. Shipping cardholder features in the React Native mobile app — card management, account, and engagement flows. Contributing to underwriting and credit-decisioning flows that determine eligibility, credit limits, and ongoing risk signals — work that sits at the intersection of mobile UX, backend services, communication services, and regulated consumer finance.

Feb 2023 - Oct 2024 Staff Software Engineer at RepubliK
Scaled a web3 creator platform past 1M users by building creator monetization, crypto rewards, wallet infrastructure, AI discovery, and anti-bot systems. Worked on a web3 social platform where creators and communities earn rewards, trade social profiles, monetize exclusive content, and connect crypto wallets. Built configurable airdrop algorithms for distributing RPK rewards across contribution criteria and campaign scenarios. Shipped creator monetization — paid chat access, content paywalls, monthly subscriptions — so creators could earn from exclusive interactions. Integrated Fireblocks custodial wallets for deposits, withdrawals, and token conversion. Took platform architecture from 10,000+ to over 1M users. Improved discovery at scale with AI-driven recommendations and search infrastructure. Strengthened platform integrity with anti-bot protections around high-value reward and trading flows. Created reusable abstractions over critical reward, wallet, and trading flows, and mentored the team on writing stronger tests so they could change those systems with confidence.

Apr 2021 - Jan 2023 Staff Software Engineer at Prosperity
Enabled insurers to launch more engaging, configurable white-labeled life insurance products through better onboarding, experimentation, and maintainable batch-process architecture. Worked on an insurtech platform that helped insurers onboard new clients, bring existing offline customers into the app, and give them access to their portfolio and reports. Ran A/B testing experiments on copy variants and gamified onboarding to improve activation. Refactored the customer-import batch process so it was easier to test, change, and reason about — work that paired with training the team on functional programming patterns adopted across complex flows. Added anomaly checks to scheduled batch processes that caught issues (e.g. duplicate tax-report emails) before they reached more customers.

Dec 2019 - Mar 2021 Senior Software Engineer at Candis
Hardened an accounting automation SaaS by untangling legacy backend services, expanding test coverage, and sharing practical DDD/refactoring patterns. Worked on accounting software used by finance teams to manage documents, approvals, and bookkeeping workflows. Decomposed tangled legacy services into smaller, testable modules so the team could change them with less regression risk. Expanded automated test coverage across critical bookkeeping flows. Ran internal DDD and refactoring workshops — patterns the team continued applying long after the initial work.
