About BigByte
We're a product engineering studio built around one belief: founders shouldn't wait months to find out if their product works. We architect and ship production-ready startups in eight weeks, across healthcare, fintech, trading, and more.
Our Story
BigByte was founded in 2021 by engineers who had spent years watching great startup ideas die in slow development cycles. We'd seen it from both sides: as founders who couldn't get good code fast enough, and as engineers frustrated by agencies that treated MVPs like enterprise projects.
We started with one belief: a production-ready product should take weeks, not quarters. We built the process, the team, and the tooling to make that happen. Since then, we've shipped 20+ production systems (telehealth platforms, trading terminals, neobank apps, analytics stacks) without missing a single deadline.
Today BigByte is a tight, senior team of engineers and product thinkers operating from Podgorica, Montenegro, with clients across North America, Europe, and the Middle East. We don't take every project. We take the ones where we can make a genuine, measurable difference.
Our Mission
Most development studios optimise for speed or quality. We optimise for both. Fast means eight weeks from kickoff to production deploy. Right means clean architecture, RLS-enforced security, full-funnel analytics, and a codebase your next engineer can understand on day one. These aren't competing goals. They're the result of a tight process and a senior team that has done this dozens of times.
How We Work
Every engagement starts with architecture review. We design the data model, API boundaries, and deployment strategy before writing line one. That upfront precision is how we move fast without accumulating technical debt.
We don't build throwaway demos. Every line of code we write is production-grade: RLS enabled, error tracking wired, CI/CD running, and a staging environment live before the first feature is complete.
Healthcare, fintech, and trading have non-negotiable requirements. We bring ready-made architectural patterns for each vertical so you're never starting from scratch on HIPAA, PCI, or latency constraints.
99% of our projects land on time. We achieve this by scoping aggressively upfront, running weekly demo checkpoints, and never making promises we can't keep.
You have access to the repository, staging environment, and project tracker from day one. We don't disappear for six weeks and surprise you with a demo.
Your codebase should outlast your engagement with us. We document everything, record walkthroughs, and write code your next developer can understand on day one.
Our Process
Every project follows the same structure. It's tight because it works.
Full data model, API surface, deployment topology, and integration spikes. Every unknown gets resolved before a line of product code is written. This is where projects succeed or fail, and we make sure it's the former.
Database schema, auth flows, RLS policies, and the single most critical user journey built end-to-end. Real code, real database, real deploy. No mockups.
Secondary flows, billing, notifications, admin tooling, and the supporting features that make the product feel complete. Weekly demos every Friday.
Full-funnel event instrumentation, end-to-end tests on the critical journey, load testing on high-traffic endpoints, and cross-device QA.
Production deploy, Core Web Vitals sign-off, monitoring confirmed, documentation written, and a 90-minute codebase walkthrough session with your team.
Tech Philosophy
Our default stack is Next.js, Supabase, TypeScript, and Vercel because it's the fastest path to a production-ready, scalable product for most startup use cases. We deviate when the use case demands it, not because a new framework showed up on Hacker News.
Schema design happens upfront. We understand the query patterns before building and write targeted queries where performance matters, rather than hoping an ORM makes the right call.
Row-level security enforced at the database means a bug in your API cannot leak data. Defence in depth is not optional. It's how we sleep at night.
Your competitive advantage is not infrastructure management. We use Supabase, Vercel, and Sentry so you're not on call for things that aren't your product.
Every product we ship is instrumented with PostHog from day one. You'll know what users do before you have enough of them to run a survey.
Industries We Serve
We don't build generic web apps. We specialise in verticals where engineering decisions have real consequences: regulated data, latency requirements, and compliance obligations that can't be bolted on later. Our experience in healthcare, trading, and fintech isn't background knowledge. It's hands-on knowledge from shipping real products in those spaces.
Building in healthcare means compliance is never optional. We architect every system with HIPAA requirements baked in from the first commit: PHI-safe storage, audit trails, role-based access, and BAA-ready infrastructure. We've shipped telehealth platforms, patient portals, and clinical workflow tools that pass security reviews and earn provider trust.
Trading platforms live and die by latency. We build real-time trading UIs with WebSocket feeds, optimistic UI updates, and order book rendering that doesn't stutter under load. Our platforms handle millions of events per second and stay online when markets move fastest.
From neobank MVPs to payment infrastructure, we build fintech products that clear compliance reviews and earn user trust from day one. KYC/AML onboarding flows, PCI-aware data handling, and real-time transaction analytics, architected correctly the first time.
Client Stories
We measure success by what happens after we hand off: funding raised, users onboarded, and products that scaled without needing a rewrite.
“BigByte understood the sensitivity of our space and shipped a production-ready, HIPAA-compliant platform faster than we thought was possible. Their architecture held up from day one.”
“BigByte took our vision of a modern trading terminal and turned it into a product traders genuinely love. The engineering quality and architecture decisions were exceptional.”
“BigByte understood that fertility data is just as sensitive as any clinical record. They delivered a fast, trustworthy stack (web, app integrations, and analytics) without cutting corners on security or clarity for our users.”
“The AI evaluation engine was the make-or-break feature. Modelling energy costs and investment returns across different regulatory frameworks is genuinely hard, and BigByte nailed it.”
