What Bonvo does.
Six offerings, one standard: senior architectural ownership from first mapping session to hardened production. Every engagement is scoped in writing, executed hands-on, and handed over with the documentation and observability to outlive it.
Legacy Modernization & Zero-Downtime Migration
When a legacy system reaches its breaking point, the dangerous option is the patch. Bonvo specialises in replacing live subsystems while they keep serving traffic — the discipline behind a managed-framework migration that ported 50+ legacy jobs (10,787 LOC across 42 files) off a legacy XMLRPC/TGScheduler jobserver with multi-tenant context restoration, and a core workflow rewritten end to end across 8 versions over 10 months.
What this includes
- Legacy system audit: dependency mapping, risk register, and a sequenced strangler-pattern migration plan
- Zero-downtime cutover design: dual-running, backfill, verification, and rollback paths
- Multi-tenant data and context migration for SaaS platforms
- Post-migration ownership: monitoring, runbooks, and team handover
Distributed & Async Systems Architecture
Queues, workers, schedulers, and long-running pipelines are where platforms quietly rot. Bonvo designs async substrates that are observable, restartable, and boring — the kind that has been owned in production for two years on a contract-intelligence platform where a missed clause-driven deadline can trigger eight-figure liquidated damages.
What this includes
- Task-orchestration and job-substrate architecture (Celery, Redis, PostgreSQL-backed queues)
- Long-running and scheduled pipeline design with idempotency, retries, and multi-tenant isolation
- Distributed-computing workloads — proven at 3M+ data points across 140 simulated years on 96-core GCP instances
- Structured logging, Sentry-grade observability, and stuck-job / DB-lock incident playbooks
Security Review & Vulnerability Research
Bonvo brings vulnerability-research instincts to architecture review: four pre-disclosure security reports filed in 30 days on a single platform — subdomain takeover, a Mersenne-Twister PRNG CSRF weakness, an SMS-MFA-bypass account-takeover chain, and a leaked-credential audit — all framed for ISO 27001 processes.
What this includes
- Authentication, session, and authorization architecture review (SSO, MFA, ATO chains)
- Targeted vulnerability research with pre-disclosure-grade written reports
- CSRF / PRNG / subdomain-takeover class analysis and remediation design
- GDPR, CCPA, ePrivacy and ISO 27001-aware compliance framing for engineering teams
Applied AI & LLM Engineering
Bonvo has been shipping language-model systems since before ChatGPT existed — an OpenAI content-strategy system with A/B testing in production in 2021–22 — and today runs an applied-AI practice around Claude Code, MCP servers, and agent automation, including a 1,000-merge-request review-corpus analysis that produced tooling automating roughly one sixth of recurring review feedback.
What this includes
- LLM pipeline and agent architecture: chains, tool use, MCP server design and deployment
- AI-assisted engineering workflows: CI/CD integration, review automation, slash-command suites in production
- Retrieval and large-scale text processing grounded in real data engineering (100,000+ datapoint pipelines)
- Pragmatic model/vendor selection, evaluation, and cost control — production outcomes over demos
Fractional Architect / Staff Engineer
Some teams don't need a project — they need a senior person in the room, every week. Bonvo offers recurring fractional engagements: architecture direction, design review, incident command, and the mentoring that raises a team's ceiling. The same ownership standard a full-time staff engineer brings — 200 merge requests at a 61.5% merge rate, 138 tickets, 17+ initiative branches owned end to end in the current role — without the full-time seat.
What this includes
- Recurring architecture and design review with written decision records
- Production incident command and post-incident hardening
- Hiring support, code-review standards, and engineering-process design
- A defined weekly cadence with async availability between sessions
Technical Due Diligence
Before you invest in, acquire, or bet your roadmap on a codebase, have an architect read it the way its future owner will. Bonvo's diligence draws on ten years across eCommerce (a 130,000-product catalog), GovTech, health-sector data platforms for WHO & UNICEF stakeholders, and contract intelligence for government and defence clients — plus founder-side experience securing two B2G contracts as co-founder and CEO.
What this includes
- Codebase and architecture assessment: quality, risk, scalability, and hidden coupling
- Infrastructure, security, and compliance posture review
- Team and process evaluation: velocity signals, bus factors, review culture
- A decision-grade written report with a prioritised risk and investment map
